Signals to nose that this function is or is not a test.
If True, specifies that the decorated callable is a test. If False, specifies that the decorated callable is not a test. Default is True.
This decorator can’t use the nose namespace, because it can be
called from a non-test module. See also
setastest can be used in the following way:
from numpy.testing import dec @dec.setastest(False) def func_with_test_in_name(arg1, arg2): pass
