Ques 21. Explain the concept of 'dependency injection' and its relevance in test automation.
Dependency injection involves providing a component with its dependencies rather than letting it create them. In test automation, it helps in creating more modular and testable code.
Example:
Injecting a WebDriver instance into a page object rather than creating it within the page object class.
Ques 22. How do you handle test environment configurations in automated testing?
Using configuration files or environment variables to store and manage test environment configurations ensures tests can be executed in different environments with minimal code changes.
Example:
Storing URL, database connection strings, and other configurations in a properties file.
Ques 23. What is the purpose of a test strategy, and how does it differ from a test plan?
A test strategy outlines the overall testing approach, while a test plan details the specific testing activities for a particular project or release. The strategy provides a high-level view of testing objectives, scope, and resources.
Example:
Creating a test strategy document that outlines the approach for functional, performance, and security testing.
Ques 24. How can you ensure the maintainability of automated test scripts?
Ensuring proper code organization, using meaningful variable and method names, and implementing coding standards contribute to the maintainability of automated test scripts.
Example:
Regularly refactoring test code to improve readability and maintainability.
Ques 25. What is the purpose of a test harness in software testing?
A test harness is a set of tools, libraries, or software that facilitates the execution of tests. It provides an environment for running and analyzing tests, collecting results, and managing test configurations.
Example:
Using JUnit or TestNG as a test harness for Java-based test automation.
