Pycharm 从旧版本项目复制后无法识别项目包

Question

我正在尝试使用 pytest 为 repo 设置单元测试框架，并且我在一个旧分支中工作。我克隆了新分支并将文件复制到新分支。调用 pytest 时，测试会运行正常，但它们引用的是旧项目中的文件（即使它们是作为当前项目中的包导入的，而不是通过直接文件路径导入的）。

这是 line/command 用于运行 pytest:

(venv) C:\Program Files\Python-3.8.2\pycharm_projects\fnma-erm01-devl-edl-hao-repo_21.3>python -m pytest

为了尝试解决这个问题，我在本地删除了旧分支，现在 none 的测试可以运行，并且它不会将任何项目目录识别为有效模块。

pytest.ini 文件:

# pytest.ini
[pytest]
python_files = unittest_*.py

这是我已经知道的 tried/checked:

所有必要的文件夹都已标记为“Sources Root”。
我已将 __init__.py 添加到所有必要的文件夹中。
我已检查以确保 __init__.py 未被识别为文本文件。
我运行文件下的“使缓存无效/重新启动...”选项。
我已确保项目的解释器与当前项目和目录保持一致。

它不会让我包含屏幕截图，但项目结构应该不是问题，因为它在旧分支中运行得非常好。（旧分支结构与新分支结构完全相同，因此从一个复制到另一个时应该没有引用问题）

编辑 1：我正在使用 pytest.ini 配置文件，其中唯一指定的是用于识别测试文件的自定义前缀。我为新项目创建了一个新的 venv，并且我在 PyCharm 中从内置终端调用 pytest，因此 venv 处于活动状态。

编辑 2：缩短了堆栈跟踪以便于阅读，并添加了文件树和 pytest.ini 文件的相关部分。

Answer 1

好的，似乎 Pycharm 在复制到新项目后无法检测到源根中的更改，因为除了项目名称之外，路径是相同的。奇怪的是，如果我通过 Pycharm 的内置 pytest 运行ner 创建测试配置和运行，它就可以工作。也就是说，我无法让控制台使用正确的 PYTHONPATH，但我找到了解决方法。我没有使用 python -m pytest 通过控制台调用 pytest，而是创建了一个强制更新 PYTHONPATH 的脚本。

新命令：

python run_unittests.py

新脚本：

import pytest, os, sys

project_dir = os.path.dirname(os.path.abspath(__file__))
base_test_dir = os.path.join(project_dir, 'SourceCode', 'application', 'deploy', 'app', 'hao', 'lambda')

test_dirs = [
    os.path.join(base_test_dir, 'tests'),
    os.path.join(base_test_dir, 'handlers'),
    os.path.join(base_test_dir, 'utils'),
    base_test_dir
]

for i in test_dirs:
    if i not in sys.path:
        sys.path.append(i)

test_args = [a for a in sys.argv if a != 'run_unittests.py']

pytest.main([base_test_dir]+test_args)
