Test cases are an important part of software testing that help verify whether an application works as expected or not. A well-written test case includes inputs, execution steps, expected results, and actual outcomes to ensure software quality and reliability.

In software development, test cases help QA teams identify bugs, improve test coverage, and validate application behavior under different scenarios. They are commonly used in manual testing as well as automation testing workflows.

A good test case should be clear, reusable, easy to understand, and focused on a specific functionality. Common types include positive test cases, negative test cases, boundary value test cases, and regression test cases.
