- rename TestController.createRunConfiguration to .createRunProfile, and associated types
- rename TestItemCollection.remove to TestItemCollection.delete
This changeset results from the discussion in and fixes#126987.
Migration for these changes should take about 15-20 minutes.
- `createTestItem` no longer takes a parent. Instead, it creates a free-
floating test item, which can be added as a child of a parent.
- The `TestItem.children` is now a `TestItemCollection`, a set-like
interface that also allows replacing items (intelligently diffing
them internally) wholesale. This removes the need for the "generation
counter" used in samples previously.
- There is no longer a `root` on the test controller, but instead an
`items` property which is the same `TestItemCollection`
- The `tests` in the `TestRunRequest` has been replaced with an `include`
property. If undefined, the extension should run all tests. (Since
there is no longer a root to reference).
Here's some example migrations:

- 3aff746316
Data was viral and spread generics all over the place. It was also
hard to type correctly and consistently, which ended up in the type
being `any` unless great care was taken.
This removes the `data`. Instead, consumers can use a `WeakMap<TestItem, T>`
to keep data associated with the test item. This is a similar pattern
to what is used to store data about documents and debug sessions, for
example. Here's an example of a migration:
8fdf822985 (diff-2fe3ad6ad19447c57c5db14c5a6ccb5544944494db6b909540d70ea499784b49R9)
Previously in the testing API, you called `registerTestProvider` with
your own instance of a TestController, and VS Code would request
workspace or document tests. This has been changed: now, you call
`createTestController`, which returns an object, and call
`createTestItem` to insert test nodes under the `controller.root`.
Extensions should generally decide themselves when to publish tests. For
example, when a file is opened in an editor, test extensions will want
to make sure tests for that file are available so that inline
decorations can be shown. This is pretty similar to what the editor
API does in diagnostics.
There is still a `resolveChildrenHandler` on the controller (rather than
the TestItem directly), which you should _set_ if the test extension
supports lazy discovery. Additionally, if you support running tests,
you'll also want a `runHandler` (migrating from the old `runTests` method).
Some of the existing test providers have been updated, you can check
them out here:
- https://github.com/microsoft/vscode-extension-samples/tree/main/test-provider-sample
- https://github.com/microsoft/vscode-selfhost-test-provider
In summary, to update to the new API:
- Call `vscode.test.createTestController` instead of `registerTestController`
- Move the contents of your `runTests` method to `controller.runHandler`
- Move your `TestItem.resolveHandler` to `controller.resolveChildrenHandler`,
which may involve adding some `instanceof` checks.
- If you lazily discovered tests in `createDocumentTestRoot`, you'll want
to trigger that logic based on `vscode.workspace.onDidOpenTextDocument`.
- If your test runner can deal with showing locations of unsaved changes,
listen for `vscode.workspace.onDidChangeTextDocument` to trigger those
changes in the tree.
For #120675
This uses a script to add the override keyword to places that need it in the codebase
Note that we can't enable the --noImplicitOverride setting yet since there are still around 200 errors that require further attention
