# Testing Rails Applications

# Unit Test

Unit tests test parts of the application in isolation. usually a unit under test is a class or module.

let(:gift) { create :gift }

describe '#find' do
  subject { described_class.find(user, Time.zone.now.to_date) }
  it { is_expected.to eq gift }


This kind if test is as direct and specific as possible.

# Request Test

Request tests are end to end tests that imitate the behavior of a user.

it 'allows the user to set their preferences' do
  check 'Ruby'
  click_on 'Save and Continue'
  expect(user.languages).to eq ['Ruby']


This kind of test focuses on user flows and runs through all layers of the system sometimes even rendering javascript.
