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.
