# Manage Test Data of a Test Case

**Test Data** refers to the set of input values and parameters used to execute a test case and validate system behaviour. Proper test data ensures accurate, consistent, and repeatable test execution.

Test Data Management in WalnutAI consists of [**Test Data**](#user-content-fn-1)[^1] and [**Nested Test Data**.](#user-content-fn-2)[^2]

* The Test Data section is specific to an individual test case, allowing you to define the exact values as per the test case which will be used during execution.&#x20;

  * To add a dataset in a test case open the test case > Test Data and click '**Add Dataset'** and enter parameter values (such as URL, Email, or Password). All fields are editable and can be customized based on your test requirements.
  * Use the '**Import'** option to upload external datasets if they are already available.
  * Click '**Export'** to download the existing datasets for external use.
  * After adding or updating data, click '**Save All'** to ensure the datasets are stored and ready for execution.

{% hint style="info" %}
Test cases created using **Smart Recording from the Intelligence Hub** will have parameters automatically identified and mapped.
{% endhint %}

* **Nested Test Data** section applies to nested test cases (reusable test cases executed within other test cases).

  * **Left Panel:** Displays the nested test case structure (branches).
  * **Right Panel:** Shows parameter values and datasets for the selected branch.

{% hint style="info" %}
If multiple datasets exist, select the required ones using the checkbox to make it as Default which will be used for execution; otherwise, the system defaults to the first dataset. When multiple datasets are selected, the platform performs **Iterative Execution**, running the test once per selected dataset.
{% endhint %}

[^1]: Test Data is the input you give to a test case to check if the system works correctly.

[^2]: Nested Test Data is the input used for a nested (reusable) test case that runs inside another test case.
