Set Rspec default GET request format to JSON

Question

I am doing functional tests for my controllers with Rspec. I have set my default response format in my router to JSON, so every request without a suffix will return JSON.

Answer 1

Running Rails 5 and Rspec 3.5 I had to set the headers to accomplish this.

post '/users', {'body' => 'params'}, {'ACCEPT' => 'application/json'}

Thi matches what the example in the docs looks like:

require "rails_helper"

RSpec.describe "Widget management", :type => :request do
  it "creates a Widget" do
    headers = {
      "ACCEPT" => "application/json",     # This is what Rails 4 accepts
      "HTTP_ACCEPT" => "application/json" # This is what Rails 3 accepts
    }
    post "/widgets", { :widget => {:name => "My Widget"} }, headers

    expect(response.content_type).to eq("application/json")
    expect(response).to have_http_status(:created)
  end
end
