What type of testing can be automated to improve testing efficiency and coverage?

• A. Exploratory testing
• B. Static analysis
• C. Manual testing
• D. Regression testing

Answer: (D)

Regression testing is a type of testing that can be effectively automated to enhance both efficiency and test coverage. The primary purpose of regression testing is to verify that recent changes or additions to the software have not adversely affected existing functionalities. Automation facilitates this by allowing tests to be executed frequently and consistently without requiring manual intervention each time. The nature of regression testing often involves running the same set of tests across various builds or releases of the software. Automating these tests saves significant time and resources, enabling testers to focus more on new features and other high-priority testing areas. Additionally, automated regression tests can be run overnight or at scheduled intervals, ensuring that any issues are caught early in the development cycle. In contrast, exploratory testing relies heavily on human intuition, creativity, and experience to discover defects. It is not well-suited for automation as it involves testing without predefined scripts or expectations, focusing on unscripted scenarios. Static analysis is a method that examines the code without executing it, which typically does not lend itself to the same automation processes as regression testing might. While tools can assist in static analysis, the approach itself is fundamentally different. Manual testing emphasizes human execution of test cases, which is necessary for certain types of tests but is generally slower and less consistent compared
