以下代码：

class CreateSurveyFromCsvTextTests(TestCase):

    def test_parses_survey_passed_in_as_csv_and_returns_xml_representation(self):
        self.assertTrue(True)

引发以下错误：

ERROR: test_parses_survey_passed_in_as_csv_and_returns_xml_representation (dkobo.formbuilder.tests.CreateSurveyFromCsvTextTests)
