What you'll learn

Both new and seasoned developers, especially solo practitioners, can have a lot of misconceptions about test-driven development (TDD). The primary misconceptions are: "It's extra work, it's extra code, I can't ship tests, why would I test something simple and obvious." Magic happens when the light bulb switches to "on." In this session, Paul Roub will walk through the design of a simple-enough class, showing along the way how initial assumptions are often wrong, how to avoid making those assumptions too early, how to throw away less code, and how to feel comfortable and safe when you do throw away code.
