feat(vscode): support run tests with debug or coverage, list test items in tree structure by claneo · Pull Request #738 · web-infra-dev/rstest

claneo · 2025-12-05T12:32:09Z

depends on #720

New Features

Better test list view
1. Display test items in a tree structure instead of the previous flat list
2. Hide the workspace node if there's only one workspace open
3. Hide the project node if there's only one project and it is placed at the root of the workspace
Spawn a separate worker every time the test is run
1. Support debugging tests by starting the worker with the --inspect-wait argument
2. Support test run cancellation by killing the worker
Support running tests with coverage
Use the capabilities of rstest itself to execute multiple test files in parallel
The test files scan result is exactly the same as rstest. Now the extension reads include/exclude from the config file, scans with tinyglobby, then watches changes with the VSCode watcher, and filters files with picomatch

Pull request overview

This PR significantly enhances the VSCode extension by adding test debugging and coverage support, improving the test tree visualization, and refactoring the test execution architecture to use separate worker processes for each test run.

Key changes:

Implements debug and coverage run profiles for tests, enabling developers to debug tests and collect coverage information directly from VS Code
Restructures the test item tree to hide workspace/project nodes when there's only one, providing a cleaner UI
Replaces the long-lived worker process with ephemeral workers spawned per test run, enabling test cancellation and better isolation

cc @9aoy , coverage reporter now can accept an instance, i think it's nice to have that. PTAL.
