# Setting up a UDC test connection

In order to test the different web services (server and client) and to improve the stability of the spot via local data, it is possible to set up test connections. The corresponding parameters must be defined correctly and in part, have a limited validity.

Note

To secure a correct operation of the spot, the spot developer must ensure that the spot

- is tested against all web services (server and client)
- is transferred to all corresponding player types and the playback is tested (players have different web engines and therefore exhibit differing behavior).

The test connection is set up via the setLocalTestData function (see setLocalTestData). Below, the determination of the parameters as well as the creation of a local data file under the use of the browser developer tools is explained.

## Using developer tools

The required values can be read out via the developer tools of the browser.

Note

We recommend Google Chrome. However, it's possible to use other browsers.

It is recommended, to permanently deactivate the browser cache and to filter the display of the requests as specified in the following image:

7. Code: Use the above value for DebugClient.siid.

### Creating local test data

In order to test the spot against local data, establish an initial test connection to the web services, optionally via server or client. For this, the corresponding data sources are accessed.

Following this, complete the steps below:

1. Browser: Open the spot in the browser via the ascInterface.
2. Developer tools: Open the developer tools via the keyboard shortcut CRTL+SHIFT+I.
3. Developer tools: Switch to the **Network** tab.
4. Developer tools: Identify the UDC request:
  - It starts with a distinct description (e.g. "News").
  - If there are two entries available, select the entry with the larger file size (it contains the data). ![A screenshot of a computer Description automatically generated with medium confidence](https://cdn.document360.io/e2b87f73-d9f5-43cb-8182-2641762664fd/Images/Documentation/setting-up-a-udc-test-connection-image-7kak4oge.png?sv=2026-02-06&spr=https&st=2026-11-06T20%3A17%3A52Z&se=2026-11-06T21%3A17%3A52Z&sr=c&sp=r&sig=shTAopcABl3OMk1l4K8gOsOdMA9QRHuO0eGyPMbhtg8%3D)
5. Developer tools: Click on the request in order to show the **Details** pane on the right.
6. Developer tools: Switch to the **Response** tab and copy its entire content to the clipboard. ![A screenshot of a computer Description automatically generated with medium confidence](https://cdn.document360.io/e2b87f73-d9f5-43cb-8182-2641762664fd/Images/Documentation/setting-up-a-udc-test-connection-image-xv8xilj0.png?sv=2026-02-06&spr=https&st=2026-11-06T20%3A17%3A52Z&se=2026-11-06T21%3A17%3A52Z&sr=c&sp=r&sig=shTAopcABl3OMk1l4K8gOsOdMA9QRHuO0eGyPMbhtg8%3D)
7. Code: Create a new JSON file in the spot project (e.g. udc.json).
8. Code: Insert the content of the clipboard in the previously created file and save it.

### Linking local test data

The JSON file created with local test data in the spot project can now be used as follows:

```xml
var udc = new GFUdcConnector();
var connection = {
   url: "./udc.json"};
udc.setLocalTestData(connection);
// fetch some data...
```

Using local test data allows for a simple and convenient way to develop the spot against a static server and client solution. Further, it is possible to quickly modify the data and simulate various scenarios.
