Question

我正在使用* django_webtest *来测试我的视图和* django_nose_selenium *来测试我网站上的ajax（我无法获得webtest.sel工作+静态文件，因为在运行单元测试时debug = False）。< / p>

我正在使用完整的测试套件 ./manage.py test project --with-selenium --with-cherrypyliveserver并且在django_webtest和硒测试之间不断变得不稳定。似乎当我有一个奇数数量的django webtest时，套件通过 - 当它是偶数数字时，我得到的SAVEPOINT只能用于事务块异常（见堆栈下面）。我发现通过添加一个简单的测试用例（assertTrue（2 == 1 + 1）。

这可能与cherrypy服务器设置有关吗？有关可能发生的事情的任何想法？您使用哪些工具组合来测试您的观点+ ajax？

Answer 1

我正在使用webtest.sel而没有问题。如果您正在进行测试，只需添加一些内容来提供静态文件

让我们说一个env var：

TEST=True ./manage.py test project

然后在你的urls.py中：

if settings.DEBUG or 'TEST' in os.environ:
    # serve static files
