+## Running Tests on Another Machine
+
+To run tests on a target connected to another machine (e.g., in a GitLab CI pipeline), follow these steps:
+
+### On the Host Machine
+
+Set up a J-Link tunnel to make the target accessible from anywhere:
+
+```shell
+JLinkRemoteServerCL -UseTunnel -TunnelBySN
+```
+
+The terminal output should look like this:
+
+```
+2025-06-04 08:43:57 - Remote Server started
+2025-06-04 08:43:57 - Connected to J-Link with S/N 801000372
+2025-06-04 08:43:57 - Resolving tunnel server name (jlink-europe.segger.com)...
+2025-06-04 08:43:57 - Tunnel server IP: 185.162.249.2
+2025-06-04 08:43:57 - Registered at tunnel server
+2025-06-04 08:43:57 - Waiting for client connection
+```
+
+`801000372` is the tunnel ID required to reach the target. Include it in your CMake command:
+
+```shell
+cmake --preset Test -DTUNNEL_ID=801000372
+```
+
+When you run the tests, they will automatically execute on the host machine.
