如何模拟与Java / Selenium的连接断开？

Question

We're using Selenium 2 with Java in our test automation process. Our web application periodically polls for new information - if it can't connect to the server (ie. server down, cable unplugged, ...), a popup should appear.

Is there any (easy) way to simulate a lost connection in Java or directly in Selenium?

Answer 1

Yes, you can. I'm using Vaurien , the chaos TCP proxy to simulate network problems.

According to the documentation, an example to add 20% delay of all HTTP requests:

vaurien --protocol http --proxy localhost:8000 --backend google.com:80 --behavior 20:delay

You can find all "behaviors" here: http://vaurien.readthedocs.org/en/1.8/behaviors.html In my opinion, hang behavior can be useful for you.
