Question 1. What is the primary objective of system testing? A) To verify individual modules in isolation B) To assess the entire system's compliance with specified requirements from an end-user perspective C) To perform security vulnerability assessment only D) To check hardware compatibility exclusively Answer: B Explanation: The main goal of system testing is to evaluate the complete, integrated system to ensure it meets all specified requirements and functions correctly from the user's perspective, verifying end-to-end functionality. Question 2. How does system testing differ from unit testing? A) System testing focuses on individual components, whereas unit testing evaluates the entire system
B) System testing is performed after acceptance testing C) System testing evaluates the whole system including hardware and software, while unit testing isolates individual modules D) There is no difference between them Answer: C Explanation: System testing assesses the entire integrated system, including hardware, software, and data, whereas unit testing focuses on testing individual components separately. Question 3. Which phase follows integration testing in the V-model of software development? A) System testing B) Unit testing C) User acceptance testing
Explanation: System testing is vital because it detects issues arising from module interactions, performance bottlenecks, and security vulnerabilities that aren't apparent during earlier testing phases. Question 5. What is the purpose of defining entry and exit criteria in the system test life cycle? A) To determine when to start and stop testing activities based on predefined conditions B) To select testing tools C) To design test cases only D) To manage project documentation Answer: A Explanation: Entry and exit criteria specify the conditions that must be met to begin testing and to conclude it, ensuring systematic and controlled testing progress.
Question 6. Which methodology is used to derive test cases that cover all system requirements? A) Random selection B) Test case design based on requirements, use cases, and specifications C) Guesswork based on previous projects D) Only exploratory testing without documentation Answer: B Explanation: Effective test cases are derived systematically from requirements, use cases, and design specifications to ensure comprehensive coverage. Question 7. What is the purpose of a test traceability matrix? A) To track bugs and defects only
D) Path testing Answer: B Explanation: Equivalence partitioning divides input data into classes where the system is expected to behave similarly, a key black-box testing technique. Question 9. What does boundary value analysis primarily target? A) Testing at the edges of input ranges where errors are common B) Testing the system's response to invalid inputs only C) Checking for security vulnerabilities D) Validating user interface design Answer: A Explanation: Boundary value analysis focuses on testing values at, just inside, and just outside the boundaries of input ranges, as these are prone to errors.
Question 10. Which type of testing evaluates system responsiveness and stability under load? A) Performance testing B) Security testing C) Usability testing D) Compatibility testing Answer: A Explanation: Performance testing assesses how the system responds under various load conditions, including responsiveness, stability, and scalability. Question 11. What distinguishes load testing from stress testing? A) Load testing assesses performance under expected usage, stress testing evaluates beyond normal limits to determine breaking points
D) Data privacy validation Answer: B Explanation: Penetration testing involves simulating attacks to exploit vulnerabilities, assessing the system's security defenses. Question 13. How does usability testing contribute to system quality? A) It measures system response time under load B) It evaluates user-friendliness and overall user experience C) It checks for security flaws D) It verifies hardware compatibility Answer: B Explanation: Usability testing assesses how easy and satisfying the system is for users, focusing on UI and UX aspects.
Question 14. Which metric indicates the average time between system failures? A) Mean time to repair (MTTR) B) Defect density C) Mean time between failures (MTBF) D) Test coverage Answer: C Explanation: MTBF measures the average operational time between failures, indicating system reliability. Question 15. What is the primary goal of portability testing? A) To verify system's ability to operate across different environments and hardware configurations
Answer: A Explanation: Scalability testing assesses how well the system can grow by adding resources to support increased data or user loads. Question 17. In reliability testing, what does an increase in MTTR typically indicate? A) Improved system uptime B) Longer time to recover from failures, indicating poorer recoverability C) Higher defect density D) Better performance under load Answer: B Explanation: A longer MTTR reflects that it takes more time to repair and recover from failures, indicating reduced reliability.
Question 18. Which of the following is NOT a focus of installation testing? A) Verifying successful installation and uninstallation processes B) Testing system performance under high load C) Validating configuration and setup procedures D) Ensuring the system can be installed without issues on various environments Answer: B Explanation: Installation testing concentrates on the process of installing and configuring the system, not on performance under load. Question 19. What is the primary purpose of defect management? A) To track, prioritize, and resolve defects systematically B) To write test cases
Explanation: Jira is a popular defect management tool used to log, track, and manage bugs during testing. Question 21. How do equivalence partitions improve test efficiency? A) By reducing the total number of test cases needed to cover input data B) By increasing the number of test cases to maximize coverage C) By testing only invalid inputs D) By focusing solely on security vulnerabilities Answer: A Explanation: Equivalence partitioning groups input data into classes, allowing testers to select representative test cases and reduce redundancy. Question 22. What is the main advantage of automated test execution?
A) Slower testing process B) Reduced repeatability of tests C) Faster execution, consistency, and suitability for regression testing D) No need for test planning Answer: C Explanation: Automation speeds up test execution, improves consistency, and is especially beneficial for repeated regression tests. Question 23. Which phase involves analyzing test results and identifying defects? A) Test planning B) Test execution C) Reporting and analysis
Question 25. What does regression testing aim to ensure? A) The system's security is intact B) New changes do not adversely affect existing functionalities C) The system can handle high load D) The user interface remains consistent Answer: B Explanation: Regression testing verifies that recent changes or bug fixes haven't introduced new defects or broken existing features. Question 26. Which of the following best describes the purpose of risk-based testing? A) To test all system components equally regardless of risk
B) To prioritize testing efforts on high-risk areas to maximize defect detection efficiency C) To ignore high-risk areas in favor of low-risk features D) To conduct testing only during the final phase of development Answer: B Explanation: Risk-based testing focuses on high-risk areas to improve the likelihood of detecting critical defects within limited testing resources. Question 27. What is the key benefit of creating a requirements traceability matrix? A) It simplifies test environment setup B) It ensures all requirements are covered by test cases and facilitates impact analysis when requirements change C) It replaces the need for test case design
