Decorators that merely return a modified version of the original function
object are straightforward. Decorators that return a new function object need
to use nose.tools.make_decorator(original_function)(decorator) in returning the
decorator, in order to preserve metadata such as function name, setup and
teardown functions and so on - see nose.tools for more information.
This module provides a set of useful decorators meant to be ready to use in
your own tests. See the bottom of the file for the ready-made ones, and if you
find yourself writing a new one that may be of generic use, add it here.
Included decorators:
Lightweight testing that remains unittest-compatible.
- An @as_unittest decorator can be used to tag any normal parameter-less
function as a unittest TestCase. Then, both nose and normal unittest will
recognize it as such. This will make it easier to migrate away from Nose if
we ever need/want to while maintaining very lightweight tests.
NOTE: This file contains IPython-specific decorators. Using the machinery in
IPython.external.decorators, we import either numpy.testing.decorators if numpy is
available, OR use equivalent code in IPython.external._decorators, which
we've copied verbatim from numpy.

Parameters
----------
skip_condition : bool or callable
Flag to determine whether to skip test. If the condition is a
callable, it is used at runtime to dynamically make the decision. This
is useful for tests that may require costly imports, to delay the cost
until the test suite is actually executed.
msg : string
Message to give on raising a SkipTest exception.
Returns
-------
decorator : function
Decorator, which, when applied to a function, causes SkipTest
to be raised when the skip_condition was True, and the function
to be called normally otherwise.

Decorator, which, when applied to a function, causes SkipTest
to be raised, with the optional message added.

This is used to make a decorator to skip tests that require module to be
available, but delay the 'import numpy' to test execution time.
