PHPUnit on Apache – how to capture “console” output?

I’m implementing the server API (for geni.com) in PHP. The server requires OAuth authentication, so I need a browser because this requires user input (to permit access to their account). THIS all works fine.

Now I want to use PHPUnit to test the whole thing. My index.php calls the testsuite, and I THINK the tests are running (no errors in log, and it continues running past the call). Obviously there is no console for the output.

So HOW can I capture the test results?
