# numpy.testing.decorators.slow

`numpy.testing.decorators.``slow`(t)

  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'
