这在进行彻底的代码测试时很有效,在所有的assert都通过了后,只需要加上标志就能发行一个优化的版本——当标志启用时,__debug__变量将置False,并且取消所有assert条件的判断。但这个功能也可能造成麻烦,如果你依赖assert但又没有发现他们消失的时候。 What is the use of assert in Python? Hosseinasked: I have ...

self.assertFalse(os.path.isfile(self.tmpfilepath), "Failed to remove the file.") Our test case is pretty simple, but every time it is run, a temporary file is created and then deleted. Additionally, we have no way of testing whether ourrmmethod properly passes the argument down to the...
