Shoulda Test in Rails 3: should respond_with :success

Question

I have some troubles with testing in Rails 3. I'm currently upgrading a Rails2 app to Rails3. I'm using shoulda for testing. In my functional tests, I'm testing with shoulda, that a GET should respond with success

context "GET to :blame" do
  should "mark a song as blamed" do
    get :blame, :id => @song.id
    assert_equal Blame.count, 1
    get :blame, :id => @song.id
    assert_equal Blame.count, 2
  end
  should respond_with :success
end

In the next to last line I'm getting the following error while executing the functional tests with rake test:functionals:

  1) Error:
test: a visitor GET to :blame should respond with 200. (SongsControllerTest):
NoMethodError: undefined method `response_code' for nil:NilClass

I'm using Ruby 1.9.2, Rails 3.0.3 and Shoulda 2.11.3. Hope, someone can help me.

thx, tux

The two should blocks are run separately and no request would be made for respond_with hence the error. You would need to make the request in a setup block such as:

context "GET to :blame" do
  setup do
    get :blame, :id => @song.id
  end
  should "mark a song as blamed" do
    assert_equal Blame.count, 1
  end
  should respond_with :success
end
