如何使用webtest-django测试login-remember-me功能？换句话说，您如何使用webtest来测试涉及浏览器退出cookie过期的内容？我有以下草案，但它不起作用。似乎必须设置和拆除服务器（如我的测试类下面的代码片段），但我不了解如何集成它。以这种方式使用StopableWSGIServer似乎没有太多信息。
最后，我甚至不确定这个功能在生产中是否能够正常工作，因为我的理解是主要浏览器忽略expire-cookie-on-browser-exit请求。那是对的吗？很高兴看到一些关于它的参考文献。

仅供参考：这是一个针对登录页面的全功能测试，忽略了remember-me功能。这就是我基于以上内容的原因：

答案 0 :(得分：0)
Cookie保存在会话中。所以
self.app.set_user(user=None)
self.app.reset()
应取消设置用户并清除客户端会话（包括cookie）。这样，您可以模拟浏览器重启。
http.StopableWSGIServer.shutdown()停止了，我认为是服务器端（wsgi=server-app connection）。
