Software Testing Software Testing 3 — Questions and Answers
Question 1: Which testing approach tests the interaction between integrated components or systems?
- Unit testing
- System testing
- Integration testing (Correct answer)
- Exploratory testing
Correct answer: Integration testing
Integration testing verifies that different modules or services work correctly together when combined.
Question 2: What is the primary goal of regression testing?
- To find new features in the software
- To ensure that previously working functionality still works after changes (Correct answer)
- To test the software under extreme load conditions
- To verify security vulnerabilities are fixed
Correct answer: To ensure that previously working functionality still works after changes
Regression testing ensures that new code changes have not broken existing functionality that was previously working correctly.
Question 3: What does 'MTTR' stand for in the context of software reliability testing?
- Maximum Time To Release
- Mean Time To Repair (Correct answer)
- Minimum Test To Run
- Measured Test Throughput Rate
Correct answer: Mean Time To Repair
MTTR (Mean Time To Repair) measures the average time required to repair a system after a failure occurs.
Question 4: Which testing type checks whether the software performs well under expected and peak load conditions?
- Functional testing
- Usability testing
- Performance testing (Correct answer)
- Compatibility testing
Correct answer: Performance testing
Performance testing evaluates how a system behaves in terms of speed, stability, and scalability under various load conditions.
Question 5: In a test plan, what does 'test scope' define?
- The tools used for test execution
- What will and will not be tested (Correct answer)
- The schedule for test execution
- The number of testers required
Correct answer: What will and will not be tested
Test scope defines the boundaries of testing by specifying which features and functions will be included or excluded from the test effort.
Question 6: What is the difference between verification and validation in software testing?
- Verification checks code syntax; validation checks logic
- Verification checks if we built it right; validation checks if we built the right thing (Correct answer)
- Verification is automated; validation is manual
- Verification is done by developers; validation is done by customers only
Correct answer: Verification checks if we built it right; validation checks if we built the right thing
Verification ensures the product is built correctly per specifications, while validation ensures the right product is built to satisfy user needs.
Question 7: Which test design technique is most suitable for testing systems with multiple input conditions and their combinations?
- Boundary value analysis
- State transition testing
- Decision table testing (Correct answer)
- Use case testing
Correct answer: Decision table testing
Decision table testing is ideal for systems with complex combinations of conditions and actions, ensuring all combinations are considered.
