Tosca Unattended Execution enables you to execute graphical user interface tests with a locked screen. For example, you can use it to test keyboard or mouse operations without a user logged in to the agent computer.

When a Tosca Distribution Agent configured for unattended execution receives a test to execute, the Tosca RDP Server opens a remote desktop (RDP) connection to the agent. The Tosca RDP Server runs as a service on the same machine as the Tosca Distribution Agent. Once the agent has executed the test, the system closes the RDP connection.

To configure a Tosca Distribution Agent for unattended execution, set the following in addition to the mandatory agent configurations.

2. Go to Computer Configuration->Administrative Templates->Windows Components.

3. Select Remote Desktop Services->Remote Desktop Session Host->Security.

4. Open Always prompt for password upon connection.
