Capybara-webkit raises Capybara::Driver::Webkit::WebkitInvalidResponseError

Question

I got following message from webkit driver in my rspec:

Capybara::Driver::Webkit::WebkitInvalidResponseError:
Unable to load URL: http://127.0.0.1:44923/posts

Few days ago it worked. The problem is with save_page method. What could be wrong?

Answer 1

I've had similar error messages when my page was raising an error. You should check manually that this is not the case by starting a server in testing mode (rails s -e test) and accessing the page yourself.

Answer 2

Try removing gem thin from your bundle completely.

Even if it is in :development or :production group only!

Answer 3

In your test.rb:

set config.action_dispatch.show_exceptions = true

and you will see the exception that caused the WebkitInvalidResponseError

Answer 4

Check if you don't have any other error in your application that could prevent Capybara from loading the page. Last time I got it, I realized that there was a 500 error page and that was why Capybara raised Capybara::Driver::Webkit::WebkitInvalidResponseError.
