Software Quality Assurance Practice Exam

Which of the following are components of a test case?

1. A description of data processing information

2. A description of the correct output of the program for a given set of input data

3. A description of the input data to the program

4. A description of the type of testing technique used

The correct answer is: A description of the correct output of the program for a given set of input data

A test case is a fundamental component in the software testing process, designed to validate that a specific requirement or functionality works as intended. One critical element of a test case is a description of the correct output of the program for a given set of input data. This helps testers determine whether the application behaves correctly by comparing the actual output with the expected output during testing. Providing this expected output allows testers to effectively evaluate the software's performance and ensures that it meets defined requirements. Essentially, it acts as a reference point, enabling accurate assessments of whether the application is functioning as it should. While the other components listed can play roles in the broader context of testing, they do not specifically define what a test case entails. For instance, while describing input data is important for understanding how to execute a test case, it does not define the outcome that is being verified. Similarly, the type of testing technique or data processing information relates to the overall testing strategy rather than the specific test case itself.
