Mockery is a project that creates mock implementations of Golang interfaces. The mocks generated in this project are based off of the github.com/stretchr/testify suite of testing packages.

When you have an interface like this:
 db.go
type DB interface {\n    Get(val string) string\n}\n
 
and a function that takes this interface:
 db_getter.go
func getFromDB(db DB) string {\n    return db.Get(\"ice cream\")\n}\n
 
You can test getFromDB by either instantiating a testing database, or you can simply create a mock implementation of DB using mockery. Mockery can automatically generate a mock implementation that allows us to define assertions on how the mock was used, what to return, and other useful tidbits. We can add a //go:generate directive above our interface:
 db.go
//go:generate mockery --name DB\ntype DB interface {\n    Get(val string) string\n}\n

These options are only compatible with non-regular expressions in name, where only one mock is generated. inpackage-suffix When inpackage-suffix is set to True, mock files are suffixed with _mock instead of being prefixed with mock_ for InPackage mocks inpackage and keeptree For some complex repositories, there could be multiple interfaces with the same name but in different packages. In that case, inpackage allows generating the mocked interfaces directly in the package that it mocks. In the case you don't want to generate the mocks into the package but want to keep a similar structure, use the option keeptree. name The name option takes either the name or matching regular expression of the interface to generate mock(s) for. output mockery always generates files with the package mocks to keep things clean and simple. You can control which mocks directory is used by using output, which defaults to ./mocks. outpkg Use outpkg to specify the package name of the generated mocks. print Use print: True to have the resulting code printed out instead of written to disk. recursive Use the recursive option to search subdirectories for the interface(s). This option is only compatible with name.

    This parameter directs Mockery on whether it should resolve a type alias to its underlying, real type or if it should generate mocks by referencing. Mockery was changed in #808 to support a new language feature that exposed type aliases in the parsed syntax tree. This meant that Mockery was now explicitly aware of aliases, which fixed a number of problems:
     
       
    • #803
      •  
    • #331
      •  
     
    However, it was discovered in #839 that this was in fact a backwards-incompatible change. Thus, to maintain backwards compatability guarantees, we created this parameter that will be set to True by default.
     
    For all new projects that use Mockery, there is no reason to resolve type aliases so this parameter should almost always be set to False. This will be the permanent behavior in Mockery v3.

    Tip
     
    IDEs are really useful when interacting with mockery objects. All mockery objects embed the github.com/stretchr/testify/mock.Mock object so you have access to both methods provided by mockery, and from testify itself. IDE auto-completion will show you all methods available for your use.

    Given this interface:
     string.go
    package example_project\n\ntype Stringer interface {\n    String() string\n}\n
     
    Create a mock for this interface by specifying it in your config. We can then create a test using this new mock object:
     string_test.go
    package example_project\n\nimport (\n    \"testing\"\n\n    \"github.com/stretchr/testify/assert\"\n)\n\nfunc Foo(s Stringer) string {\n    return s.String()\n}\n\nfunc TestString(t *testing.T) {\n    mockStringer := NewMockStringer(t)\n    mockStringer.EXPECT().String().Return(\"mockery\")\n    assert.Equal(t, \"mockery\", Foo(mockStringer))\n}\n
     
    Note that in combination with using the mock's constructor and the .EXPECT() directives, your test will automatically fail if the expected call is not made. 
     Alternate way of specifying expectations 
    You can also use the github.com/stretchr/testify/mock.Mock object directly (instead of using the .EXPECT() methods, which provide type-safe-ish assertions).
     string_test.go
    func TestString(t *testing.T) {\n    mockStringer := NewMockStringer(t)\n    mockStringer.On(\"String\").Return(\"mockery\")\n    assert.Equal(t, \"mockery\", Foo(mockStringer))\n}\n
     
    We recommend always interacting with the assertions through .EXPECT() as mockery auto-generates methods that call out to Mock.On() themselves, providing you with some amount of compile-time safety. Consider if all your expectations for String() use the Mock.On() methods, and you decide to add an argument to String() to become String(foo string). Now, your existing tests will only fail when you run them. If you had used .EXPECT() and regenerated your mocks after changing the function signature, your IDE, and the go compiler itself, would both tell you immediately that your expectations don't match the function signature.

    The replace-type parameter allows adding a list of type replacements to be made in package and/or type names. This can help overcome issues like usage of type aliases that point to internal packages.
     
    The format of the parameter is:
     
    originalPackagePath.originalTypeName=newPackageName:newPackagePath.newTypeName
     
    For example:
     Bash
    mockery --replace-type github.com/vektra/mockery/v2/baz/internal/foo.InternalBaz=baz:github.com/vektra/mockery/v2/baz.Baz\n
     
    This will replace any imported named \"github.com/vektra/mockery/v2/baz/internal/foo\" with baz \"github.com/vektra/mockery/v2/baz\". The alias is defined with : before the package name. Also, the InternalBaz type that comes from this package will be renamed to baz.Baz.
     
