Test Case

A test case is a detailed plan used to check whether a software or system works as expected. It outlines specific conditions, inputs, and steps to perform, along with the expected outcomes. By following a test case, testers can verify that different features function correctly and identify any errors or issues. Think of it like a checklist used to ensure all parts of a machine are operating smoothly. Test cases help developers improve quality, reliability, and user experience by systematically evaluating the software’s performance in various scenarios.
