• Test with Callbacks Callbacks inside Test, app works, but test does not wait for callbacks to complete. (Dangerous!!!)
• Test with Done Callback Jasmine Done callback (https://jasmine.github.io/tutorials/async#callbacks)
• Test with Angular waitForAsync Angular waitForAsync (https://angular.io/api/core/testing/waitForAsync)
• Test with async/await async/await pattern (https://jasmine.github.io/tutorials/async#asyncawait)
