Jest Testing Expert

cin12211/orca-q
120 installs218 stars
Summary

This is your go-to when you need to write comprehensive Jest tests or debug tricky testing scenarios. It covers the full spectrum from basic config setup to the gnarly stuff like timer mocking, race condition handling, and custom matchers. The skill explicitly focuses on six areas: configuration, advanced mocking patterns, snapshot testing, async patterns, custom matchers, and performance optimization for CI. With 118 installs and passing security audits from Socket and Snyk, it's seen real use. Best for teams that already use Jest but want to level up their testing game or tackle those weird edge cases that make you want to skip writing tests altogether.
