numpy.testing.dec.slow#

testing.dec.slow(t)[source]#

Deprecated since version 1.21: This decorator is retained for compatibility with the nose testing framework, which is being phased out. Please use the nose2 or pytest frameworks instead.

Label a test as ‘slow’.

The exact definition of a slow test is obviously both subjective and hardware-dependent, but in general any individual test that requires more than a second or two should be labeled as slow (the whole suite consists of thousands of tests, so even a second is significant).

Parameters:

tcallable: The test to label as slow.

Returns:

tcallable: The decorated test t.

Examples

The numpy.testing module includes import decorators as dec. A test can be decorated as slow like this:

from numpy.testing import *

@dec.slow
def test_big(self):
    print('Big, slow test')
