Django testrunner無法正常工作

Question

以下代碼：

class CreateSurveyFromCsvTextTests(TestCase):

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

引發以下錯誤：

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

我知道這並不能告訴您很多有關該問題的信息，這可能是環境問題，但是我是Linux / Python的新手（7天前從Windows / .Net切換），並且我真的不知道從哪里開始收集信息，更不用說診斷錯誤了。

問題是未配置數據庫。 在settings.py添加DATABASE的默認條目，並通過運行的python manage.py syncdb修復它。
