Root Cause

A test class uses a method like setup_method without defining it, or it is misspelled.

generic

中文

测试类使用了如 setup_method 的方法但未定义，或拼写错误。

Workarounds

  1. 95% success Define setup_method as class method 
    class TestClass:
    def setup_method(self):
        pass
  2. 90% success Use pytest fixture instead 
    @pytest.fixture(autouse=True)
def setup_method(self):
    pass

Dead Ends

Common approaches that don't work:

  1. Defining setup_method inside test function 70% fail

    setup_method should be a method of the test class, not nested inside a test.

  2. Using setup_method as a fixture 50% fail

    setup_method is a unittest convention; pytest uses fixtures instead.