    This next example fixes a common problem of type aliases that point to an internal package.
     
    cloud.google.com/go/pubsub.Message is a type alias defined like this:
     Go
    import (\n    ipubsub \"cloud.google.com/go/internal/pubsub\"\n)\n\ntype Message = ipubsub.Message\n
     
    The Go parser that mockery uses doesn't provide a way to detect this alias and sends the application the package and type name of the type in the internal package, which will not work.
     
    We can use replace-type with only the package part to replace any import of cloud.google.com/go/internal/pubsub to cloud.google.com/go/pubsub. We don't need to change the alias or type name in this case, because they are pubsub and Message in both cases.
     Bash
    mockery --replace-type cloud.google.com/go/internal/pubsub=cloud.google.com/go/pubsub\n
     
    Original source:
     Go
    import (\n    \"cloud.google.com/go/pubsub\"\n)\n\ntype Handler struct {\n    HandleMessage(m pubsub.Message) error\n}\n
     
    Invalid mock generated without this parameter (points to an internal folder):
     Go
    import (\n    mock \"github.com/stretchr/testify/mock\"\n\n    pubsub \"cloud.google.com/go/internal/pubsub\"\n)\n\nfunc (_m *Handler) HandleMessage(m pubsub.Message) error {\n    // ...\n    return nil\n}\n
     
    Correct mock generated with this parameter.
     Go
    import (\n    mock \"github.com/stretchr/testify/mock\"\n\n    pubsub \"cloud.google.com/go/pubsub\"\n)\n\nfunc (_m *Handler) HandleMessage(m pubsub.Message) error {\n    // ...\n    return nil\n}\n
     
    Generic type constraints can also be replaced by targeting the changed parameter with the square bracket notation on the left-hand side.
     Bash
    mockery --replace-type github.com/vektra/mockery/v2/baz/internal/foo.InternalBaz[T]=github.com/vektra/mockery/v2/baz.Baz\n
     
    For example:
     Go
    type InternalBaz[T any] struct{}\n\nfunc (*InternalBaz[T]) Foo() T {}\n\n// Becomes\ntype InternalBaz[T baz.Baz] struct{}\n\nfunc (*InternalBaz[T]) Foo() T {}\n
     
    If a type constraint needs to be removed and replaced with a type, target the constraint with square brackets and include a '-' in front to have it removed.
     Bash
    mockery --replace-type github.com/vektra/mockery/v2/baz/internal/foo.InternalBaz[-T]=github.com/vektra/mockery/v2/baz.Baz\n
     
    For example:
     Go
    type InternalBaz[T any] struct{}\n\nfunc (*InternalBaz[T]) Foo() T {}\n\n// Becomes\ntype InternalBaz struct{}\n\nfunc (*InternalBaz) Foo() baz.Baz {}\n
     
    When replacing a generic constraint, you can replace the type with a pointer by adding a '*' before the output type name.
     Bash
    mockery --replace-type github.com/vektra/mockery/v2/baz/internal/foo.InternalBaz[-T]=github.com/vektra/mockery/v2/baz.*Baz\n
     
    For example:

    Info
     
    See the Migration Docs on how to migrate to this new feature.
     
    Mockery has a configuration parameter called packages. In this config section, you define the packages and the interfaces you want mocks generated for. The packages can be any arbitrary package, either your own project or anything within the Go ecosystem. You may provide package-level or interface-level overrides to the default config you provide.
     
    Usage of the packages config section is desirable for multiple reasons:
     
       
    1. Up to 5x increase in mock generation speed over the legacy method
      2.  
    2. Granular control over interface generation, location, and file names
      3.  
    3. Singular location for all config, instead of spread around by //go:generate statements
      4.  
    4. Clean, easy to understand.
      5.  
    "},{"location":"features/#examples","title":"Examples","text":"
    Here is an example configuration set:
     YAML
    with-expecter: True\npackages:\n  github.com/vektra/mockery/v2/pkg: # (1)!\n    interfaces:\n      TypesPackage:\n      RequesterVariadic:\n        config: # (2)!\n          with-expecter: False \n        configs:\n          - mockname: MockRequesterVariadicOneArgument\n            unroll-variadic: False\n          - mockname: MockRequesterVariadic\n  io:\n    config:\n      all: True # (3)!\n    interfaces:\n      Writer:\n        config:\n          with-expecter: False # (4)!\n
     
