🔍 Setup and Teardown Hooks​

When you have repeated preparation or cleanup tasks, use setup and teardown hooks to DRY up your tests. setup runs before each test, and teardown runs after, ensuring a clean state. This practice keeps tests isolated and easier to maintain.

require 'minitest/autorun'

class UserTest < Minitest::Test
  def setup
    @user = User.new(name: 'Test User')
  end

  def teardown
    @user = nil
  end

  def test_user_name
    assert_equal 'Test User', @user.name
  end
end
