Python存储库组织WRT测试和PyDev

Question

I'm trying to set up a Python repository for some code. I've read the Structuring Your Project tutorial and set everything up as suggested. Concretely, I have the following directory structure:

repo_root/
   some_module.py
   tests/
       context.py
       test_some_module.py

The context.py file contains exactly what the tutorial suggests:

import os
import sys
sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), '..')))

import some_module

The test_some_module.py file imports some_module like so:

from context import some_module

instead of

from .context import some_module

as the site suggests.

I'm using PyDev and running the unit tests by right-clicking on the test file and selecting Run As/unittest . This causes the test to run in the tests directory, where context is visible and the import is successful. PyDev shows Unresolved import . I'm guessing this is because it runs the parser from the project root. If I add tests to the PYTHONPATH it still doesn't work. Only if I add an __init__.py file in tests does PyDev stop showing errors, because it's treating tests as a library.

What is the correct way to set up my repository? Are tests supposed to only be called in the tests directory or should they also be start-able from the repository root?

如果您的包中没有__init__文件（即使是用于测试），PyDev的效果也不佳，因此，我的建议是在其中添加__init__ 。
