Rails JSON API testing POST request with PARAMS in JSON

Question

This is a problem that has been bothering me for some time. I am building an API function that should receive data in json and response in json. My controller tests run fine

Answer 1

I found my answer on a post here(RSpec request test merges hashes in array in POST JSON params), I think what I was doing wrong concerned the arguments to the request.

so this worked:

it "should return an error if there is no correct email" do
    params = {:subscription => {:email => "andre"}}

    post "/magazine_subscriptions", params.to_json, {'ACCEPT' => "application/json", 'CONTENT_TYPE' => 'application/json'}
end
