/test or /test all	Every group below except gpu, at the same time
/test python	The quick tests.
/test slow	The tests marked slow
/test gpu	The tests marked gpu, on the project GPU machine
/test web	The 3D visualizer

Anything after the group name is passed to pytest, so /test python -k sampler
runs the quick tests whose names contain "sampler".

These commands are for tests that are too slow or need hardware to run every time.
