如果 name == 'main' 不适用于单元测试

Question

当我运行这段代码时：

from unittest import *


class TestSomething(TestCase):

    def test_thing(self):
        assert True


if __name__ == '__main__': main()

我收到属性错误：

我在 win32 上使用 Python 3.7.0b4（v3.7.0b4:eb96c37699，2018 年 5 月 2 日，19:02:22）[MSC v.1913 64 位 (AMD64)]。有人可以帮忙吗？

我无法解释原因，但如果我像下面那样更新您的代码，它会按预期工作。我只是按照文档示例 1:1 但使用了您的 class 代码。

import unittest

class TestSomething(unittest.TestCase):
    def test_thing(self):
        assert True


if __name__ == '__main__':
    unittest.main()

输出：

[zaphoxx]> uni.py

OK