       
    1. For this package, we provide no package-level config (which means we inherit the defaults at the top-level). Since our default of all: is False, mockery will only generate the interfaces we specify. We tell it which interface to generate by using the interfaces section and specifying an empty map, one for each interface.
      2.  
    2. There might be cases where you want multiple mocks generated from the same interface. To do this, you can define a default config section for the interface, and further configs (plural) section, one for each mock. You must specify a mockname for the mocks in this section to differentiate them.
      3.  
    3. This is telling mockery to generate all interfaces in the io package.

     v2.25.0
     
    When recursive: true is set on a particular package:
     YAML
    packages:\n  github.com/user/project:\n    config:\n      recursive: true\n      with-expecter: true\n
     
    mockery will dynamically discover all sub-packages within the specified package. This is done by calling packages.Load on the specified package, which induces Go to download the package from the internet (or simply your local project). Mockery then recursively discovers all sub-directories from the root package that also contain .go files and injects the respective package path into the config map as if you had specified them manually. As an example, your in-memory config map may end up looking like this:
     YAML
    packages:\n  github.com/user/project:\n    config:\n      recursive: true\n      with-expecter: true\n  github.com/user/project/subpkg1:\n    config:\n      recursive: true\n      with-expecter: true\n  github.com/user/project/subpkg2:\n    config:\n      recursive: true\n      with-expecter: true\n
     
    You can use the showconfig command to see the config mockery injects. The output of showconfig theoretically could be copy-pasted into your YAML file as it is semantically equivalent.
     
    mockery will not recurse into submodules, i.e. any subdirectory that contains a go.mod file. You must specify the submodule as a separate line item in the config if you would like mocks generated for it as well.
     performance characteristics 
    The performance when using recursive: true may be worse than manually specifying all packages statically in the YAML file. This is because of the fact that mockery has to recursively walk the filesystem path that contains the package in question. It may unnecessarily walk down unrelated paths (for example, a Python virtual environment that is in the same path as your package). For this reason, it is recommended not to use recursive: true if it can be avoided.
    "},{"location":"features/#regex-matching","title":"Regex matching","text":"
    You can filter matched interfaces using the include-regex option. To generate mocks only for interfaces ending in Client we can use the following configuration:

    To further refine matched interfaces, you can also use exclude-regex. If an interface matches both include-regex and exclude-regex then it will not be generated. For example, to generate all interfaces except those ending in Func:
     YAML
    packages:\n  github.com/user/project:\n    config:\n      recursive: true\n      include-regex: \".*\"\n      exclude-regex: \".*Func\"\n
     
    You can only use exclude-regex with include-regex. If set by itself, exclude-regex has no effect.

     v2.10.0 \u00b7 with-expecter: True
     
    Mockery now supports an \"expecter\" struct, which allows your tests to use type-safe methods to generate call expectations. When enabled through the with-expecter: True mockery configuration, you can enter into the expecter interface by simply calling .EXPECT() on your mock object.
     
    For example, given an interface such as Go
    type Requester interface {\n    Get(path string) (string, error)\n}\n
     
    You can use the expecter interface as such: Go
    requesterMock := mocks.NewRequester(t)\nrequesterMock.EXPECT().Get(\"some path\").Return(\"result\", nil)\n
     
    A RunAndReturn method is also available on the expecter struct that allows you to dynamically set a return value based on the input to the mock's call.
     Go
    requesterMock.EXPECT().\n    Get(mock.Anything).\n    RunAndReturn(func(path string) (string, error) { \n        fmt.Println(path, \"was called\")\n        return (\"result for \" + path), nil\n    })\n
     
    Note
     
    Note that the types of the arguments on the EXPECT methods are interface{}, not the actual type of your interface.

The types are still provided in the expecter method docstrings.

    Return Value Providers can be used one of two ways.

If you are using the second form, for each of the return values of the mocked function, Return needs a function which takes the same arguments as the mocked function, and returns one of the return values. For example, if the return argument signature of passthrough in the above example was instead (string, error) in the interface, Return would also need a second function argument to define the error value:

    mockery was built during the pre-module era of Golang. Much of its codebase and configuration syntax was designed around file-based operations. This model became highly inefficient once Golang migrated to module-based packages. The old configuration semantics also proved limiting -- many users introduced and requested feature additions to mockery to support esoteric use-cases. This proved to be a huge maintenance burden that existed solely because the configuration model could not flexibly describe all the situations users wanted. The packages semantics provides us a few highly desirable traits:
     
       
    1. Orders of magnitude performance increase, due to calling packages.Load once or twice for an entire project, versus once per file in the legacy semantics.
      2.  
    2. Hierarchical configuration model that allows interface-specific config to be inherited from package-level config, which is inherited from defaults.
      3.  
    3. Single configuration file that describes the entirety of mockery's behavior, instead of spread out by //go:generate statements.

