Let's run all the tests to make sure that the generated test code works fine.
Let's run the server-side unit/integration tests, client-side Jest unit tests, and Protractor e2e tests using the command line. In a new Terminal, navigate to the application source folder and execute these commands. They should finish with a success message:
> ./gradlew test integrationTest && npm test && npm run e2e
Make sure you have the application running, as e2e tests will need it. If the application is not running, then first start it by running ./gradlew in a Terminal.
