Signature de la fonction raises

def raises(*args) 

Description

raises.__doc__

Decorator to check for raised exceptions.

    The decorated test function must raise one of the passed exceptions to
    pass.  If you want to test many assertions about exceptions in a single
    test, you may want to use `assert_raises` instead.

    .. warning::
       This decorator is nose specific, do not use it if you are using a
       different test framework.

    Parameters
    ----------
    args : exceptions
        The test passes if any of the passed exceptions is raised.

    Raises
    ------
    AssertionError

    Examples
    --------

    Usage::

        @raises(TypeError, ValueError)
        def test_raises_type_error():
            raise TypeError("This test passes")

        @raises(Exception)
        def test_that_fails_by_passing():
            pass
