Write A 200 To 300 Word Short Answer Response To The Following When

Write a 200- to 300-word short-answer response to the following: When verifying code, test values must be chosen that fully exercise the code. Those results have to be compared to the expected result in order to determine if the test passed or failed. Discuss the process of choosing test values and determining the expected result. What types of considerations come into play? What is the criteria for a good test?

Paper For Above instruction

When verifying code, selecting appropriate test values and determining expected outcomes are critical steps to ensure that software functions as intended. The process begins with understanding the code’s purpose and identifying various input scenarios that the program might encounter during normal and edge cases. Test values should be chosen to thoroughly exercise all possible paths through the code, including typical inputs, boundary conditions, and invalid or unexpected inputs. For example, if a function handles different ranges of values, testers should include those at the edges of each range to confirm proper handling.

Deciding on the expected result involves analyzing the code’s logic and specification to predict correct outputs for each test input. This requires careful attention to detail and a clear understanding of functional requirements. Considerations such as data types, input constraints, and handling of special cases influence the expected outcomes. Additionally, test values should encompass both “happy path” scenarios, where everything works as expected, and “fault injection” scenarios, which deliberately trigger errors to test robustness.

A good test possesses several criteria: it is repeatable, easy to understand, and comprehensive enough to cover key aspects of the code’s functionality. It should be designed to detect both errors in common cases and edge cases where bugs are more likely to occur. Overall, effective testing hinges on thoughtful selection of test inputs and precise expectation setting, ensuring confidence in the correctness and reliability of the software.
