How to send raw post data in a Rails functional test?

Question

I\'m looking to send raw post data (e.g. unparamaterized JSON) to one of my controllers for testing:

class LegacyOrderUpdateControllerTest < ActionControl         


        

Answer 1

As of Rails 4.1.5, this was the only thing that worked for me:

class LegacyOrderUpdateControllerTest < ActionController::TestCase
  def setup
    @request.headers["Content-Type"] = 'application/json'
  end

  test "sending json" do
    post :index, '{"foo":"bar", "bool":true}'.to_json, { account_id: 5, order_id: 10 }
  end
end

for a url at /accounts/5/orders/10/items. This gets the url params conveyed as well as the JSON body. Of course, if orders is not embedded then you can leave off the params hash.

class LegacyOrderUpdateControllerTest < ActionController::TestCase
  def setup
    @request.headers["Content-Type"] = 'application/json'
  end

  test "sending json" do
    post :index, '{"foo":"bar", "bool":true}'.to_json
  end
end
