无法在Pycharm中调试unittes

Question

我在pycharm中调试单元测试时遇到问题。我可以使用我的配置运行它们，但是当我运行调试器时，我得到以下错误输出：

Error

FileNotFoundError: [Errno 2] No such file or directory: 'pydevd_attach_to_process'

我的目录结构是：

我的unittest配置是：

tests/test_setup_script.py看起来像：

import unittest
import os
import setup # the path to this file is scheduler/setup.py. This import may be breaking things


class TestSetupScript(unittest.TestCase):


    def test_load_db_connection_valid_yaml_file(self):
        file_name = "valid-yaml.yml"
        with open(file_name, 'w') as file:
            file.write("""
            test:
                hello world
                a = b
                """)

        yaml = setup.load_yaml_configuration(file_name)
        # I want to debug the line above, hence no assertions here

pydevd_attach_to_process做了什么以及如何确保在调试过程中找到它？问题实际上与找到的文件/目录无关吗？

Answer 1

实际上，失败的原因是代码中的“导入设置”导入了安装模块，该模块是PyCharm调试器运行时的一部分，而不是您自己的安装模块。最简单的解决方法是将setup.py文件重命名为其他内容，并相应地更新代码中的导入。
