Two setUp() functions in python unit testing, one that runs for every test, one that only runs once

Question

我刚刚开始使用单元测试，我想为每个测试运行一些代码（这就是默认的setUp（）看起来如何工作），但是我想让一些代码在运行开始时只运行一次？

Answer 1

Answer 2

You can use setUpClass which runs once to set up the test class. It runs before the test methods in that class are executed:

@classmethod
def setUpClass(cls):
