单元测试不起作用，因为导入的文件作为输入

Question

我有一个实际结构的项目：

Project
   |-setup.py
   |
   |-Code
   |  |-exemple.py
   |
   |-Test
      |-testExemple.py

我想让我的设置自动化以设置文件和路径目录，无论它们是什么。所以在我的 Setup.py 中，我有大约 30 个导入，但是我有输入：

testFolderNameSetup = input("Enter the name of the folder containing your tests:")
testFolderNameSetup = "./" + str(testFolderNameSetup)
testFolderPathNameSetup = (os.path.abspath(os.path.join(os.path.dirname(__file__), testFolderNameSetup)))

if os.path.exists(testFolderPathNameSetup):
     sys.path.insert(0, testFolderPathNameSetup)

问题是，当我像这样在 testExample.py 中导入设置时

from setup import *

我启动了单元测试，但收到此错误消息

是的，错误是 get_input，只是因为我尝试用一个返回名为 get_input 的输入的函数替换输入，但它仍然不起作用。我听说过模拟输入，但我认为我不应该那样做，我不是要测试输入，我只是想导入一个在其脚本中使用输入的文件...

如果有人知道如何解决这个问题，请帮忙！

谢谢！

似乎当我导入 setup.py 时，它启动了！我尝试导入一个基本函数，它运行设置代码……这可能就是 unitest 不起作用的原因。我会尝试解决并返回答案。

问题已解决。

简单而漂亮，python 中有一行代码告诉运行仅当它直接启动时。

if __name__ == "__main__"

我认为该文件作为固有 __name__ 是在启动时给出的，并且此名称仅在直接启动时才为 "__main__"。因此，我可以导入设置，而不会遇到它在我面前启动并弄乱我的代码和测试的麻烦。

美好的一天！

unittesting doesn't work because an imported file as inputs