    The legacy config provided the inpackage parameter which, if inpackage: True, would place the mocks in the same package as your interfaces. Otherwise, it would place it in a separate directory.
     
    These two layouts are supported in the packages scheme. See the relevant docs here.

    When using the packages feature, recursive: true and you have specified a package that contains no *.go files, mockery is unable to determine the on-disk location of the package in order to continue the recursive package search. This appears to be a limitation of the golang.org/x/tools/go/packages package that is used to parse package metadata.
     
    The solution is to create a .go file in the package's path and add a package [name] directive at the top. It doesn't matter what the file is called. This allows mockery to properly read package metadata.

    This issue indicates that you have attempted to use package in your dependency tree (whether direct or indirect) that uses Go language semantics that your currently-running Go version does not support. The solution:
     
       
    1. Update to the latest go version
      2.  
    2. Delete all cached packages with go clean -modcache
      3.  
    3. Reinstall mockery
      4.  
     
    Additionally, this issue only happens when compiling mockery from source, such as with go install. Our docs recommend not to use go install as the success of your build depends on the compatibility of your Go version with the semantics in use. You would not encounter this issue if using one of the installation methods that install pre-built binaries, like downloading the .tar.gz binaries, or through brew install.
    "},{"location":"notes/#multiple-expectations-with-identical-arguments","title":"Multiple Expectations With Identical Arguments","text":"
    There might be instances where you want a mock to return different values on successive calls that provide the same arguments. For example, we might want to test this behavior:
     Go
    // Return \"foo\" on the first call\ngetter := NewGetter()\nassert(t, \"foo\", getter.Get(\"key\"))\n\n// Return \"bar\" on the second call\nassert(t, \"bar\", getter.Get(\"key\"))\n
     
    This can be done by using the .Once() method on the mock call expectation:
     Go
    mockGetter := NewMockGetter(t)\nmockGetter.EXPECT().Get(mock.anything).Return(\"foo\").Once()\nmockGetter.EXPECT().Get(mock.anything).Return(\"bar\").Once()\n
     
    Or you can identify an arbitrary number of times each value should be returned:
     Go
    mockGetter := NewMockGetter(t)\nmockGetter.EXPECT().Get(mock.anything).Return(\"foo\").Times(4)\nmockGetter.EXPECT().Get(mock.anything).Return(\"bar\").Times(2)\n

    Consider if we have a function func Bar(message ...string) error. A typical assertion might look like this:
     Go
    func TestFoo(t *testing.T) {\n  m := NewMockFoo(t)\n  m.On(\"Bar\", \"hello\", \"world\").Return(nil)\n
     
    We might also want to make an assertion that says \"any number of variadic arguments\":
     Go
    m.On(\"Bar\", mock.Anything).Return(nil)\n
     
    However, what we've given to mockery is ambiguous because it is impossible to distinguish between these two intentions:
     
       
    1. Any number of variadic arguments of any value
      2.  
    2. A single variadic argument of any value
      3.  
     
    This is fixed in #359 where you can provide unroll-variadic: False to get back to the old behavior. Thus, if you want to assert (1), you can then do:
     Go
    m.On(\"Bar\", mock.Anything).Return(nil)\n
     
    If you want to assert (2), you must set unroll-variadic: True. Then this assertion's intention will be modified to mean the second case:
     Go
    m.On(\"Bar\", mock.Anything).Return(nil)\n
     
    An upstream patch to testify is currently underway to allow passing mock.Anything directly to the variadic slice: https://github.com/stretchr/testify/pull/1348
     
    If this is merged, it would become possible to describe the above two cases respectively:
     Go
    // case 1\nm.On(\"Bar\", mock.Anything).Return(nil)\n// case 2\nm.On(\"Bar\", []interface{}{mock.Anything}).Return(nil)\n

    This issue was first highlighted in this GitHub issue.
     
    mockery uses the viper package for configuration mapping and parsing. Viper is set to automatically search for all config variables specified in its config struct. One of the config variables is named version, which gets mapped to an environment variable called MOCKERY_VERSION. If you set this environment variable, mockery attempts to parse it into the version bool config.
     
    This is an adverse effect of how our config parsing is set up. The solution is to rename your environment variable to something other than MOCKERY_VERSION.

