Question

I m using Shoulda, Mocha, and Test::Unit for testing. I have the following controller and test:

class FoosController < ApplicationController
  caches_action :show
  def show
    @foo = requested_foo
  end
  private
  def requested_foo
    Foo.find(params[:id])
  end
end


class FoosCachingTest < ActionController::IntegrationTest
  def setup
    @foo = Foo.first
    @session = open_session
  end

  context  FoosController#show  do
    setup do
      @session.get( /foos/1 )
    end

    before_should  not fetch the Foo from the database  do
      FoosController.any_instance.expects(:requested_foo).never
    end

    before_should  fetch the Foo from the database  do
      FoosController.any_instance.expects(:requested_foo).once.returns(@foo)
    end
  end
end

How is it that both of those tests could pass? I am not explicitly expiring my mocks at any point. Are Mohca and Shoulda known to interact poorly in this regard?

Answer 1

Aha! The problem is that the expectations do indeed fail but the errors they throw are swallowed up by the controller s error handling. Testing that the action renders properly makes the proper test fail.
