Testing Vote Storage

To test the basics of the vote-casting functionality, add the following test to test/functional/votes_controller_test.rb. It simply confirms that new votes are stored correctly:

28-votes_controller_test.rb (excerpt)

class VotesControllerTest < ActionController::TestCase

def test_should_accept_vote

assert stories(:two).votes.empty?

post :create, :story_id => stories(:two)

assert ! assigns(:story).votes.empty?

end

end

The test uses a before-and-after check to confirm that this action, which is supposed to modify data, is indeed doing its job. Let’s look at each line in turn.

The first line confirms that the story initially has no votes:

assert stories(:two).votes.empty?