      The legacy config options will be removed in v3 and are deprecated (but supported) in v2.
       name description all It's common for a big package to have a lot of interfaces, so mockery provides all. This option will tell mockery to scan all files under the directory named by --dir (\".\" by default) and generates mocks for any interfaces it finds. This option implies recursive: True. boilerplate-file Specify a path to a file that contains comments you want displayed at the top of all generated mock files. This is commonly used to display license headers at the top of your source code. case mockery generates files using the casing of the original interface name.  This can be modified by specifying case: underscore to format the generated file name using underscore casing. exclude This parameter is a list of strings representing path prefixes that should be excluded from mock generation. exported Use exported: True to generate public mocks for private interfaces. filename Use the filename and structname to override the default generated file and struct name. These options are only compatible with non-regular expressions in name, where only one mock is generated. inpackage-suffix When inpackage-suffix is set to True, mock files are suffixed with _mock instead of being prefixed with mock_ for InPackage mocks inpackage and keeptree For some complex repositories, there could be multiple interfaces with the same name but in different packages. In that case, inpackage allows generating the mocked interfaces directly in the package that it mocks. In the case you don't want to generate the mocks into the package but want to keep a similar structure, use the option keeptree. name The name option takes either the name or matching regular expression of the interface to generate mock(s) for. output mockery always generates files with the package mocks to keep things clean and simple. You can control which mocks directory is used by using output, which defaults to ./mocks. outpkg Use outpkg to specify the package name of the generated mocks. print Use print: True to have the resulting code printed out instead of written to disk. recursive Use the recursive option to search subdirectories for the interface(s). This option is only compatible with name. The all option implies recursive: True. replace-type source=destination Replaces aliases, packages and/or types during generation. testonly Prepend every mock file with _test.go. This is useful in cases where you are generating mocks inpackage but don't want the mocks to be visible to code outside of tests. with-expecter Use with-expecter: True to generate EXPECT() methods for your mocks.

      This parameter fixes a somewhat uninteresting, but important issue found in #845. In short, mockery ignored the outpkg: parameter if inpackage: was set to True. This prevents users from being able to set alternate package names for their mocks that are generated in the same directory as the mocked interface. For example, it's legal Go to append _test to the mock package name if the file is appended with _test.go as well. This parameter will be permanently enabled in mockery v3.
       
      As an example, if you had configuration that looked like this:

      This parameter directs Mockery on whether it should resolve a type alias to its underlying, real type or if it should generate mocks by referencing. Mockery was changed in #808 to support a new language feature that exposed type aliases in the parsed syntax tree. This meant that Mockery was now explicitly aware of aliases, which fixed a number of problems:

      For all new projects that use Mockery, there is no reason to resolve type aliases so this parameter should almost always be set to False. This will be the permanent behavior in Mockery v3.

      Tip
       
      IDEs are really useful when interacting with mockery objects. All mockery objects embed the github.com/stretchr/testify/mock.Mock object so you have access to both methods provided by mockery, and from testify itself. IDE auto-completion will show you all methods available for your use.

      Given this interface:
       string.go
      package example_project\n\ntype Stringer interface {\n    String() string\n}\n
       
      Create a mock for this interface by specifying it in your config. We can then create a test using this new mock object:
       string_test.go
      package example_project\n\nimport (\n    \"testing\"\n\n    \"github.com/stretchr/testify/assert\"\n)\n\nfunc Foo(s Stringer) string {\n    return s.String()\n}\n\nfunc TestString(t *testing.T) {\n    mockStringer := NewMockStringer(t)\n    mockStringer.EXPECT().String().Return(\"mockery\")\n    assert.Equal(t, \"mockery\", Foo(mockStringer))\n}\n
       
      Note that in combination with using the mock's constructor and the .EXPECT() directives, your test will automatically fail if the expected call is not made. 
       Alternate way of specifying expectations 
      You can also use the github.com/stretchr/testify/mock.Mock object directly (instead of using the .EXPECT() methods, which provide type-safe-ish assertions).
       string_test.go
      func TestString(t *testing.T) {\n    mockStringer := NewMockStringer(t)\n    mockStringer.On(\"String\").Return(\"mockery\")\n    assert.Equal(t, \"mockery\", Foo(mockStringer))\n}\n
       
      We recommend always interacting with the assertions through .EXPECT() as mockery auto-generates methods that call out to Mock.On() themselves, providing you with some amount of compile-time safety. Consider if all your expectations for String() use the Mock.On() methods, and you decide to add an argument to String() to become String(foo string). Now, your existing tests will only fail when you run them. If you had used .EXPECT() and regenerated your mocks after changing the function signature, your IDE, and the go compiler itself, would both tell you immediately that your expectations don't match the function signature.

      The replace-type parameter allows adding a list of type replacements to be made in package and/or type names. This can help overcome issues like usage of type aliases that point to internal packages.
       
