How to check for a JSON response using RSpec?

Question

I have the following code in my controller:

format.json { render :json => { 
        :flashcard  => @flashcard,
        :lesson     => @lesson,
             


        

Answer 1

For Your JSON response you should parse that response for expected results For Instance: parsed_response = JSON.parse(response.body)

You can check other variables which is included in response like

expect(parsed_response["success"]).to eq(true)
expect(parsed_response["flashcard"]).to eq("flashcard expected value")
expect(parsed_response["lesson"]).to eq("lesson expected value")
expect(subject["status_code"]).to eq(201)

I prefer also check keys of JSON response, For Example:

expect(body_as_json.keys).to match_array(["success", "lesson","status_code", "flashcard"])

Here, We can use should matchers For expected results in Rspec
