One of the pillars for an agile process is the ability to inspect and adapt - see where you are and steer accordingly. As our products and projects – and their code base – grow bigger we face an increasing challenge to our ability as developers to see where we are. In particular, our suite of automated tests grows bigger and bigger and soon we are running thousands of tests. That's where the challenge lies: a *slow* build. Join this session to discuss ways of keeping those tests fast and see live demonstrations of techniques that help you keep your Ant or Maven build running quickly!
