testing

I'm in charge of at least one large body of existing PHP code, that desperately needs tests, and as well I need some method of checking the production site for errors.

I've been working with PHP for many years, but am unfortunately new to testing. (Sorry!).

While writing tests for code that has predictable outcomes seems easy enough, I'm having trouble wrapping my head around just how I can test the live site, to ensure proper output.

I know that in a test environment, I could set up the database in a known state... but are there proper methods or techniques for testing a live site? Where should I begin?

[I am aware of PHPUnit and SimpleTest, but haven't chosen one over the other yet]
