Before I get you all confused, let me clarify: I'm NOT asking about running a single test method with different arguments. All clear? Then let's go:

I have a test in Python (Django, but not relevant) that basically...

  • starts a http server,
  • starts Selenium, opens a web page on this server,
  • via Selenium loads and runs a suite of JavaScript tests (via Jasmine)
  • collects the results and fails if any test failed

I'd like to make the output of the each Jasmine spec visible as a separate entry in Python unit test output (with its own name)? Extracting it from Javascript via Selenium is the easy part, but I don't know how to connect it with the UnitTest machinery.

Expected code would look something like (pseudocode):

class FooPageTest(TestCase):

    def setUp(self):
        # start selenium, etc

    def run(self, result):
        self.run_tests()
        for test_name, status, failure_message in self.get_test_results():
            if status:
                result.add_successful_test(test_name)
            else:
                result.add_failed_test(test_name, failure_message)

Expected output:

$ python manage.py test FooPageTest -v2
first_external_test ... ok
second_external_test ... ok
third_external_test ... ok

A gotcha: The number and names of test cases would be only known after actually running the tests.

Is it possible to bend unittest2 to my will? How?

听起来您有多个外部测试要运行，并且您希望通过 Python 单元测试单独报告每个测试的结果。我想我会做类似的事情：

class FooPageTest(TestCase):
    @classmethod
    def setUpClass(cls):
        # start selenium, etc
        cls.run_tests()

    @classmethod
    def getATest(cls, test_name):

        def getOneResult(self):
            # read the result for "test_name" from the selenium results
            if not status:
                raise AssertionError("Test %s failed: %s" % (test_name, failure_message)
        setattr(cls, 'test%s' test_name, getOneResult)

for test_name in get_test_names():
    FooPageTest.getATest(test_name)

这种方法做了几件我认为很好的事情：

  • 它在测试将由测试发现运行而不是在模块导入时运行测试
  • 每个 selenium 测试都会生成一个 Python 测试。

要使用它，您需要定义 get_test_names()，它读取将要运行的测试的名称。您还需要一个函数来从硒结果中读取每个单独的结果，但听起来您必须已经有办法做到这一点（您的 get_test_results() 方法）。
