Unit Tests

When you're working in the VS Code repository and need to run unit tests, this skill walks you through the runTests tool first, then falls back to the shell scripts (test.sh or test.bat) when necessary. It covers the practical stuff: passing file paths, filtering tests with grep, running globs, and collecting coverage. The guidance on bare file paths versus the explicit --run flag is helpful since the scripts accept both. One thing to note: these scripts only handle unit tests, not integration tests, and you need to have your build running or you'll be testing stale compiled output. It's a solid reference for the common flags and patterns without having to dig through script source code.
