This extension provides an extensible user interface for running your tests in VS Code. It can be used with any testing framework if there is a corresponding Test Adapter extension.
Other extensions can get full access to the Test Adapters by acting as Test Controllers.
The Test Explorer can also be used in VS Live Share sessions by installing the Test Explorer Live Share extension.
This extension will be automatically installed when you install one of the Test Adapters, so there is usually no need to install this extension manually.
In version 1.59, VS Code added an official API and UI for running tests, which provides all the functionality of this extension and more. Therefore this extension is now deprecated. I will keep maintaining it so it will remain usable but I don't plan to add any major new features to it.
Since version 2.22.0, this extension defaults to using VS Code's official testing UI. You can get the old Test Explorer UI back by setting testExplorer.useNativeTesting to false in your VS Code settings.
If you plan to write a new testing extension for VS Code, I recommend you use the native testing API as it's more flexible and has more features than this extension's Test Adapter API. Here's the official guide for the native testing API.
If you're maintaining an extension that uses the Test Adapter API, here is a short guide how to migrate your Test Adapter to the native API.
The migration isn't strictly necessary because this extension will remain usable and your users can switch to the native testing UI using the
testExplorer.useNativeTesting setting anyway, but you might find the additional flexibility of the native testing API useful in the future.
Currently the following Test Adapters are available:
- Mocha Test Explorer
- Jasmine Test Explorer
- Angular/Karma Test Explorer
- Jest Test Explorer
- AVA Test Explorer
- TestyTs Test Explorer
- React-scripts Test Adapter
- Ceedling Test Explorer
- CppUTest Test Explorer
- Unity Framework for C Test Explorer
- Acutest Test Explorer
- CMake Test Explorer
- CppUnitTestFramework Explorer
- Bandit Test Explorer
- CppUTest Test Explorer
- Boost.Test Explorer
- Acutest Test Explorer
- CppUnit Test Explorer
- The Test Explorer Live Share extension creates Test Adapters in Live Share guests that act as proxies for the Test Adapters in the Live Share host.
If there is no Test Adapter for your favorite testing framework yet, you can easily create your own.
Currently the following Test Controllers are available:
- The Test Explorer UI (which is the main part of this extension) is itself implemented as a Test Controller
- The Test Explorer Diagnostics Controller adds test results to the Problems panel in VS Code.
- The Test Explorer Status Bar extension provides information about the current test suite in the Status Bar.
- The Test Explorer Live Share extension creates Test Controllers in the Live Share host that act as proxies for the Test Explorers in the Live Share guests.
Do you have a new idea for interacting with the Test Adapters? You can easily get full access to all Test Adapters in your own extension by implementing your own controller.
The following configuration properties are available:
