+Nevertheless, if your code can be unit tested, please provide a unit test (we use Jasmine), or an end-to-end test (we use Testcafe).

+* if the features can be automatically tested, please provide a testcafe test
+
+#### Running testcafe tests
+
+End-to-end tests are available in the "/tests" directory.
+
+To run these tests locally:
+
+```console
+$ LIVE_RELOAD=0 docker-compose up -d
+$ cd tests
+$ npm install
+$ npm run test
+```
+
+Note: If your tests fail on a Javascript error in "sockjs", this is due to the
+Webpack live reload. The Webpack live reload feature is conflicting with testcafe. This is why we recommend starting 
+WorkAdventure with the `LIVE_RELOAD=0` environment variable. 
+
+End-to-end tests can take a while to run. To run only one test, use:
+
+```console
+$ npm run test -- tests/[name of the test file].ts
+```
+
+You can also run the tests inside a container (but you will not have visual feedbacks on your test, so we recommend using
+the local tests).
+
+```console
+$ LIVE_RELOAD=0 docker-compose up -d
+# Wait 2-3 minutes for the environment to start, then:
+$ PROJECT_DIR=$(pwd) docker-compose -f docker-compose.testcafe.yml up
+```
