- Allow coverage bar color thresholds to be configurable as the Java
folks requested.
- Update some of our scripts for integration into
the selfhost test runner.
- Initial parts of showing function coverage in the Test Coverage view.
(Still a work in progress, more tomorrow)
* snippet completions should also check with the completion model
this will allow to return "more" from the snippet completion item provider and rely on the completions model to do some filtering
* when debugging tests allow to use console.log
* fix https://github.com/microsoft/vscode/issues/191070
This adds an `assertHeap` function that can be used in tests. It
takes a heap snapshot, and asserts the state of classes in memory. This
works in Node and the Electron sandbox, but is a no-op in the browser.
Snapshots are process asynchronously and will report failures at the end
of the suite.
This method should be used sparingly (e.g. once at the end of a suite to
ensure nothing leaked before), as gathering a heap snapshot is fairly
slow, at least until V8 11.5.130 (https://v8.dev/blog/speeding-up-v8-heap-snapshots).
When used, the function will ensure the test has a minimum timeout
duration of 20s to avoid immediate failures.
It takes options containing a mapping of class names, and assertion functions
to run on the number of retained instances of that class. For example:
```ts
assertSnapshot({
classes: {
ShouldNeverLeak: count => assert.strictEqual(count, 0),
SomeSingleton: count => assert(count <= 1),
}
});
```

* eng: onboard to the extension test runner
Adds a `.vscode-test.js` file that uses the new extension test CLI to
run tests. Also, onboards the markdown-language-features as the first
built-in extension to use it.
With the `ms-vscode.extension-test-runner` extension installed, the
markdown-language-features' tests can be run and debugged easily in
the UI :)
* fixup
Second attempt at this, which should work. Stop trying to use
exposeFunction, which seems to work poorly on macOS webkit in CI, and
just run a server with HTTP endpoints to do the "RPC."
Reuses Alex's "yaserver" module that we were already using for other
tests. Uses a secure random prefix for security in each run.
Should fix the issue that @roblourens and @Yoyokrazy were hitting with snapshot tests on macOS WebKit in CI. Not pretty, but I'd rather do this than spend a bunch of time chasing down something that certainly seems to be a browser issue.
