I would be glad if community help me with that. What I'm doing wrong?

[starkovv]

After 4 hours I found the solution.

config/routes.rb:

MyApp::Application.routes.draw do
  api_version(:module => 'v1', :header => 'X-Version', :value => '1', :defaults => {:format => :json}, :default => true) do
    resources :sessions
  end
end

It is required to set :module in lowercase.

I think it needs to update README in this part.

Issue closed.

[bploetz]

No, that's not the fix. If you use the header strategy, then you need to use RSpec request specs, not controller specs.

See https://github.com/bploetz/versionist/issues/17

I will add this to the README as it keeps tripping people up.

[starkovv]

I returned config/routes.rb to the previous version (now it's in UPPERCASE again):

MyApp::Application.routes.draw do
  api_version(:module => 'V1', :header => 'X-Version', :value => '1', :defaults => {:format => :json}, :default => true) do
    resources :sessions
  end
end

And I've tried the example you showed https://github.com/bploetz/versionist/issues/17:

require 'spec_helper'

describe V1::SessionsController do
  describe 'create new customer' do
    it "should work" do
        get '/sessions', {}, {'X-VERSION' => '1'} do
          assert_response 200
        end
    end
  end
end

And when I do

$ bundle exec rspec spec/controllers/v1/sessions_controller_spec.rb

I still have an error:

V1::SessionsController
  should work (FAILED - 1)

Failures:

  1) V1::SessionsController should work
     Failure/Error: get :index, nil, {'X-Version' => '1'}
     ActionController::RoutingError:
       No route matches {:controller=>"v1/sessions"}
     # ./spec/controllers/v1/sessions_controller_spec.rb:5:in `block (2 levels) in <top (required)>'

[bploetz]

you have to put the test in spec/requests

[starkovv]

I put it to spec/requests.

Now test passed. But.

If I change it to something unexpected:

require 'spec_helper'

describe V1::SessionsController do
  describe 'create new customer' do
    it "should work" do
        get '/sessions', {}, {'X-VERSION' => '1'} do
          assert_response 123456
        end
    end
  end
end

It still pass. It is strange, maybe I missed something?

[starkovv]

Update.

This version works as expected:

require 'spec_helper'

describe V1::SessionsController do
  describe 'create new customer' do
    it "should work" do
        get '/sessions', {}, {'X-VERSION' => '1'}
        response.code.should == '200'
    end
  end
end

Above is passed. And below is red:

require 'spec_helper'

describe V1::SessionsController do
  describe 'create new customer' do
    it "should work" do
        get '/sessions', {}, {'X-VERSION' => '1'}
        response.code.should == '123456'
    end
  end
end

I use webrat, probably it somehow influences.

[bploetz]

I added a section to the README about testing

[starkovv]

Thank you for your assistance with this issue. And thank you for such a gem :-)

I have just one question, is there any special tricks I should know when testing with path strategy?

[bploetz]

Since the path strategy are really just normal URLs with a prefix, everything should just work as you expect without the need for any special magic.

[starkovv]

Is it possible to rspec controllers if I use versionist gem in my project?

config/routes.rb:

MyApp::Application.routes.draw do
  api_version(:module => 'V1', :path => 'v1') do
    resources :sessions
  end
end

spec/controllers/v1/sessions_controller_spec.rb:

require 'spec_helper'

describe V1::SessionsController do
  it 'should work' do
    get '/v1/index'
  end
end

$ bundle exec rspec spec/controllers/v1/sessions_controller_spec.rb:

V1::SessionsController

[bploetz]

That route in your spec doesn't look right. It should be something like GET /v1/sessions. Run rake routes to see for sure.
