This section covers recommended patterns and practices for writing effective BDD tests with Pest BDD.

Core Principles

Principle	Description
Business Language	Write scenarios that stakeholders understand
One Behavior	Test one thing per scenario
Independence	Scenarios should not depend on each other
Reusability	Write steps that work across scenarios

Quick Reference

Do's

• Use descriptive feature and scenario names
• Return objects from Given steps for injection
• Use Background for shared setup
• Keep scenarios focused and independent
• Use tags consistently across the team

Don'ts

• Don't include implementation details in scenarios
• Don't test multiple behaviors in one scenario
• Don't over-specify with unnecessary details
• Don't create dependencies between scenarios
• Don't write technical jargon in Gherkin
