Question 92: What is the primary goal of model-based testing?
A) To evaluate the software's ease of use and user experience
B) To generate test cases automatically from models of the software's behavior
C) To assess the software's ability to recover from crashes and hardware failures
D) To simulate real-world cyber attacks to identify weaknesses in the system
Explanation: Model-based testing involves generating test cases automatically from models of the software's behavior, improving test coverage and reducing the effort required for test case design and maintenance.
Question 93: Which testing technique involves simulating real-world usage scenarios to identify defects and validate the software's functionality?
A) Load testing
B) Stress testing
C) Endurance testing
D) Scenario-based testing
Explanation: Scenario-based testing involves simulating real-world usage scenarios, user interactions, and workflows to identify defects and validate the software's functionality against user requirements.
Question 94: What is the purpose of mutation testing?
A) To identify and fix security vulnerabilities in the source code
B) To evaluate the software's ease of use and user experience
C) To assess the effectiveness of the existing test cases by introducing small changes (mutations) to the source code
D) To simulate real-world cyber attacks to identify weaknesses in the system
Explanation: Mutation testing involves introducing small changes (mutations) to the source code to assess the effectiveness of the existing test cases in detecting these changes, helping to improve test coverage and reliability.
Question 95: Which testing technique is used to assess the software's performance under normal and peak load conditions?
A) Boundary testing
B) Endurance testing
C) Scenario-based testing
D) Load testing
Explanation: Load testing evaluates the software's performance under normal and peak load conditions by simulating multiple users or transactions, helping to identify performance bottlenecks and scalability issues.
Question 96: What is the primary objective of usability testing?
A) To evaluate the software's ease of use and user experience
B) To identify defects in the source code and improve code quality
C) To simulate real-world cyber attacks to identify weaknesses in the system
D) To assess the software's ability to recover from crashes and hardware failures
Explanation: Usability testing evaluates the software's ease of use, user interface design, and overall user experience to ensure that it meets the needs and expectations of its intended users.
Question 97: Which testing technique is focused on evaluating the software's ability to handle unexpected or random inputs?
A) Boundary testing
B) Equivalence partitioning
C) Decision table testing
D) Fuzz testing
Explanation: Fuzz testing involves providing unexpected or random inputs to the software to identify vulnerabilities, buffer overflows, and other security issues caused by unexpected data.
Question 98: What is the primary goal of regression testing?
A) To evaluate the software's performance under normal and peak load conditions
B) To identify defects in the source code and improve code quality
C) To ensure that recent changes or updates to the software do not adversely affect existing functionality
D) To simulate real-world cyber attacks to identify weaknesses in the system
Explanation: Regression testing verifies that recent changes or updates to the software do not adversely affect existing functionality by retesting the affected areas and ensuring that previously working features still work as expected.
Question 99: Which testing technique focuses on evaluating the software's ability to handle different combinations of inputs and conditions?
A) Boundary testing
B) Equivalence partitioning
C) Decision table testing
D) Combinatorial testing
Explanation: Combinatorial testing involves evaluating the software's behavior by testing different combinations of inputs, configurations, and conditions to uncover defects that may occur due to interactions between variables.
Question 100: What is the purpose of acceptance testing?
A) To validate whether the software meets specified requirements and user expectations
B) To evaluate the software's ease of use and user experience
C) To assess the software's performance under normal and peak load conditions
D) To simulate real-world cyber attacks to identify weaknesses in the system
Explanation: Acceptance testing validates whether the software meets specified requirements and user expectations, typically performed by end users or stakeholders to determine if the software is ready for deployment.
