Unit Testing with items that need to send headers

Question

I\'m currently working with PHPUnit to try and develop tests alongside what I\'m writing, however, I\'m currently working on writing the Session Manager, and am having issue

Answer 1

Can't you use output buffering before starting the test? If you buffer everything that is output, you shouldn't have problems setting any headers as no output would have yet been sent to client at that point.

Even if OB is used somewhere inside your classes, it is stackable and OB shouldn't affect what's going on inside.
