What type of testing is done to supplement the rigorous testing?

  1. Regression testing.

  2. Integration testing.

  3. Error Guessing.

  4. System testing.


Correct Option: C

AI Explanation

To answer this question, you need to understand different types of testing and their purposes.

Option A) Regression testing - Regression testing is performed to ensure that changes or updates to the software do not introduce new defects or impact existing functionality. It is not directly related to supplementing rigorous testing.

Option B) Integration testing - Integration testing is done to test the interaction between different components or modules of the software. It focuses on identifying defects that arise due to the integration of these components. It is not specifically done to supplement rigorous testing.

Option C) Error Guessing - Error guessing is a technique where testers use their experience and intuition to identify potential defects without specific test cases. It is a type of black-box testing and can be used to supplement rigorous testing by exploring areas that may not have been covered in the planned test cases.

Option D) System testing - System testing is performed to evaluate the complete and integrated system against the specified requirements. It is not specifically done to supplement rigorous testing.

The correct answer is option C) Error Guessing. This option is correct because error guessing can be used as an additional technique to supplement rigorous testing by allowing testers to use their experience and intuition to identify potential defects.
