Python unittest - 与 assertRaises 相对? [英] Python unittest - opposite of assertRaises?

问题描述

我想编写一个测试来确定在给定情况下不会引发异常.

I want to write a test to establish that an Exception is not raised in a given circumstance.

测试是否引发异常很简单...

It's straightforward to test if an Exception is raised ...

sInvalidPath=AlwaysSuppliesAnInvalidPath()
self.assertRaises(PathIsNotAValidOne, MyObject, sInvalidPath) 

...但是你怎么能做到相反的.

... but how can you do the opposite.

我所追求的就是这样的东西......

Something like this i what I'm after ...

sValidPath=AlwaysSuppliesAValidPath()
self.assertNotRaises(PathIsNotAValidOne, MyObject, sValidPath) 

推荐答案

def run_test(self):
    try:
        myFunc()
    except ExceptionType:
        self.fail("myFunc() raised ExceptionType unexpectedly!")
