Agent skill
integration-tests
Use when running integration tests in the VS Code repo. Covers scripts/test-integration.sh (macOS/Linux) and scripts/test-integration.bat (Windows), their supported arguments for filtering, and the difference between node.js integration tests and extension host tests.

SKILL.md
Running Integration Tests
Integration tests in VS Code are split into two categories:
- Node.js integration tests - files ending in
.integrationTest.tsundersrc/. These run in Electron via the same Mocha runner as unit tests. - Extension host tests - tests embedded in built-in extensions under
extensions/(API tests, Git tests, TypeScript tests, etc.). These launch a full VS Code instance with--extensionDevelopmentPath.
Scripts
- macOS / Linux:
./scripts/test-integration.sh [options] - Windows:
.\scripts\test-integration.bat [options]
When run without filters, both scripts execute all node.js integration tests followed by all extension host tests.
When run with --run or --runGlob (without --suite), only the node.js integration tests are run and the filter is applied. Extension host tests are skipped since these filters are node.js-specific.
When run with --grep alone (no --run, --runGlob, or --suite), all tests are run -- both node.js integration tests and all extension host suites -- with the grep pattern forwarded to every test runner.
When run with --suite, only the matching extension host test suites are run. Node.js integration tests are skipped. Combine --suite with --grep to filter individual tests within the selected suites.
Options
--run <file> - Run tests from a specific file
Accepts a source file path (starting with src/). Works identically to scripts/test.sh --run.
./scripts/test-integration.sh --run src/vs/workbench/services/search/test/browser/search.integrationTest.ts
--runGlob <pattern> (aliases: --glob, --runGrep) - Select test files by path
Selects which test files to load by matching compiled .js file paths against a glob pattern. Overrides the default **/*.integrationTest.js glob. Only applies to node.js integration tests (extension host tests are skipped).
./scripts/test-integration.sh --runGlob "**/search/**/*.integrationTest.js"
--grep <pattern> (aliases: -g, -f) - Filter test cases by name
Filters which test cases run by matching against their test titles (e.g. describe/test names). When used alone, the grep is applied to both node.js integration tests and all extension host suites. When combined with --suite, only the matched suites run with the grep.
./scripts/test-integration.sh --grep "TextSearchProvider"
--suite <pattern> - Run specific extension host test suites
Runs only the extension host test suites whose name matches the pattern. Supports comma-separated values and shell glob patterns (on macOS/Linux). Node.js integration tests are skipped.
Available suite names: api-folder, api-workspace, colorize, terminal-suggest, typescript, markdown, emmet, git, git-base, ipynb, notebook-renderers, configuration-editing, github-authentication, css, html.
# Run only Git extension tests
./scripts/test-integration.sh --suite git
# Run API folder and workspace tests (glob, macOS/Linux only)
./scripts/test-integration.sh --suite 'api*'
# Run multiple specific suites
./scripts/test-integration.sh --suite 'git,emmet,typescript'
# Filter tests within a suite by name
./scripts/test-integration.sh --suite api-folder --grep 'should open'
--help, -h - Show help
./scripts/test-integration.sh --help
Other options
All other options (e.g. --timeout, --coverage, --reporter) are forwarded to the underlying scripts/test.sh runner for node.js integration tests. These extra options are not forwarded to extension host suites when using --suite.
Examples
# Run all integration tests (node.js + extension host)
./scripts/test-integration.sh
# Run a single integration test file
./scripts/test-integration.sh --run src/vs/workbench/services/search/test/browser/search.integrationTest.ts
# Run integration tests matching a grep pattern
./scripts/test-integration.sh --grep "TextSearchProvider"
# Run integration tests under a specific area
./scripts/test-integration.sh --runGlob "**/workbench/**/*.integrationTest.js"
# Run only Git extension host tests
./scripts/test-integration.sh --suite git
# Run API folder + workspace extension tests (glob)
./scripts/test-integration.sh --suite 'api*'
# Run multiple extension test suites
./scripts/test-integration.sh --suite 'git,typescript,emmet'
# Grep for specific tests in the API folder suite
./scripts/test-integration.sh --suite api-folder --grep 'should open'
# Combine file and grep
./scripts/test-integration.sh --run src/vs/workbench/services/search/test/browser/search.integrationTest.ts --grep "should search"
Compilation requirement
Tests run against compiled JavaScript output. Ensure the VS Code - Build watch task is running or that compilation has completed before running tests.
Distinction from unit tests
- Unit tests (
.test.ts) → usescripts/test.shor therunTeststool - Integration tests (
.integrationTest.tsand extension tests) → usescripts/test-integration.sh
Do not mix these up: scripts/test.sh will not find integration test files unless you explicitly pass --runGlob **/*.integrationTest.js, and scripts/test-integration.sh is not intended for .test.ts files.

component-fixtures
Use when creating or updating component fixtures for screenshot testing, or when designing UI components to be fixture-friendly. Covers fixture file structure, theming, service setup, CSS scoping, async rendering, and common pitfalls.
memory-leak-audit
Audit code for memory leaks and disposable issues. Use when reviewing event listeners, DOM handlers, lifecycle callbacks, or fixing leak reports. Covers addDisposableListener, Event.once, MutableDisposable, DisposableStore, and onWillDispose patterns.
fix-ci-failures
Investigate and fix CI failures on a pull request. Use when CI checks fail on a PR branch — covers finding the PR, identifying failed checks, downloading logs and artifacts, extracting the failure cause, and iterating on a fix. Requires the `gh` CLI.
