I would like to try and implement some TDD in our web applications to reduce regressions and improve release quality, but I'm not convinced at how well automated testing can perform with something as fluffy as web applications.
I've read about and tried TDD and unit testing, but the examples are 'solid' and rather simple functionalities like currency converters, and so on.
Are there any resources that can help with unit testing content management and publication systems? How about unit testing a shopping cart/store (physical and online products)? AJAX?
Googling for "Web Test Driven Development" just gets me old articles from several years ago either covering the same examples of calculator-like function or discussions about why TDD is better than anything (without any examples).
