Gherkin is a simple, easy-to-read language used in Behavior-Driven Development (BDD) to describe software behavior without programming. It's widely used for writing acceptance tests in tools like Cucumber.

Basic Structure

A Gherkin file typically includes:

  • Feature (the overall purpose)
  • Scenario (a specific example of behavior)
  • Steps (actions, outcomes, and expectations)
Feature: User Login
  Scenario: Successful login with valid credentials
    Given I am on the login page
    When I enter "username" and "password"
    Then I should be redirected to the dashboard

Key Keywords

Keyword Description
Feature Defines the scope of the test
Scenario Represents a specific test case
Given Sets up the initial context
When Describes the action taken
Then States the expected outcome

Best Practices

  • Use clear, concise language ✅
  • Keep steps atomic (single action per line) 📌
  • Include both positive and negative scenarios ⚠️
