# Test File Server

After saving a file or mock in File Server, you can use the built-in **Test** action to verify that the response matches your expectations.

**1. Open the JSON file**

Open the JSON file from the list of files available in the files Dashboard.

In the top header of the JSON file, click the Test button to initiate the testing process.

A dialog box will open with the endpoint URL field and the request method already pre-populated in the user interface for your convenience.

**4. Send the Request**

Click the **Send** button to trigger the request and view the response. The response body and headers returned from the file will be displayed in the interface.

This confirms that the JSON is served as expected and can now be integrated into your application for further use.
