# Code (Repository to Test Case)

The **Code** option within the Intelligence Hub allows you to generate structured **test cases** directly from your application's source code. This feature analyzes your connected repository to understand the application's functionality and generate relevant test scenarios, eliminating the need to manually create test cases from existing application behavior.

**When to Use Code-Based Test Case Generation**

Use this option when your application's functionality is already available in a connected source code repository. WalnutAI analyzes the repository and automatically generates structured **test cases**, making it useful for documenting and testing existing applications, legacy systems, or projects with limited test documentation.

* **Existing Connection:** If a repository was configured during project setup (**GitHub, GitLab, Bitbucket, Azure Repos, or AWS CodeCommit**), it will automatically appear under the **Code** option in the Intelligence Hub.
* **Open the Code Repository:** Click the **Code** icon in the Intelligence Hub to view the list of available repositories.
