Thanks @pvev and @JulienTant. I have added the test case and implemented the suggestions. Can you please review it once more ? I would like to highlight that I have added a new test file for login_close_server_spec.js. I tried adding the test case in the already present file login_spec.js but applying different server config for different test cases in the same file did not seem to work. Please suggest if you think this could be done in a better way ?

You would need to change the values inside of your test case but make sure the before or beforeEach reset everything back to what is expected by the other test cases.

I tried but it just won't work so I thought of having a separate file for it
