Rails: invalid host name for rsspec url helpers

Question

Url helpers (e.g. root_url) return a different hostname in application controllers against rspec examples. I was able to successfully set the domain for URL Helpers in my rails application as follows:

class ApplicationController < ActionController::Base def default_url_options {host: "foo.com", only_path: false} end end 

For example, root_url displays "http://foo.com/" in the application, but "http://example.com" in my query specifications. What is the recommended way to apply these URL parameters globally in rails 3.2 so that they affect my specifications? URL parameters do not have to be dynamic.

Answer 1

In the specifications of the features, host! outdated. Add them to your rspec_helper.rb:

 # Configure Capybara expected host Capybara.app_host = 'http://lvh.me:3000' # Configure actual routes host during test before(:each) do if respond_to?(:default_url_options) default_url_options[:host] = 'http://lvh.me:3000' end end 

Answer 2

Just to add an answer to Dan, it will look something like this in spec_helper.rb

 RSpec.configure do |config| # other config options config.before(:each) do host! "localhost:3000" end end 

Answer 3

You can set the host in front of the block in your test in rspec:

  before :each do host! 'hostgoeshere.com' end 

If you want to install it globally, you can put something in your spec_helper.rb file.

I tried a lot of options @request.host , host! and post path, args, {'SERVER_NAME' => my_secret_domain} without success, both in controller tests and in function tests. Very aggravating, as many others have reported success with these approaches.

The solution for me was:

 request.headers["SERVER_NAME"] = my_secret_domain post path, args 

I am running ruby ​​2.1.5p273, rspec 3.1.7 and Rails 4.2.0
