Running Integration Tests

Integration tests in VS Code are split into two categories:

1. Node.js integration tests - files ending in .integrationTest.ts under src/. These run in Electron via the same Mocha runner as unit tests.
2. 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
