Learn Testing

Test-driven development, or TDD, is the practice of writing your tests firsts, then using those tests to guide you as you write your actual production code. This may sound crazy, but it turns out that it makes writing code much easier. It provides a clear workflow and next steps while you're building and has the added benefit of producing a test suite you can have confidence in. With these courses and videos we'll teach you everything you need to know to get started with TDD.