      The format of the parameter is:
       
      originalPackagePath.originalTypeName=newPackageName:newPackagePath.newTypeName
       
      For example:
       Bash
      mockery --replace-type github.com/vektra/mockery/v2/baz/internal/foo.InternalBaz=baz:github.com/vektra/mockery/v2/baz.Baz\n
       
      This will replace any imported named \"github.com/vektra/mockery/v2/baz/internal/foo\" with baz \"github.com/vektra/mockery/v2/baz\". The alias is defined with : before the package name. Also, the InternalBaz type that comes from this package will be renamed to baz.Baz.
       
      This next example fixes a common problem of type aliases that point to an internal package.
       
      cloud.google.com/go/pubsub.Message is a type alias defined like this:
       Go
      import (\n    ipubsub \"cloud.google.com/go/internal/pubsub\"\n)\n\ntype Message = ipubsub.Message\n
       
      The Go parser that mockery uses doesn't provide a way to detect this alias and sends the application the package and type name of the type in the internal package, which will not work.
       
      We can use replace-type with only the package part to replace any import of cloud.google.com/go/internal/pubsub to cloud.google.com/go/pubsub. We don't need to change the alias or type name in this case, because they are pubsub and Message in both cases.
       Bash
      mockery --replace-type cloud.google.com/go/internal/pubsub=cloud.google.com/go/pubsub\n
       
      Original source:
       Go
      import (\n    \"cloud.google.com/go/pubsub\"\n)\n\ntype Handler struct {\n    HandleMessage(m pubsub.Message) error\n}\n
       
      Invalid mock generated without this parameter (points to an internal folder):
       Go
      import (\n    mock \"github.com/stretchr/testify/mock\"\n\n    pubsub \"cloud.google.com/go/internal/pubsub\"\n)\n\nfunc (_m *Handler) HandleMessage(m pubsub.Message) error {\n    // ...\n    return nil\n}\n
       
      Correct mock generated with this parameter.
       Go
      import (\n    mock \"github.com/stretchr/testify/mock\"\n\n    pubsub \"cloud.google.com/go/pubsub\"\n)\n\nfunc (_m *Handler) HandleMessage(m pubsub.Message) error {\n    // ...\n    return nil\n}\n
       
      Generic type constraints can also be replaced by targeting the changed parameter with the square bracket notation on the left-hand side.
       Bash
      mockery --replace-type github.com/vektra/mockery/v2/baz/internal/foo.InternalBaz[T]=github.com/vektra/mockery/v2/baz.Baz\n
       
      For example:
       Go
      type InternalBaz[T any] struct{}\n\nfunc (*InternalBaz[T]) Foo() T {}\n\n// Becomes\ntype InternalBaz[T baz.Baz] struct{}\n\nfunc (*InternalBaz[T]) Foo() T {}\n
       
      If a type constraint needs to be removed and replaced with a type, target the constraint with square brackets and include a '-' in front to have it removed.
       Bash
      mockery --replace-type github.com/vektra/mockery/v2/baz/internal/foo.InternalBaz[-T]=github.com/vektra/mockery/v2/baz.Baz\n
       
      For example:
       Go
      type InternalBaz[T any] struct{}\n\nfunc (*InternalBaz[T]) Foo() T {}\n\n// Becomes\ntype InternalBaz struct{}\n\nfunc (*InternalBaz) Foo() baz.Baz {}\n
       
      When replacing a generic constraint, you can replace the type with a pointer by adding a '*' before the output type name.
       Bash
      mockery --replace-type github.com/vektra/mockery/v2/baz/internal/foo.InternalBaz[-T]=github.com/vektra/mockery/v2/baz.*Baz\n
       
      For example:
       Go

      Info
       
      See the Migration Docs on how to migrate to this new feature.
       
      Mockery has a configuration parameter called packages. In this config section, you define the packages and the interfaces you want mocks generated for. The packages can be any arbitrary package, either your own project or anything within the Go ecosystem. You may provide package-level or interface-level overrides to the default config you provide.
       
      Usage of the packages config section is desirable for multiple reasons:
       
         
      1. Up to 5x increase in mock generation speed over the legacy method
        2.  
      2. Granular control over interface generation, location, and file names
        3.  
      3. Singular location for all config, instead of spread around by //go:generate statements
        4.  
      4. Clean, easy to understand.
        5.

