I follow the principle that you should test everything that could possibly fail. And I would like to have unit tests for everything; tests that exercise each small behavior in isolation. The components that are easiest to unit test are typically class and methods in plain object-oriented code. Not everything falls into that category, though. [...]

Uncle Bob (Robert C. Martin) has blogged about testing GUIs (web interfaces, that is; JSP and Rails) without having to run a web server.

I've been doing that on an ad hoc basis. Now Mike Naberezny has an interesting generalized class for wrapping PHP modules [...]

The problem is that it [Ravioli Code] tends to lead to functions (methods, etc.) without true coherence, and it often leaves the code to implement even something fairly simple scattered over a very large number of [...]

Tips for web testing
I just started listing the techniques I've learned when writing tests to exercise the web interface of a PHP application. This is from my experience and my personal preferences; it's not the final word or necessarily right for everyone.
The idea of being able to record and play back tests, as you can do with [...]
