Write unit, integration, E2E, load, and accessibility tests; debug fixtures, mocks, coverage, and flaky suites.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Testing: Write Tests That Catch Real Bugs

Write, structure, and maintain tests across unit, integration, E2E, accessibility, and performance layers. The goal is tests that catch regressions, document behavior, and run fast in CI - not tests that exist to inflate coverage numbers.

**Target versions** (October 2026):
- Vitest **5.0.5**, Jest **30.5.2**
- Playwright **1.64.1**, Cypress **16.1.1** (both Vitest and Cypress are major upgrades; review migration notes)
- pytest **9.2.0**, pytest-cov **7.1.0**
- Go **1.27.3** (testing stdlib, `testing/synctest` GA)
- Rust **1.99.0** (`cargo test`, cargo-nextest **0.9.150**)
- Testing Library **16.3.3** (`@testing-library/react`)
- axe-core **4.14.0** (`@axe-core/playwright`)
- Grafana k6 **2.3.0**

How to install

The exact contents, by fingerprint
mdr add iuliandita/skills/testing@sha256:890340d409f1d890

The line at the top of this page pins the label git:20261028.6d7fe56, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
