Embed unit, integration, and end-to-end tests into the delivery chain to validate code quality. Use this skill whenever the user mentions test integration, unit test, e2e test, test matrix, coverage gate, flaky test, test gate, or is working with Playwright, pytest, Jest, even if they never say "automated testing integration" explicitly. Operates entirely on context the agent already has. Do not use it for unrelated application feature work or general coding questions.
