# 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.
* Choose **'Nested Test Case'** from the available options.
* Select the required test case to call, then click **'Confirm Selection'** to proceed.
* The **Branches View** is also available within the **Nested Test Data** section to view and manage the associated branches and their datasets.
