Fault base testing technique is _____________.

Correct option is D

Mutation testing is a fault-based testing technique where small changes (mutations) are introduced to a program's source code to evaluate the effectiveness of test cases. The objective is to ensure test cases can detect these faults.
Information Booster:
1. Purpose: To check the quality of test cases by introducing deliberate errors and ensuring they are detected.
2. Mutants: Altered versions of the program created by introducing changes like replacing operators or modifying statements.
3. Kill the Mutant: A test case is successful if it detects the mutation.
4. Advantage: Identifies gaps in test coverage and ensures robustness.
5. Limitation: Can be computationally expensive for large programs.
Additional Knowledge:
· Unit testing focuses on testing individual components.
· Beta testing is performed by end users in real environments.
· Stress testing checks system performance under extreme conditions.
