Back in 2014 I wrote a blog post listing three mistakes often made by folks who are new to test-driven development (TDD). We’re doing TDD, but we have no code to test; we have nothing to hang our first test on, so we need to invent something, fast! The three mistakes I identified are: Starting with error cases or null cases.
