Testing and Validation
Testing: Testing involves executing the software or system under controlled conditions to identify defects or errors. It aims to verify that the product behaves as expected and meets the defined requirements. Testing can include various activities such as:
- Unit Testing: Testing individual components or modules of the software in isolation to ensure they function correctly.
- Integration Testing: Testing the interaction between different components or modules to verify that they work together as intended.
- System Testing: Testing the entire system as a whole to validate its functionality and performance.
- Acceptance Testing: Testing conducted by end-users or stakeholders to determine whether the system meets their requirements and expectations.
- Regression Testing: Repeatedly testing the system after making changes to ensure that existing functionalities have not been affected.
Validation: Validation is the process of evaluating the final product to ensure that it meets the user's needs and requirements. It verifies that the product fulfills its intended use in its intended environment. Validation often involves comparing the product against the initial requirements and conducting user acceptance testing to ensure it meets user expectations.
