How do I change the default “www.example.com” domain for testing in rails?

Question

I have a rails application which acts differently depending on what domain it\'s accessed at (for example www.myapp.com will invoke differently to user.myapp.com). In produc

Answer 1

I believe you can modify the HTTP_HOST or SERVER_NAME environment vars to change the request that goes to the router:

ENV['SERVER_NAME'] = "user.myapp.com"

See raw_host_with_port in actionpack/lib/action_controller/request.rb.

Answer 2

Feature specs

In Feature specs, host! has been deprecated. Add these to your spec_helper.rb:

# Configure Capybara expected host
Capybara.app_host = "http://test.domain"

# Configure actual routes host during test
before(:each) do
  default_url_options[:host] = <myhost>
end

Request specs

In Request specs, keep using host! :

host! "test.domain"

Alternatively refactor it in before(:each) blocks, or configure it globally for request specs at spec_helper.rb level:

RSpec.configure do |config|
  config.before(:each, type: :request) do
    host! "test.domain"
  end
end

Answer 3

For Rspec Request specs, use before(:each) { host! 'example.com' }

Answer 4

I think all answers are incomplete here... To enumerate all possible cases:

• Integration Specs (inheriting from ActionDispatch::IntegrationTest):

  host! "my.awesome.host"
  

  See the docs, section 5.1 Helpers Available for Integration Tests.

• Controller Specs (inheriting from ActionController::TestCase)

  @request.host = 'my.awesome.host'
  

  See the docs, section 4.4 Instance Variables Available.

• Feature Specs (through Capybara)

  Capybara.default_host = "http://my.awesome.host"
  # Or to configure domain for route helpers:
  default_url_options[:host] = "my.awesome.host"
  

  From @AminAriana's answer

• View Specs (inheriting from ActionView::TestCase)

  @request.host = 'my.awesome.host'
  

  ...or through RSpec:

  controller.request.host = "my.awesome.host"
  

  See the rspec-rails view spec docs.

Answer 5

Yet another answer:

request.host = "user.myapp.com"

I know it resembles the correct answer, but please bear with me. I don't like assignment operation in test just to set things up, I'd prefer an explicit stub. Interestingly, stubbing like this won't work:

allow(request).to receive(:host).and_return("user.myapp.com")

I personally prefer stubbing over assignment, that way I get 2 benefit, one is that it will be validated by rspec's verify double, second is that it is explicitly saying that is a stub, not part of the test excercise.

Answer 6

@request.host = 'user.myapp.com' is not right. should use host!('user.myapp.com')
