Testing Responses: Challenge 1 of 1

Add an assertion to make sure the response was successful

At first I thought it was:

assert_response :successful

(seems logical, right?)

after much searching on the forum I came across this post:


that had this code:

    should "get new and return success" do
        get :new
        assert_response :success

Hmmmmmm - so I thought maybe:

        get :new

        assert_response :success

but nooooooooooooooo!

Alright, then...maybe just drop the

get :new (don't repeat it twice..because it already has one 'get:new' to start with..

Yes! It passed (whew)

Morale of the story: don't over think this question, but do search the forum for code snippets --there is a lot of good content there :)

can you post a link to the challenge? i cant give you a definite answer without seeing it myself but the Rails Testing Guide lists some of the assertions that come with mini test, one of them being


Asserts that the response comes with a specific status code. You can specify :success to indicate 200-299, :redirect to indicate 300-399, :missing to indicate 404, or :error to match the 500-599 range. You can also pass an explicit status number or its symbolic equivalent.

so to assert that the response was successful you would use:

assert_response :success
