v0.4.0 Beta 2

Since v0.4.0 is going to be a larger release, we're starting with a short series of beta releases.

Changes

• Global
  • Renamed ensurepkg to ensurer and ensurepkg.Ensure to ensurer.E in a backwards compatible way. ensurepkg is marked as deprecated, and you are encourage to find and replace all references at your earliest convenience. ensurepkg may be removed in an upcoming release.
• ensure.RunTableByIndex:
  • The underlying implementation was refactored from the ground up to make it much more extensible and testable in the future
  • Mocks can be completely ignored using the `ensure:"-"` tag, in addition to the existing `ensure:"ignoreunused"` tag for making them optional
  • ⚠️ Breaking Change: Unused mocks are now an error unless they are ignored (`ensure:"-"`) or optional (`ensure:"ignoreunused"`)
  • Warnings are no longer issued, since unused mocks are now an error
  • Supports embedded pointer fields in structs and mocks instead of only embedded non-pointer fields
  • Correctly handles "shadowed" fields in embedded fields in both Subject and Mocks
  • Duplicate mocks are now supported, but will cause errors when matching a Subject, unless one of them is ignored (`ensure:"-"`) or optional (`ensure:"ignoreunused"`)