      1. For this package, we provide no package-level config (which means we inherit the defaults at the top-level). Since our default of all: is False, mockery will only generate the interfaces we specify. We tell it which interface to generate by using the interfaces section and specifying an empty map, one for each interface.
        2.  
      2. There might be cases where you want multiple mocks generated from the same interface. To do this, you can define a default config section for the interface, and further configs (plural) section, one for each mock. You must specify a mockname for the mocks in this section to differentiate them.
        3.  
      3. This is telling mockery to generate all interfaces in the io package.

      packages:\n  github.com/user/project:\n    config:\n      recursive: true\n      with-expecter: true\n
       
      mockery will dynamically discover all sub-packages within the specified package. This is done by calling packages.Load on the specified package, which induces Go to download the package from the internet (or simply your local project). Mockery then recursively discovers all sub-directories from the root package that also contain .go files and injects the respective package path into the config map as if you had specified them manually. As an example, your in-memory config map may end up looking like this:
       YAML
      packages:\n  github.com/user/project:\n    config:\n      recursive: true\n      with-expecter: true\n  github.com/user/project/subpkg1:\n    config:\n      recursive: true\n      with-expecter: true\n  github.com/user/project/subpkg2:\n    config:\n      recursive: true\n      with-expecter: true\n
       
      You can use the showconfig command to see the config mockery injects. The output of showconfig theoretically could be copy-pasted into your YAML file as it is semantically equivalent.
       
      mockery will not recurse into submodules, i.e. any subdirectory that contains a go.mod file. You must specify the submodule as a separate line item in the config if you would like mocks generated for it as well.
       performance characteristics 
      The performance when using recursive: true may be worse than manually specifying all packages statically in the YAML file. This is because of the fact that mockery has to recursively walk the filesystem path that contains the package in question. It may unnecessarily walk down unrelated paths (for example, a Python virtual environment that is in the same path as your package). For this reason, it is recommended not to use recursive: true if it can be avoided.

       v2.10.0 \u00b7 with-expecter: True
       
      Mockery now supports an \"expecter\" struct, which allows your tests to use type-safe methods to generate call expectations. When enabled through the with-expecter: True mockery configuration, you can enter into the expecter interface by simply calling .EXPECT() on your mock object.
       
      For example, given an interface such as Go
      type Requester interface {\n    Get(path string) (string, error)\n}\n
       
      You can use the expecter interface as such: Go
      requesterMock := mocks.NewRequester(t)\nrequesterMock.EXPECT().Get(\"some path\").Return(\"result\", nil)\n
       
      A RunAndReturn method is also available on the expecter struct that allows you to dynamically set a return value based on the input to the mock's call.
       Go
      requesterMock.EXPECT().\n    Get(mock.Anything).\n    RunAndReturn(func(path string) (string, error) { \n        fmt.Println(path, \"was called\")\n        return (\"result for \" + path), nil\n    })\n
       
      Note
       
      Note that the types of the arguments on the EXPECT methods are interface{}, not the actual type of your interface. The reason for this is that you may want to pass mock.Any as an argument, which means that the argument you pass may be an arbitrary type. The types are still provided in the expecter method docstrings.

      Return Value Providers can be used one of two ways. You may either define a single function with the exact same signature (number and type of input and return parameters) and pass that as a single value to Return, or you may pass multiple values to Return (one for each return parameter of the mocked function.)  If you are using the second form, for each of the return values of the mocked function, Return needs a function which takes the same arguments as the mocked function, and returns one of the return values. For example, if the return argument signature of passthrough in the above example was instead (string, error) in the interface, Return would also need a second function argument to define the error value:
       Go
      type Proxy interface {\npassthrough(ctx context.Context, s string) (string, error)\n}\n

      "},{"location":"migrating_to_packages/#background","title":"Background","text":"
      mockery was built during the pre-module era of Golang. Much of its codebase and configuration syntax was designed around file-based operations. This model became highly inefficient once Golang migrated to module-based packages. The old configuration semantics also proved limiting -- many users introduced and requested feature additions to mockery to support esoteric use-cases. This proved to be a huge maintenance burden that existed solely because the configuration model could not flexibly describe all the situations users wanted. The packages semantics provides us a few highly desirable traits:
       
         
      1. Orders of magnitude performance increase, due to calling packages.Load once or twice for an entire project, versus once per file in the legacy semantics.
        2.  
      2. Hierarchical configuration model that allows interface-specific config to be inherited from package-level config, which is inherited from defaults.
        3.  
      3. Single configuration file that describes the entirety of mockery's behavior, instead of spread out by //go:generate statements.
        4.  
      4. Extensive and flexible usage of a Golang string templating environment that allows users to dynamically specify parameter values.

      The existence of the packages: map in your configuration acts as a feature flag that enables the feature.
       
      The configuration parameters used in packages should be considered to have no relation to their meanings in the legacy scheme. It is recommended to wipe out all previous configuration and command-line parameters previously used.
       
      The configuration docs show the parameters that are available for use in the packages scheme. You should only use the parameters shown in this section. Mockery will not prevent you from using the legacy parameter set, but doing so will result in undefined behavior.
       
      All of the parameters in the config section can be specified at the top level of the config file, which serves as the default values. The packages config section defines package-specific config. See some examples here.

