# Test Cases

A Test Case in Walnut is a structured validation unit designed to verify that an application behaves as expected. It defines a clear sequence of steps, associated objects, expected outcomes, and supporting test data to ensure functional accuracy and requirement compliance. This structured approach enables consistency, traceability, and reliable validation across the application.

In this module, you will learn how to create a test case, manage its test data effectively, build nested test cases, implement conditional workflows (such as If/Else and loops), execute test cases, and leverage AI Healing to automatically detect and resolve UI or object-level changes during execution.
