rspec users - Apr 2008 - Stubbing class in controller

Hi,

I am trying to stub a class in my controller and I can''t get it to
work, the controller code is:

  def show
    @server = Server.find(params[:id])
    whm = Whm::Client.new @server
    @server_load = whm.loadavg
  end

and my test code:

    before(:each) do
      @server = mock_model(Server)
      Server.stub!(:find).and_return(@server)
    end

    def do_get
      get :show, :id => "1"
    end

    it "should be successful" do
      Whm::Client.stub!(:new)
      Whm::Client.stub!(:loadavg)
      do_get
      response.should be_success
    end

After running my tests I get a failure message:

''ServersController handling GET /servers/1 should be
successful'' FAILED
expected success? to return true, got false
./spec/controllers/servers_controller_spec.rb:63:

I''m not really sure how to stub this kind of class call.

Thanks
Jamie

Hi

The ''loadavg'' method is an instance method of
''whm'', so the test
should be:

@whm = mock_model(Whm::Client)
Whm::Client.stub!(:new).and_return(@whm) # make the new method to  
return a mock object
@whm.stub!(:loadavg).and_return(3) # 3 is the dummy loadavg, maybe you  
can change it in something more meaningfull

For now, there is no real reason to put this into the test itself. I  
think I would put this code in the before part.

Regards
Ivo

Thanks Ivo,

I was getting a bit confused with the stubs, thanks for the explanation.
