“A programmer is an organism capable of converting coffee into code.” The best excuse for a 5-minute coffee break used to be “my code is compiling,” and these days we have “my tests are running.” It's a huge waste of developer time and continuous integration resources to have such long-running tests. But what’s even more important, it slows down development and deployment velocity, resulting in slower time to market and greater lead times. Join this session for a smart solution to this problem. We’ll show you how a new Java™ tool can drastically reduce your test execution time, letting you stay in the zone and increasing your personal productivity and velocity. Caveat: You may have to find a different excuse to get coffee.
