Continuous Testing (CT) is a emerging developer practice that involves automatically running unit tests every time you change so much as a line of code. It gives you instant feedback about the semantic correctness of your code, just as modern IDE’s give you instant feedback about syntax errors. CT has a profound impact on the way we apply Test Driven Development.

In this talk, we'll demonstrate the use of a continuous test runner, and discuss the history, theory, practice, and daily application of CT to real-world projects.
