What is the primary goal of a test case?

The primary goal of a test case is to identify defects in the software being tested. A test case is a document that outlines the conditions and criteria under which a particular functionality of the software will be tested. It describes the input, execution steps, and expected outcomes. By rigorously implementing these test cases, testers systematically evaluate the software for compliance with the specified requirements and the potential for faults.

Identifying defects is essential because it allows the development team to address issues before the product is released, ensuring a higher quality product. The test case guides the tester in a structured manner, increasing the chances of uncovering defects that need resolution. This focus on defect identification is a critical component of software testing, as it directly contributes to the overall reliability and robustness of the final product.
