Code Testing Generation Skill

MANDATORY ENTRY POINT for generating or writing tests. Invoke this skill before editing files whenever the user asks to generate tests, write/add unit tests, scaffold a test project or suite, improve/achieve coverage, extend an existing suite to cover an untested method, or test an app, API, service, module, library, or package. Applies to a single function, method or file as much as to a whole project — scope changes how much of the workflow runs, never whether the skill applies. Invoke it when the workspace looks sparse, gutted or partially deleted — then test only the source that remains and never restore missing source. Polyglot: C#/.NET, Python, TypeScript/JavaScript, Go, Rust, Java, Ruby. DO NOT USE FOR: running existing tests (use run-tests); analyzing coverage reports (use coverage-analysis or crap-score); MSTest-specific test authoring or modernization (use writing-mstest-tests).
