In this new post to her blog Lorna Mitchell talks a bit about the upcoming TestFest event happening in Manchester next weekend and what she's learned about testing PHP to make things flow a bit smoother for her while there (and you, should you want to write tests in the future).
In preparation I decided it was high time to sit down and figure out what testing PHP is all about. People kept telling me it was easy but I had no clear picture of how all the pieces went together - there are different ways of doing the same thing and although I have been keen to get involved with testing for some time, I haven't been able to get started until now.
She looks at the automated tests as a part of the build ("make test") and some of the screens from the lcov testing results. She also recommends reading up on the phpt documentation to help you get going.
