Watch Now Movie Sample with Android Architecture Components

This is a sample movie app that uses Android Architecture Components with Dagger 2.

Introduction

Functionality

The app is composed of 2 main screens.

MovieFragment

Allows you to search movies on themoviedb. Each search result is kept in the database in Movie table.

Each time a new page is fetched, the same Movie record in the Database is updated with the new list of repository ids.

NOTE The UI currently loads all Movie items at once, which would not perform well on lower end devices. Instead of manually writing lazy adapters, we've decided to wait until the built in support in Room is released.

SimilarFragment

This fragment displays the details of a move and its similars.

Building

You can open the project in Android studio and press run.

Testing

The project uses only instrumentation tests that run on the device. To run and generate a coverage report, you can run:

./gradlew fullCoverageReport (requires a connected device or an emulator)

Device Tests

UI Tests

The projects uses Espresso for UI testing. Since each fragment is limited to a ViewModel, each test mocks related ViewModel to run the tests.

Database Tests

The project creates an in memory database for each database test but still runs them on the device.

Local Unit Tests

ViewModel Tests Each ViewModel is tested using local unit tests with mock Repository implementations.

Repository Tests

Each Repository is tested using local unit tests with mock web service and mock database.

Webservice Tests

The project uses MockWebServer project to test REST api interactions.
