numpy.testing.decorators.slow

numpy.testing.decorators.slow(t) [source]

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 consits of thousands of tests, so even a second is significant).

Parameters:	t : callable The test to label as slow.
Returns:	t : callable 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')
