如何从 python manage.py test 调用 pytest-django？

Question

我已经制作了名为 pytest_wrp 的自定义管理命令

所以当我打电话时

python manage.py test

这段代码称为：

class Command(test.Command):

    def handle(self, *args, **options):
        super(Command, self).handle(*args, **options) # this calls the python manage.py test
        self.stdout.write("My code starts from here.")
        management.call_command(pytest_wrp.Command(), '--pact-files="{argument}"'.format(argument=path_to_file), '--pact-provider-name="MyService"', verbosity=0)

基本上pytest_wrp有这样的代码：

class Command(BaseCommand):
    help = "Runs tests with Pytest"

    def add_arguments(self, parser):
        parser.add_argument("args", nargs=argparse.REMAINDER)

    def handle(self, *args, **options):
        pytest.main(list(args)) # This doesn't accept the pact args, even if you specify a "--" separator

但这pytest并不pytest-django 意味着我传递的额外参数不会被识别，并且 pytest 无法启动测试套件。

我想传递一些测试用例的额外参数。如果有某种方法可以直接调用 pytest-django 并在代码中传递额外的参数，那将是最佳的。

我在这里找到了我的解决方案： 切换到 django-pytest 后我仍然可以使用`manage.py test`吗？ 要获得完整且全面的文档，您需要查看此。简而言之，您需要重写config/test.py或 ，config.py具体取决于您的应用程序的设置方式

TEST_RUNNER = "your_project.your_app.runner"

你的runner.py看起来像这样

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')

        # NOTE: You don't need to quote the argument value here, they do some weird string pattern matching internally
        argv.append('--pact-files={argument}'.format(argument=path_to_file)) 
        argv.append('--pact-provider-name=MyService')
        argv.extend(test_labels)
        return pytest.main(argv)

请确保您有pytest-django包裹

pip install pytest-django
