 ## 🧪 Testing
 For this project, **unit**, **integration**, **end-to-end** tests have been written based on the pyramid test in the Android test [codelab](https://developer.android.com/codelabs/advanced-android-kotlin-training-testing-test-doubles#2), and in addition,
 a **benchmark** test has been written for the app startup states to measure the effectiveness of using the Baseline Profile.
