It'd be badass, but, basically, no. Instantiating a controller in
Rails takes a lot of work - request/response objects, routes, and the
code that does so is a big mess.
You could use factory methods, and then stub that method in your examples:
class LoginSessionsController < ApplicationController
def authenticator
TheRealAuthenticator
end
end
describe LoginSessionsController do
before(:each) do
controller.stub!(:authenticator).and_return MockAuthenticator
end
end
