Summary: <p>Episode 004: Testing</p> <h2>Summary</h2> <p>Sam Phippen, Justin Searls, and Noel Rappin spend this episode talking about the value of test-driven development (TDD) as well as its cost. They discuss the kinds of problems that developers are likely to have after they learn TDD and attempt to apply it to a large application. Learn why Rails is both great and terrible for automated testing, and how testing can influence the structure of your code.</p> <h2>Guests</h2> <p><a href="https://twitter.com/samphippen" rel="nofollow">Sam Phippen</a>: Engineer at <a href="https://www.digitalocean.com/" rel="nofollow">Digital Ocean</a> and member of the <a href="https://github.com/rspec" rel="nofollow">RSpec</a> Core Team</p> <p><a href="https://twitter.com/searls" rel="nofollow">Justin Searls</a>: Writes bad code effortlessly and cofounder of <a href="http://testdouble.com/" rel="nofollow">Test Double</a>.
