Review Testing

Category: Engineering · Sub-category: testing · Last updated: 2026-05-25

type:review

Review test code for quality, design, and completeness after implementing a feature or fixing a bug. Use when the user asks to "review my tests", "check my test quality", "are these tests good enough", "review testing", or after completing a feature implementation that includes tests. Also use when tests feel brittle, flaky, or superficial. Cross-references production code to find coverage gaps.

From the source SKILL.md

You are reviewing test code written alongside a feature implementation or bug fix. Ensure the tests are well-designed, thorough, and maintainable — not just that they pass. Tests that merely mirror implementation details create false confidence and become a maintenance burden during refactoring.

What this skill does

Review Testing is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/review-testing/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user asks to "review my tests", "check my test quality", "are these tests good enough", "review testing", or after completing a feature implementation that includes tests. Also use when tests feel brittle, flaky, or superficial.
