Let's run all the tests to make sure the generated test code works fine.
Let's run the server-side unit/integration tests, client-side Karma 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. Make sure you have the application running, as e2e tests will need it. If the application is not running first start it by running ./gradlew in a Terminal:
> ./gradlew test && yarn test && yarn e2e
