django-discover-runner和XML报告？

Question

我有一个有效的Django应用程序,它已成功unittest-xml-reporting用于从我的单元测试中生成XML报告.

但是,该项目正在快速增长,我想将我的测试分解为每个应用程序中的单独文件.因此我安装django-discover-runner了找到我的所有测试文件并成功运行它们.

但是,django-discover-runner不会产生我需要的XML报告(对于Bamboo).

我发现了这个:

并尝试实现该建议(在我的每个test.py文件中),但没有生成XML.

如何使用它们django-discover-runner并unittest-xml-reporting发现我的测试并生成XML报告？

Answer 1

自从提出这个问题以来，unittest-xml-reporting项目增加了对新Django DiscoverRunner类的支持。您可以在Django设置文件中设置测试运行器：

TEST_RUNNER = 'xmlrunner.extra.djangotestrunner.XMLTestRunner'

它将运行与测试相同的测试DiscoverRunner。

所以事实证明，这个问题的解决方案比我预期的要容易得多。对于可能希望这样做的任何其他 n00b：

简短的回答是，我根本鹅卵石所提供的两个测试选手一起django-discover-runner，并unittest-xml-reporting到自定义测试运行：

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

         - app.TestClass

         - 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。在您的测试设置文件（test_settings.py- 按照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（再次，按照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的功能来发现我项目中的所有测试文件 - 由django-discover-runner'TEST_DISCOVER_PATTERN选项指定- 并且仍然按照 Bamboo 的要求输出 XML 报告。非常感谢原始代码的作者：
