jcorpac BDD & Gherkin
Behavior-Driven Development (BDD) encourages collaboration between developers, QA, and non-technical stakeholders.
Gherkin Syntax
Tests are written in plain English using the Given, When, Then format:
- Scenario: A specific behavior being tested.
- Given: The initial context or state.
- When: An event or action occurs.
- Then: The expected outcome or consequence.
Example Feature File
Feature: User Login
Scenario: Successful login with valid credentials
Given the user is on the login page
When they enter "valid_user" and "valid_password"
And they click the login button
Then they should be redirected to the dashboard
And they should see a "Welcome back" message
Best Practices
- Focus on Outcomes: Spend more time on the Then than the When.
- Avoid Technical Details: Feature files should not mention buttons, IDs, or implementation details.
- Collaborate Early: Write feature files with the product owner before coding starts.
