So I have some features I'm wanting to test.
For a portion of the features I'm wanting to have requests placed to a different host.
When I'm testing my code locally (outside of Capybara) I'm able to use localhost:3000 for a portion of the requests, and 0.0.0.0:3000 for another portion of the requests.
Any thoughts on the best approach to replicating this approach with Capybara?
If I set the default host to localhost:3000 and spin up a server myself it works. But haven't yet been able to get it to work otherwise.
FWIW I'm using poltergeist as the js driver.
The two Capybara settings that control the app under test server it starts are Capybara.server_host (defaults to 127.0.0.1) and Capybara.server_port (default to a random free port). One way to get what you want is to fix the port and then pick a domain that resolves everything to 127.0.0.1 for all hostnames (.test on your machine possibly - or add a new name to your hosts file that resolves to 127.0.0.1)
Capybara.server_port = 9999
visit('/') # will go to http://127.0.0.1:9999/
visit('http://127.0.0.1:9999')
visit('http://my_app.test:9999')
The other option is to set Capybara.always_include_port = true which will override the port for any visit call that doesn't specifically include a port with the port Capybara has run its server on (which can therefore remain a random port Capybara picks)
Capybara.always_include_port = true
visit('/') # http://127.0.0.1:<server_port>/
visit('http://my_app.test') # http://my_app.test:<server_port>
visit('http://google.com') # http://google.com:<server_port>
visit('http://google.com:80/') # http://google.com
