django-discover runner和XML报告

Question

我有一个可以工作的Django应用程序，它已经成功地使用unittest-xml-reporting从我的单元测试中生成XML报告。

然而，这个项目正在迅速发展，我想将我的测试分解到每个应用程序中的单独文件中。因此，我安装了django-discover-runner，它可以找到我所有的测试文件并成功地运行它们。

但是，django-discover-runner不会生成我需要的报告(对于竹子)。

我发现了这个：

并尝试实现该建议(在我的每个test.py文件中)，但是没有生成任何XML。

如何同时使用django-discover-runner和unittest-xml-reporting来发现我的测试并生成XML报告？

Answer 1

所以事实证明，解决这个问题比我预期的要容易得多。对于可能想要这样做的任何其他n00bs：

简单地说，我只是将django-discover-runner和unittest-xml-reporting提供的两个测试运行器拼凑成一个自定义的测试运行器：

from django.conf import settings
from django.test.utils import setup_test_environment, teardown_test_environment
import xmlrunner
from django.core.exceptions import ImproperlyConfigured
from django.test import TestCase
from django.test.simple import DjangoTestSuiteRunner, reorder_suite
from django.utils.importlib import import_module

try:
    from django.utils.unittest import defaultTestLoader
except ImportError:
    try:
        from unittest2 import defaultTestLoader  # noqa
    except ImportError:
        raise ImproperlyConfigured("Couldn't import unittest2 default "
                               "test loader. Please use Django >= 1.3 "
                               "or go install the unittest2 library.")

### CUSTOM RUNNER NAME
class myTestRunner(DjangoTestSuiteRunner):
    ### THIS SECTION FROM UNITTESTS-XML-REPORTING
    def build_suite(self, test_labels, extra_tests=None, **kwargs):
        suite = None
        root = getattr(settings, 'TEST_DISCOVER_ROOT', '.')
        top_level = getattr(settings, 'TEST_DISCOVER_TOP_LEVEL', None)
        pattern = getattr(settings, 'TEST_DISCOVER_PATTERN', 'test*.py')

        if test_labels:
            suite = defaultTestLoader.loadTestsFromNames(test_labels)
            # if single named module has no tests, do discovery within it
            if not suite.countTestCases() and len(test_labels) == 1:
                suite = None
                root = import_module(test_labels[0]).__path__[0]

        if suite is None:
            suite = defaultTestLoader.discover(root,
                pattern=pattern, top_level_dir=top_level)

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

        return reorder_suite(suite, (TestCase,))

    ###THIS SECTION FROM DJANGO-DISCOVER-RUNNER
    def run_tests(self, test_labels, extra_tests=None, **kwargs):
        """
        Run the unit tests for all the test labels in the provided list.
        Labels must be of the form:
         - app.TestClass.test_method
        Run a single specific test method
         - app.TestClass
        Run all the test methods in a given class
         - app
        Search for doctests and unittests in the named application.

        When looking for tests, the test runner will look in the models and
        tests modules for the application.

        A list of 'extra' tests may also be provided; these tests
        will be added to the test suite.

        Returns the number of tests that failed.
        """
        setup_test_environment()

        settings.DEBUG = False

        verbosity = getattr(settings, 'TEST_OUTPUT_VERBOSE', 1)
        if isinstance(verbosity, bool):
            verbosity = (1, 2)[verbosity]
        descriptions = getattr(settings, 'TEST_OUTPUT_DESCRIPTIONS', False)
        output = getattr(settings, 'TEST_OUTPUT_DIR', '.')

        suite = self.build_suite(test_labels, extra_tests)

        old_config = self.setup_databases()

        result = xmlrunner.XMLTestRunner(
            verbosity=verbosity, descriptions=descriptions,
            output=output).run(suite)

        self.teardown_databases(old_config)
        teardown_test_environment()

        return len(result.failures) + len(result.errors)

这应该保存在你的项目中合适的地方。在测试设置文件(test_settings.py -根据django-discover-runner说明)中，设置测试运行器：

TEST_RUNNER = '<your-django-project>.customTestRunner.myTestRunner'

然后，您将使用(同样，根据django-discover-runner说明)：

django-admin.py test --settings=myapp.test_settings

这个解决方案允许我使用django-discover-runner的特性来发现我的项目中的所有测试文件--由django-discover-runner的TEST_DISCOVER_PATTERN选项指定--并且仍然按照竹子的要求输出XML报告。

django-discover-runner

unittest-xml-reports

Answer 2

由于提出了这个问题，unittest-xml-reporting项目具有新的Django DiscoverRunner类的added support。您可以在Django设置文件中设置测试运行器：

TEST_RUNNER = 'xmlrunner.extra.djangotestrunner.XMLTestRunner'

它将运行与DiscoverRunner相同的测试。
