io.github.bluesky-social/atproto/testing

Testing practices for this monorepo — choosing between unit and end-to-end tests, where test files live, how tsconfig.test.json fits in, how to drive Playwright, to to write/adapt UI/end-to-end tests, and which test runner (vitest vs jest) to use. MUST be invoked BEFORE any code search or file reads whenever the user asks to add, write, or extend a test, add coverage, create a test file, set up testing in a new package, mentions vitest/jest, or refers to an existing `*.test.ts` file. Applies equally to unit tests and to end-to-end / UI tests — the skill routes to a Playwright-MCP-first discovery flow for the latter, which differs from normal code-search workflow.
