Ruby on Rails

Hey everyone,

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(Since I abstract that the data gets there already decode from JSON and only the answer needs to be interpreted ). 

I Also know that the function runs fine since I have used curl to test it with JSON arguments and it works perfectly. 

(ex: curl -i --header "Accept: application/json" --header "Content-Type: application/json" -d '{"test":{"email":"andreo@benjamin.dk"}}' <url_with_the_service>)

But obviously I would like to write request(feature) tests to test this automatically and the way I see it they should work exactly like curl, i.e., hit my service like it was an external call. That means that I would like to pass the arguments in JSON and receive an answer. I am pretty lost since all the examples I can see people treat arguments as it was already decoded. 

My question is: I am following a wrong premise in wanting to send the arguments and request as a JSON one since i will be testing that rails works, because this is its responsibility? But I would like to see how robust my code his to wrong arguments and would like to try with JSON.

something of this type:

it "should return an error if there is no correct email" do

  params = {:subscription => {:email => "andre"}}

  post "/magazine_subscriptions", { 'HTTP_ACCEPT' => "application/json", 'Content-Type' => 'application/json', 'RAW_POST_DATA' => params.to_json }

end

Do you know how this is possible? and please let me know if you think I am testing it wrong.

all the best,

Andre
