The Application is fully written in : Kotlin

• Junit5
• Mockk
• CoroutinesTest
• Ktor Client Test

• Tools and General setup

• Gradle secrets plugin
• Hilt - For Dependency injection
• Timber - For viewing logs
• Ktlint

• Workflows

• The app has a (github action workflow)[https://github.com/chepsi/weather-app/actions] to run tests and build the application once a PR is raised against the main branch

Architecture

• For the Presentation Layer I used MVVM. I have the MainScreen, MainViewModel and MainScreenState

• Generally I used clean architecture to Separate the different layers of the application as outlined above
