    Question

    Which of the following testing types focuses on

    validating that a system meets its functional requirements?
    A Unit Testing Correct Answer Incorrect Answer
    B Integration Testing Correct Answer Incorrect Answer
    C System Testing Correct Answer Incorrect Answer
    D Regression Testing Correct Answer Incorrect Answer
    E Acceptance Testing Correct Answer Incorrect Answer

    Solution

    System Testing evaluates the complete and integrated system to ensure it meets the specified functional requirements. This black-box testing technique checks the system's overall behavior, ensuring it performs as intended in various scenarios. System testing is conducted after integration testing and focuses on validating functional and non-functional requirements like usability, reliability, and performance. System testing is critical in identifying defects that arise from system-level interactions, ensuring the software delivers expected results before deployment. Why Other Options Are Incorrect: 1. Unit Testing: Focuses on individual components or modules, not the entire system. 2. Integration Testing: Tests interactions between integrated modules but not the full system. 3. Regression Testing: Ensures new changes do not disrupt existing functionality but does not validate functional requirements. 4. Acceptance Testing: Validates the system against user needs and business requirements but is the final step before release. System testing ensures comprehensive validation of functional requirements, making it a cornerstone of software quality assurance.
