我有一个Django项目,其中在manage.py中设置了某些环境变量,该变量随后用作settings.py中定义的值。因此,为了运行pytest-django,我想先运行manage.py

我试图按照https://pytest-django.readthedocs.io/en/latest/faq.html#how-can-i-use-manage-py-test-with-pytest-django中的说明进行操作,但是遇到了意外错误。我有以下目录结构:

.
├── lucy
│   ├── settings
    │   ├── base.py
    │   ├── development.py
    │   ├── production.py
│   └── staging.py
│   ├── staticfiles
│   ├── urls.py
│   └── wsgi.py
├── lucy_web
│   ├── __init__.py
│   ├── actions.py
│   ├── admin
│   ├── apps.py
│   ├── fixtures
│   ├── forms
│   ├── lib
│   ├── management
│   ├── migrations
│   ├── models
│   ├── runner.py
│   ├── serializers.py
│   ├── static
│   ├── templates
│   ├── templatetags
│   ├── tests
│   ├── urls.py
│   └── views
├── manage.py
├── pytest.ini


runner.py的内容完全来自于FAQ:

class PytestTestRunner(object):
    """Runs pytest to discover and run tests."""

    def __init__(self, verbosity=1, failfast=False, keepdb=False, **kwargs):
        self.verbosity = verbosity
        self.failfast = failfast
        self.keepdb = keepdb

    def run_tests(self, test_labels):
        """Run pytest and return the exitcode.

        It translates some of Django's test command option to pytest's.
        """
        import pytest

        argv = []
        if self.verbosity == 0:
            argv.append('--quiet')
        if self.verbosity == 2:
            argv.append('--verbose')
        if self.verbosity == 3:
            argv.append('-vv')
        if self.failfast:
            argv.append('--exitfirst')
        if self.keepdb:
            argv.append('--reuse-db')

        argv.extend(test_labels)
        return pytest.main(argv)


最后,在lucy/settings/base.py中添加以下行:

TEST_RUNNER = 'lucy_web.runner.PytestTestRunner'


最后,pytest.ini文件与docs中的示例相同:

# -- FILE: pytest.ini (or tox.ini)
[pytest]
DJANGO_SETTINGS_MODULE = lucy.settings.production
# -- recommended but optional:
python_files = tests.py test_*.py *_tests.py


问题是pytest似乎无法找到测试。如果我运行命令

python manage.py test lucy_web.tests


我懂了

(venv) Kurts-MacBook-Pro:lucy-web kurtpeek$ python manage.py test lucy_web.tests
============================================ test session starts ============================================
platform darwin -- Python 3.6.4, pytest-3.3.2, py-1.5.2, pluggy-0.6.0
rootdir: /Users/kurtpeek/Documents/Dev/lucy/lucy-web, inifile: pytest.ini

======================================= no tests ran in 0.00 seconds ========================================
ERROR: file not found: lucy_web.tests


但是,如果我注释掉TEST_RUNNER中的base.py行并运行相同的命令,则测试将成功运行:

(venv) Kurts-MacBook-Pro:lucy-web kurtpeek$ python manage.py test lucy_web.tests
Creating test database for alias 'default'...
System check identified no issues (0 silenced).
....E.F................
----------------------------------------------------------------------
Ran 23 tests in 15.974s

FAILED (failures=1, errors=1)
Destroying test database for alias 'default'...


我在这里做错了什么?我是否需要将runner.py放在其他位置?

最佳答案

也许是因为__init__.py

使用pytest时,我遇到了类似的情况。我在测试目录中删除了__init__.py,它测试得很好。

情况略有不同,但我希望这会有所帮助。

关于python - 使用带有pytest-django的manage.py的“找不到文件”,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/48179315/
