# Nested Test Case

**Nested Test Cases** are reusable test cases that are called and executed within another parent test case as part of its workflow.

They allow you to embed a predefined set of steps (such as login, setup, or validation flows) that are used frquently inside a larger test scenario, enabling modular, reusable, and maintainable test design.

* **Nested Test Case:** To add a nested test case, hover over the desired test step and click the branching icon.
