zudo-test-wisdom is Takazudo's frontend testing strategy guide for AI coding agents and the developers who review their work. It collects practical lessons from real projects to help you decide what to test and how to verify a change.
The guide covers six testing levels, from unit tests to AI-based visual verification as a last resort. Use the decision guide to choose the level a change needs, and the test integrity articles to spot flaky tests, false greens, and tests that merely agree with the implementation.
Install the test-wisdom Claude Code skill from this repository with pnpm setup:doc-skill, then use /test-wisdom <topic> to find relevant articles during development. The bundled verify-ui and headless-browser skills help check computed styles, screenshots, and browser interactions.
