Testing from 0 to 100
summary
Workshop walks from zero to a working test pipeline: mocha and chai for unit tests, Pokedex with 151 Pokémon seeded via knex migrations for API tests, asynchronous tests using promises and callbacks, and end‑to‑end checks with webdriverIO/selenium (local or ngrok) that run in seconds. Snapshot checks use Jest snapshot testing, visual regression uses Applitools visual diffs that flag a CSS change. Exercises show migrations, clean setup/teardown, tests failing then passing after fixes — the examples actually run and catch real bugs.
