 Alternatively, you can use docker-compose to run the tests:
 
 ```console
-$ UID=$(id -u) GID=$(id -g) docker-compose -f docker-compose.testcafe.yml up
+$ UID=$(id -u) GID=$(id -g) docker-compose -f docker-compose.testcafe.yml up --exit-code-from testcafe
 ```
 
 Note: by default, tests are running in Chrome locally and in Chromium in the Docker image.
