What are Hooks in Cucumber?

Hooks in Cucumber are special blocks of code that execute automatically before or after scenarios. They help automation engineers perform common setup and cleanup tasks without repeating code inside individual test scenarios.

The most commonly used hooks are Before Hooks and After Hooks. Before Hooks execute before a scenario starts and are typically used for browser initialization, test data preparation, and environment setup. After Hooks execute after scenario completion and are commonly used for browser closure, log collection, screenshot capture, and cleanup activities.

Hooks improve framework maintainability by centralizing reusable actions and reducing duplication across test cases. Because of their importance in automation framework design, Hook-related questions are frequently asked during Selenium and Cucumber interviews.

Common Uses of Hooks in Automation Frameworks

• Browser Initialization Before Test Execution
• Closing Browser Sessions After Test Completion
• Loading Test Data and Environment Configuration
• Capturing Screenshots on Failure
• Generating Test Execution Logs
• Cleaning Up Temporary Resources
• Database Setup and Teardown Activities
• Framework-Level Reusable Actions

A good understanding of Hooks helps automation engineers design scalable test frameworks and avoid repetitive code. In real-world Selenium-Cucumber projects, Hooks are considered a core framework component and are commonly discussed during interviews.
