Question

I need to mock the following:

Class User
  def facebook
    #returns an instance of a facebook gem
  end
end

So in my User tests, to access

You could try something like this :-

user = Factory(:user)
user.stubs(:facebook => stub(:me => stub(:info => {:name => "John Doe"})))

If you really want to check that all these methods are called (which I suspect you don't), you could do the following :-

user = Factory(:user)
user.expects(:facebook => mock(:me => mock(:info => {:name => "John Doe"})))

It's a bit more verbose, but it's usually worthwhile giving each mock object a name :-

user = Factory(:user)
user.stubs(:facebook => stub('facebook', :me => stub('me', :info => {:name => "John Doe"})))

I hope that helps.
