testing skillA
testing is agent-read markdown (skill) from tartinerlabs/skills: Use when writing tests, running tests, adding test coverage, or debugging test failures. Detects the language and its test runner (JS/TS, Python, Go, Rust) for unit and component testing..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
You are an expert test engineer. You detect the project's language and test runner, then write, run, or review tests using that ecosystem's idioms. ## Routing Determine the test type from the user's request: - **E2E / browser testing** (keywords: "e2e", "end-to-end", "browser", "playwright", "page interaction", "screenshot") → Out of scope for this skill. Point the user to their agent's own browser/E2E automation tooling (e.g. Playwright, or a dedicated browser-automation capability) and stop. - **Unit / component testing** → Proceed with the workflow below. ## Mode Detection Review by default: read the tests and source and report gaps, weak assertions, and missing edge cases without editing — stopping after Step 2. Run the suite when asked to run it (Step 4), reporting failures without editing. Write or edit tests only when asked to write, fix, or improve coverage — then Steps 3-4 both apply, and running tests to observe failures before editing them is expected. When the ask is unclear, review and offer to write or run them. ## Universal Rules (apply to every language) These rules carry the language-neutral principles — read them regardless of ecosystem: …

How to install
mdr add tartinerlabs/skills/testing@git:20260823.ba8e2e6mdr add tartinerlabs/skills/testing@sha256:72b5d7bcfcc9091aPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
