Question

I tried testing routes and just copied the example from the rspec-rails documentation.

describe "routing to profiles" do
  it "routes /profile/:username to profile#show for username" do
    expect(:get => "/profiles/jsmith").to route_to(
      :controller => "profiles",
      :action => "show",
      :username => "jsmith"
    )
  end
end

I got the following error when running RSpec:

Failures:

  1) routing to profiles routes /profile/:username to profile#show for username
     Failure/Error: expect(:get => "/profiles/jsmith").to route_to(
     ArgumentError:
       wrong number of arguments (1 for 0)
     # ./spec/routing/test_spec.rb:11:in `block (2 levels) in <top (required)>'

Finished in 0.001 seconds
1 example, 1 failure

What’s going wrong here?

Thanks for any help.

Answer 1

expect takes a block. This means use curly brackets:

expect{ :get => "/profiles/jsmith" }.to route_to(

Reference: RSpec Expectations 2.0

I don’t think you need expect anyway. Code from Testing an RSpec controller action that can't be accessed directly

describe "routing" do
  it "routes /auth/:provider/callback" do
    { :post => "/auth/twitter/callback" }.should route_to(
      :controller => "authentications",
      :action => "create",
      :provider => "twitter")
  end
end
