Testing2
Unit tests, integration tests, UI layer tests - it won’t come as a surprise that we ❤️ testing at CircleCI. Improving your tests, whether learning something new about TDD, or fixing flaky tests, will improve the entire CI process and make software delivery smoother, faster, and more predictable.
