使用pytest-django的自定义测试套件运行器

Question

我想切换我的Django(版本1.6x)应用程序pytest-django用于测试.因此我通过pip安装了最新的pytest-django并获得了以下版本:

pytest==2.6.4
pytest-django==2.7.0

使用常规django测试,我使用扩展DjangoTestSuiteRunner的自定义测试套件运行器,我在settings.py中配置:

settings.py:

TEST_RUNNER = "dcmanager.tests.runner.ManagedModelTestRunner"

runner.py:

import unittest

from django.conf import settings
from django.db.models import get_app, get_apps
from django.test.simple import DjangoTestSuiteRunner, build_test, build_suite, runner


class ManagedModelTestRunner(DjangoTestSuiteRunner):
    """
    Test runner that automatically makes all unmanaged models in
    project managed for the duration of the test run and patches VStorage model,
    so that one doesn't need to execute the SQL manually to create them.
    """
    IGNORE_TESTS = ['django', 'rest_framework', 'rest_framework_swagger']

    def build_suite(self, test_labels, extra_tests=None, **kwargs):
        suite = unittest.TestSuite()

        if test_labels:
            for label in test_labels:
                if '.' in label:
                    suite.addTest(build_test(label))
                else:
                    app = get_app(label)
                    suite.addTest(build_suite(app))
        else:
            ignore_list = []
            for app in get_apps():
                app_name_parts = app.__name__.split('.')
                for index, _ in enumerate(app_name_parts):
                    app_part_name = '.'.join(app_name_parts[0:index])
                    if app_part_name and app_part_name in self.IGNORE_TESTS:
                        ignore_list.append(app.__name__)
                        break
                if app.__name__ not in ignore_list:
                    suite.addTest(build_suite(app))

        if extra_tests:
            for test in extra_tests:
                suite.addTest(test)

        return runner.reorder_suite(suite, (unittest.TestCase,))

    def setup_test_environment(self, *args, **kwargs):
        if settings.STAGE == 'TEST':
            from django.db.models.loading import get_models
            self.unmanaged_models = [m for m in get_models()
                                     if not m._meta.managed]
            for m in self.unmanaged_models:
                m._meta.managed = True

        super(ManagedModelTestRunner, self).setup_test_environment(*args,
                                                                   **kwargs)

    def teardown_test_environment(self, *args, **kwargs):
        super(ManagedModelTestRunner, self).teardown_test_environment(*args,
                                                                      **kwargs)
        # reset unmanaged models
        for m in self.unmanaged_models:
            m._meta.managed = False

如何告诉pytest-django使用我的自定义测试套件运行器？

Answer 1

py.test 根本不使用单元测试运行器

恐怕你必须在 py.test 中重做自定义集合
