Nice work Felix and Susanne, thanks!

No review yet, but a remark: As _GETset fiddles with global vars, the 
testcase should save those vars before running the testcases and recover 
them afterwards. This could be done in tearDown() and setUp(), an 
example can be found in 
tests/typo3/sysext/cms/tslib/tslib_content_testcase.php

Looking at the current _GETset I wonder why it doesn't simply take an 
input array and merges / overrides it to the server vars, maybe just to 
a specified subarray?

Regards
Christian
