assert_raises
(exception_class, callable, *args, **kwargs)[source]¶ 失败,除非在使用参数args和关键字参数kwargs调用时,callable抛出类exception_class的异常。如果抛出不同类型的异常,它不会被捕获,并且测试用例将被视为已经遭遇错误,正如异常意外。
或者,
assert_raises
可用作上下文管理器:>>> from numpy.testing import assert_raises >>> with assert_raises(ZeroDivisionError): ... 1 / 0
相当于
>>> def div(x, y): ... return x / y >>> assert_raises(ZeroDivisionError, div, 1, 0)
