[Python-ideas] @unittest.skip_others decorator

[Jerry Seutter]

Hi, you may be interested in this.  It's part of the unittest module that
ships with Python:

=======================
./python.exe -m unittest test.test_call.CFunctionCalls.test_varargs0
.
----------------------------------------------------------------------
Ran 1 test in 0.000s

OK
=======================

An added bonus is that this works across many Python projects.

Hope this helps,

Jerry Seutter