      Take for example a configuration where you are specifying all: true at the top of your repo, and you're placing your mocks in a separate mocks/ directory, mirroring the directory structure of your original repo.
       YAML

      1. The use of replaceAll is a trick that is done to ensure mocks created for internal packages can be imported outside the mock directory. This retains the behavior of the legacy config.
        2.  
       
      While the example config provided here is more verbose, that is because we're specifying many non-default values in order to retain strict equivalence for this example. It's recommended to refer to the configuration parameters to see the defaults provided.

      Previously, the recommended way of generating mocks was to call mockery once per interface using //go:generate. Generating interface-specific mocks this way is no longer supported. You may still use //go:generate to call mockery, however it will generate all interfaces defined in your config file. There currently exists no semantics to specify the generation of specific interfaces from the command line (not because we reject the idea, but because it was not seen as a requirement for the initial iteration of packages).

      The legacy behavior iterated over every .go file in your project, called packages.Load to parse the syntax tree, and generated mocks for every interface found in the file. The new behavior instead simply grabs the list of packages to load from the config file, or in the case of recursive: True, walks the file-system tree to discover the packages that exist (without actually parsing the files). Using this list, it calls packages.Load once with the list of packages that were discovered.

      When using the packages feature, recursive: true and you have specified a package that contains no *.go files, mockery is unable to determine the on-disk location of the package in order to continue the recursive package search. This appears to be a limitation of the golang.org/x/tools/go/packages package that is used to parse package metadata.
       
      The solution is to create a .go file in the package's path and add a package [name] directive at the top. It doesn't matter what the file is called. This allows mockery to properly read package metadata.

      1. Update to the latest go version
        2.

      Additionally, this issue only happens when compiling mockery from source, such as with go install. Our docs recommend not to use go install as the success of your build depends on the compatibility of your Go version with the semantics in use. You would not encounter this issue if using one of the installation methods that install pre-built binaries, like downloading the .tar.gz binaries, or through brew install.

      There might be instances where you want a mock to return different values on successive calls that provide the same arguments. For example, we might want to test this behavior:
       Go
      // Return \"foo\" on the first call\ngetter := NewGetter()\nassert(t, \"foo\", getter.Get(\"key\"))\n\n// Return \"bar\" on the second call\nassert(t, \"bar\", getter.Get(\"key\"))\n
       
      This can be done by using the .Once() method on the mock call expectation:
       Go
      mockGetter := NewMockGetter(t)\nmockGetter.EXPECT().Get(mock.anything).Return(\"foo\").Once()\nmockGetter.EXPECT().Get(mock.anything).Return(\"bar\").Once()\n
       
      Or you can identify an arbitrary number of times each value should be returned:
       Go
      mockGetter := NewMockGetter(t)\nmockGetter.EXPECT().Get(mock.anything).Return(\"foo\").Times(4)\nmockGetter.EXPECT().Get(mock.anything).Return(\"bar\").Times(2)\n

      Consider if we have a function func Bar(message ...string) error. A typical assertion might look like this:
       Go
      func TestFoo(t *testing.T) {\n  m := NewMockFoo(t)\n  m.On(\"Bar\", \"hello\", \"world\").Return(nil)\n
       
      We might also want to make an assertion that says \"any number of variadic arguments\":
       Go
      m.On(\"Bar\", mock.Anything).Return(nil)\n
       
      However, what we've given to mockery is ambiguous because it is impossible to distinguish between these two intentions:
       
         
      1. Any number of variadic arguments of any value
        2.  
      2. A single variadic argument of any value
        3.  
       
      This is fixed in #359 where you can provide unroll-variadic: False to get back to the old behavior. Thus, if you want to assert (1), you can then do:
       Go
      m.On(\"Bar\", mock.Anything).Return(nil)\n
       
      If you want to assert (2), you must set unroll-variadic: True. Then this assertion's intention will be modified to mean the second case:
       Go
      m.On(\"Bar\", mock.Anything).Return(nil)\n
       
      An upstream patch to testify is currently underway to allow passing mock.Anything directly to the variadic slice: https://github.com/stretchr/testify/pull/1348
       
      If this is merged, it would become possible to describe the above two cases respectively:
       Go
      // case 1\nm.On(\"Bar\", mock.Anything).Return(nil)\n// case 2\nm.On(\"Bar\", []interface{}{mock.Anything}).Return(nil)\n

      mockery uses the viper package for configuration mapping and parsing. Viper is set to automatically search for all config variables specified in its config struct. One of the config variables is named version, which gets mapped to an environment variable called MOCKERY_VERSION. If you set this environment variable, mockery attempts to parse it into the version bool config.
