Rails 3 RSpec Request Spec – Testing Subdomains

without comments

How do you test sub-domains in RSpec Request specs (integration tests) ???

# Pass it into the GET request!
get '/programs/100', nil, {'HTTP_HOST' => ''}

The 3rd parameter to the get method is a hash of HTTP headers.
See the Rails API documentation for details.

Depending on the type of test you are working with (support / controller / request / integration etc.) you pass in the sub domain differently.

Here’s some good reference posts on Stack Overflow for setting subdomains in controller specs:
1. Rails RSpec Set Subdomain

# Set the in a before block
before(:each) do = "#{mock_subdomain}"

2. Subdomains in RSpec Controller Tests

 # I haven't tried this, and not sure you would need to mock out the current_subdomain method.
  @subdomain = ''
  controller.expects(:current_subdomain).returns(@subdomain) = "#{@subdomain}"

RSpec – Running One Single Test at a Time

without comments

In the old days I would pass a regular expression to run a particular unit test or group of similarly named unit tests by name.

Here’s the easy way to run one test in RSpec… by line number!
Look at the line-number of any RSpec block (it, describe, etc), and simply run the rspec command, passing in the [filename]:[line number]:

$ rspec models/user_spec.rb:27

Happy testing!
