Gherkin

# File: src/test/resources/features/login.feature

Feature: User Authentication
  Scenario: Valid login
    Given the user is on the login page
    When the user enters valid credentials
    Then the dashboard should be displayed

The first line comment after # is optional and ignored by Cucumber. The actual feature content starts with the Feature: keyword.
