 Testing is performed automatically in Github Actions when a PR is submitted. To execute tests locally before submitting a PR, you'll need [Docker and Docker Compose](https://docs.docker.com/engine/install/).
 
 Configure your test environment:
+
 ```
-export PHP_VERSION=8.1
-export DRUPAL_VERSION=10
+export PHP_VERSION=8.4
+export DRUPAL_VERSION=11
 export DOCKER_USER_ID=${UID}
 ```
 
 Prepare environment for testing:
+
 ```
-docker-compose up -d
-docker-compose exec -T php composer self-update
-docker-compose exec -u ${DOCKER_USER_ID} -T php composer require --no-interaction --dev --no-update drupal/core:^${DRUPAL_VERSION}
-docker-compose exec -T php composer install
+docker compose up -d
+docker compose exec -T php composer self-update
+docker compose exec -u ${DOCKER_USER_ID} -T php composer require --no-interaction --dev --no-update drupalcore:^${DRUPAL_VERSION}
+docker compose exec -T php composer install
 ```
 
 Execute all tests:
+
 ```
-docker-compose exec -T php composer test
+docker compose exec -T php composer test
 ```
 
 Execute specific tests, eg just PHPUnit's Drupal7FieldHandlerTest:
+
 ```
-docker-compose exec -T php phpunit --filter Drupal7FieldHandlerTest
+docker compose exec -T php phpunit --filter Drupal7FieldHandlerTest
 ```
 
 - Check the changes from `composer require` are not included in your submitted PR.
