在更新和一些项目导入之后，一些非常奇怪的事情发生在我的测试上，一旦从Pycharm运行。我已经修复了通用的单元测试运行器配置，但是我不能在运行单个测试时做到这一点，无论是在配置中还是仅仅用右键单击，这是相当舒适的。
非常简单的示例代码：

import unittest

class TestTheTester(unittest.TestCase):

    @classmethod
    def setUpClass(cls) -> None:
        cls.name = "TestTheTester"

    def test_unittest(self):
        self.assertEqual("TestTheTester", self.name)

从Shell运行它：

python3 -m unittest tests/test_the_tester.py 
.
----------------------------------------------------------------------
Ran 1 test in 0.000s

OK

从PyCharm运行，右键单击（选项"Run 'Python test in tests...'）：

/usr/bin/python3.8 /snap/pycharm-community/252/plugins/python-ce/helpers/pycharm/_jb_trialtest_runner.py --path /home/user123/development/Project456/tests/test_the_tester.py
Testing started at 10:26 ...
Launching trial with arguments --reporter=teamcity /home/user123/development/Project456/tests/test_the_tester.py in /home/user123/development/Project456/tests/

Error
Traceback (most recent call last):
Failure: builtins.tuple: (<class 'AttributeError'>, AttributeError("'TestTheTester' object has no attribute 'name'"), <traceback object at 0x7fc59e432f00>)

它创建的运行/调试配置为：

• “Python测试”之一
• 自动检测目标'Script path'到/home/user123/development/Project456/tests/test_the_tester.py
  *Python解释器Project Default（/usr/bin/python3.8）
  *工作目录/home/user123/development/Project456/tests/
• 两个选项'将内容根目录添加到PYTHONPATH'和'将源根目录添加到PUTHONPATH'均已选中
