Summary Jean Paul Boodhoo gets real with TDD in this the first ofa two-part series on TDD.

One of the most popular of these if called FIT, created by W...

Summary Writing a test makes you clarify your ideas about what needs to be done, and making the test pass means that you know that you've added a little more functionality today. Having a comprehensive suite of tests gives you the confidence to get on with things because you can tell when you've broken the system, and tests that are difficult to write show you where you need to improve. Bio Ste...

Google Tech Talks January, 7 2008 ABSTRACT Modern software pervasively uses structurally complex data, for example web-traversal code operates on graphs that encode web pages, and IDEs manipulate program representations such as abstract syntax trees. The standard approach to generating test suites for such software, manual generation of the inputs in the suite, is tedious and error-prone. This ...
