Running Unit Tests

Preferred: Use the runTests tool

If the runTests tool is available, prefer it over running shell commands. It provides structured output with detailed pass/fail information and supports filtering by file and test name.

• Pass absolute paths to test files via the files parameter.
• Pass test names via the testNames parameter to filter which tests run.
• Set mode="coverage" to collect coverage.

Example (conceptual): run tests in src/vs/editor/test/common/model.test.ts with test name filter "should split lines".

Fallback: Shell scripts

When the runTests tool is not available (e.g. in CLI environments), use the platform-appropriate script from the repo root:

• macOS / Linux: ./scripts/test.sh [options]
• Windows: .\scripts\test.bat [options]
