If you compete in the TopCoder SRMs, the TZTester plugin is very useful. It calls all the tests for you and displays the results, saving valuable minutes in the arena.
I used it with my old computer but couldn’t get it working on my new one, and with the clock counting down, sod’s law was against me.
$RUNTEST$ and $TESTCODE$ sat in my template, stubbornly refusing to become useful C++ code.
The solution was simple – I found it here.
Just make CodeProcessor your default editor, instead of (in my case) popsEdit.
