"Test driven development (TDD) is emerging as one of the most successful developer productivity enhancing techniques to be recently discovered. The three-step: write test, write code, refactor – is a dance many of us are enjoying. This site is dedicated to promoting techniques, tools, and general good will in the test-driven community.

php|architect's Guide to PHP Design Patterns by Jason E. Sweat http://www.phparch.com/shop_product.php?itemid=96.
Design patterns often seen in php apps. Most (all?) classes are accompanied by unit tests which should help to give you an idea what tests look like. Also contains an appendix on SimpleTest testing practices.

Nice Test Forum

Here is a good link: http://www.agiledata.org/essays/tdd.html

You will find interesting articles on the theory and practice of software testing in the HTML archives of the Methods & Tools newsletter: http://www.methodsandtools.com/archive/archive.php

xUnit Test Patterns: Refactoring Test Code, started reading this book the other day, not even near finish, but I'm already willing to recommend it. Not PHP specific, no PHP code samples and PHPUnit is actually mention only in the Appendix. C# and Java seem to be the default in this book. However, the book isn't about the code but patterns, smells and other things you would rather not learn the hard way.

Something that's more an update. Simpletest now has a website over at:
http://www.simpletest.org

I'll have to look up Arawn's recommended book...

I have already read the ebook which arawn mentioned in his post - well its good for newbies but as mentioned by arawn you wont learn something entirely new in it.

a nice (and short) article describing TDD:

I just found this excellent "Guide to writing testable code": http://misko.hevery.com/2008/11/24/guid ... able-code/

And here is a PDF version of it: http://misko.hevery.com/attachments/Gui ... 20Code.pdf

Honestly it is really good, check it out.

"dont look for things, ask for things" ..... thats good right there

Model-Based Testing has been around for a few years. Check out a book by Mark Utting: Practical Model-Based Testing: A Tools Approach. A good example of such tool for testing web applications is TestOptimal (http://TestOptimal.com/).

It may seem hard to justify of spending time creating the system model, but if you look at the overall testing process, you actually gain efficiency at the end especially if you are in the agile development process which has a much shorter cycle and thus regression testing needs to be done a lot more often and your testing scripts need to be changed a lot frequently. You can find many literatures on Model-Based Testing on the internet or you can just go to http://TestOptimal.com/ in the support section, there are a few articles and presentations that cover the basics of Model-Based Testing.
