In short, phpunit supresses STDOUT. It writes to STDERR by default, unless you add --verbose or --debug . You can do one of those things:

• var_dump your debug as usual but add a line ob_flush(); beneath it
• use the correct commands in phpunit for testing exactly what you're trying to test here

Obviously, the last thing is the Good Thing to do, and the rest are quick temporary hacks.
