Software Quality Assurance Practice Exam

Should test cases be written for both valid and invalid input conditions?

1. True

2. False

The correct answer is: True

Writing test cases for both valid and invalid input conditions is essential in the software testing process. This approach ensures comprehensive coverage of how the application handles a variety of scenarios. Valid input test cases are designed to verify that the application functions correctly when provided with appropriate data. These cases help confirm that the system performs as expected under normal operating conditions. Conversely, invalid input test cases are equally important as they evaluate the system’s robustness and error-handling capabilities. By testing how the application reacts to unexpected or erroneous data, testers can identify vulnerabilities or weaknesses. This aspect of testing is crucial in ensuring that the software can handle misuse gracefully without crashing or producing inaccurate results. Together, these test cases contribute to a robust quality assurance strategy by confirming both functionality and security, leading to a more resilient and user-friendly application. Skipping either valid or invalid conditions would result in inadequate testing that could overlook potential issues, compromising the overall quality of the software.
