我正在使用* django_webtest *來測試我的視圖和* django_nose_selenium *來測試我的網站上的ajax（我無法獲取webtest.sel工作+靜態文件沒有得到服務，因爲調試=運行單元測試時出現錯誤）。Django WebTest和Django鼻子Selenium SAVEPOINT錯誤
我正在使用 ./manage.py test project --with-selenium --with-cherrypyliveserver運行完整的測試套件，並且在django_webtest和硒測試之間不斷髮生變化。 這似乎是當我有一個奇數 django webtest的數量，該套件通過 - 當它是一個甚至號碼，我得到SAVEPOINT只能用於事務塊異常（見下面的堆棧）。我發現通過添加一個簡單的測試用例（assertTrue（2 == 1 + 1）。
這可能與cherrypy服務器設置有關嗎？有關可能發生什麼的任何想法？ 您有哪些工具組合用它來測試你的意見+ AJAX？
