Model-View-Presenter application with Kotlin

A simple Android app in Kotlin that shows a list of trending repositories on Github and a detail of each one when clicked. The selected architecture for the project was MVP (Model-View-Presenter)

Libraries

• Dagger2 for dependency injection
• Retrofit2 for networking handling
• RxJava2 for async operations
• Moshi for JSON parsing
• Mockito for mocking on tests
• And MarkDownView and CircleImageView for the UI

Tests

Unit tests

Added unit tests for both GithubTrendsPresenter and RepoDetailPresenterTest. Used Mockito to mock the view and the data manager (API calls).

UI Tests

Used Espresso to run UI tests on both GithubTrendsActivity and RepoDetailActivity.

Taken decisions

• The search is done on the already searched items. It does not perform a new search within the API
• The trending topic search query is 'android', so it will show the trending repositories on Android

Improvements

• Unify mock classes for both tests suites (instead of having one for unit tests and other for UI tests)
• Custom message handler for possible Retrofit network responses
• When searching and scrolling down the app will make an API call to get more repos
