单元测试不起作用，因为导入的文件作为输入

Question

我有一个项目作为实际结构：

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

我想使我的设置自动化，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 30 个导入，但随后我有输入：

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，当我像这样在我的 testExample.py 中导入安装程序时

from setup import *

我进行单元测试，我收到此错误消息

是的，错误get_input，只是因为我尝试用返回名为 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，但我认为我不应该这样做，我不是在尝试测试输入，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，它会启动它！我尝试在基本函数中导入，它运行设置代码...这可能就是 unitest 不起作用的原因。我会尝试解决它并返回答案。

问题已解决。

简单而漂亮地，python中有一行告诉代码只有在直接启动时才运行。

if __name__ == "__main__"

我相信该文件是启动时给出的固有__name__，并且只有在直接启动时才会"__main__"此名称。因此，我可以导入设置，而不会遇到麻烦，让它在我的脸上启动并弄乱我的代码和测试。

日安！
