Which of these testing types is not part of system testing?
Show answer Hide answer
Answer: D. Random testing
Explanation
Random testing is an execution technique rather than a specific type of system testing like recovery or stress. System testing categories include recovery security stress and performance testing addressing specific quality attributes. Random testing generates inputs probabilistically to uncover unexpected software failures across modules. System testing evaluates the complete integrated software product against operational and non functional requirements. Stress testing pushes the system beyond normal limits to evaluate robustness and failure recovery behavior. Random testing provides a statistical approach to uncovering obscure bugs without biased test case creation.
Quality assurance engineers design specialized system testing suites to evaluate fault tolerance and security. Enterprise applications undergo rigorous stress testing before public deployment to ensure high availability. Random testing is often used alongside fuzzing techniques to discover security vulnerabilities in software. Recovery testing is a recognized system testing type designed to evaluate how well software recovers from crashes. Stress testing is a formal system testing category that evaluates performance under extreme resource loads. System testing itself describes the overarching testing phase rather than being a non system testing technique.
