• Leverage JavaScriptExecutor to interact with dynamic elements directly.

7. What are the best practices for writing maintainable automation test scripts?

• Use a modular and reusable design for test scripts.
• Follow naming conventions and documentation standards.
• Employ error handling and logging mechanisms to capture and report errors effectively.
• Use version control systems to manage and track changes to test scripts.

8. How do you ensure the stability of automated tests in a continuous integration environment?

• Use a stable and reliable test environment for automation.
• Implement proper version control for test scripts and test data.
• Employ regular regression testing to identify and fix any broken tests promptly.
• Use monitoring and alerting tools to track test execution and receive notifications of failures.

9. Explain the role of artificial intelligence (AI) in automation testing.

• AI techniques like machine learning and computer vision can enhance test automation.
• AI algorithms can analyze test data and identify patterns for intelligent decision-making.
• AI-driven test automation tools can automatically generate test cases and optimize test execution.

10. What are the future trends in automation testing?

• Increased adoption of AI and machine learning in test automation.
• Shift towards low-code/no-code automation testing tools.
• Integration of automation testing with DevOps practices.
