How do I test my Ruby on Rails API?

You can use RSpec along with the Rails testing framework to test your API. Would you like a code example?

Yes, please provide a code example for testing a simple API endpoint.

Sure! Here's a basic example:

require 'rails_helper'

RSpec.describe 'Users API', type: :request do
  describe 'GET /users' do
    it 'returns a list of users' do
      get '/users'
      expect(response).to have_http_status(:success)
    end
  end
end

This tests that the GET request to '/users' returns a successful response.

What if I want to test for specific JSON response?

You can add expectations for the JSON response like this:

expect(JSON.parse(response.body)).to eq([{'id' => 1, 'name' => 'John Doe'}])

This checks if the response body matches the expected JSON structure.
