从 Python 中的子目录运行所有测试 [英] Run all tests from subdirectories in Python

问题描述

我在试图让我的所有单元测试在 Python 中运行时不知所措.我已经搜索了大约 30 个不同的帖子和单元测试文档，但仍然无法弄清楚.

I am at my wits end with trying to get all my unittest to run in Python. I have searched about 30 different posts and the unit test documentation but still cannot figure it out.

首先我有两个测试类，我可以单独运行每个类并且所有测试都通过:

First I have two test classes that I can run each individually and all the tests pass:

文件:unittest.subfolder1.TestObject1.py

File: unittest.subfolder1.TestObject1.py

class TestObject1(unittest.TestCase):
  def test_case1(self):
    ...some code...
    ...some assertions...

if __name__ == '__main__':
  unittest.main()

文件:unittest.subfolder2.TestObject2.py

File: unittest.subfolder2.TestObject2.py

class TestObject2(unittest.TestCase):
  def test_case1(self):
    ...some code...
    ...some assertions...

if __name__ == '__main__':
  unittest.main()

从unittest"上方的顶级目录开始，我试图让我们 unittest.discover 找到并运行我的所有测试:

Starting in the top level directory above 'unittest' I am trying to us unittest.discover to find and run all my tests:

import unittest

loader = unittest.TestLoader()
suite = loader.discover('unittest')
unittest.TextTestRunner().run(suite)

当我这样做时，我收到错误 `ModuleNotFoundError: No module named 'subfolder1.TestObject1'

When I do this I get the error `ModuleNotFoundError: No module named 'subfolder1.TestObject1'

我做错了什么?

推荐答案

所以我不得不做我自己的解决方法，但至少我可以让它们以上述文件结构运行.它要求我每次给它一个新的文件路径时重新实例化TestLoader和TestSuite，所以首先我需要在unittest目录中收集所有相关的文件路径.

So I had to do my own workaround but at least I can get them all to run with the above file structure. It requires that I reinstantiate the TestLoader and the TestSuite each time I give it a new file path, so first I need to collect all relevant file paths in the unittest directory.

import os
import unittest
import traceback


class UnitTestLauncher(object):

  def runTests(self):
    #logging.INFO("Running unit tests...")


    lsPaths = []

    #Find all relevant subdirectories that contain unit tests
    #Exclude 'unittest' directory, but include subdirectories, with code `path != 'unittest'`
    for path,subdirs,files in os.walk('unittest'):
      if "pycache" not in path and path != 'unittest':
        lsPaths.append(path)

    #loop through subdirectories and run individually
    for path in lsPaths:
      loader = unittest.TestLoader()
      suite = unittest.TestSuite()
      suite = loader.discover(path)
      unittest.TextTestRunner().run(suite)

这个解决方案并不完美，每个不同的目录都作为一行输出出现，因此您必须手动查看每一行以查找失败的测试.

This solution is not perfect and each different directory comes out as a line of output so you have to look through each line manually for failed tests.
