What are good online introductions to testing and Test Driven Development? [closed]

For the introduction to TDD, the bowling game episode is very nice, as it demonstrate how the tests drive the design. Then, here are tutorials focusing on C++ frameworks for CppUnit, Boot::Test and CppCheck.

To help choosing a framework, Noel LLopis explored this jungle, albeit a long time ago, especially it dosen't mention GoogleTest or you can refer to this question.

Oh, and BTW, [automated] unit testing and TDD can be applied even in non agile environment.

The wikipedia page is pretty good and has several useful links to both online and non-online resources of reasonably high quality, including an online tutorial. Once you have the basics, for C++ specific issues you could start with this presentation (PDF).

I wrote a series of blog postings several years ago about how I took some of my 'legacy' code without tests and first added tests to it and then reimplemented it from scratch in a TDD style. The idea was to show TDD and unit testing being used with a non trivial piece of code under test as I'd grown tired of seeing examples of testing simple code.

The code is C++ but it's for Windows so might not interest you, anyway, the articles kick off here: http://www.lenholgate.com/blog/2004/05/practical-testing.html
