I am working on setting up integration testing of our Phoenix-application using Hound. I encountered a very strange error, which is that when using PhantomJS as Hound browser driver, Cowboy will reject all incoming connection with an ‘error 400’.
Searching the internet I found out that other people had a similar problem with Cowboy as well: PhantomJS does not by default seem to add a Host:-header to the requests it does, which is against the HTTP spec and rejected by Cowboy (as well as happily accepted by most other webservers).
Switching to Selenium+Firefox instead of PhantomJS and everything works fine.
So just a heads-up that this issue exists. I’m not sure how this could/should be resolved; what would be the best approach?
- Ask the developers of PhantomJS to alter its default settings so it follows the spec.
- Update Hound so it requests PhantomJS to set a
Host:-header when connecting. - Update Hound so it has the possibility to add custom HTTP headers from your own code.
- Ask the people behind Cowboy to create a way to accept requests with missing
Host:-headers.

I think it might be easier to switch to chrome. I’m not sure if there’s anyone left to develop phantomjs further at this point: Redirecting to Google Groups.
I mostly use GitHub - puppeteer/puppeteer: JavaScript API for Chrome and Firefox · GitHub for “end-to-end” tests.

At first I switched to Selenium + Firefox, but lo and behold,
Houndcrashes whenever you try to run afind_elementbecause it cannot understand the current format that is returned by the webdriven Firefox.The Selenium+Chrome driver still works fine, though.
@idi527 Do you use puppeteer instead of Hound, or somehow from within Hound? I’d like to keep all my tests in Elixir-land, because the existing tests are, and because most of the stuff is server-side related anyway.

Yes, I got frustrated with
HoundandWallabyat the time, and just wrote these tests in js, which was surprisingly easy.
