### Model Tests
- **VideoModelTest**
  - Tests Video data class properties and equality
  - Tests WatchlistItem data class properties and equality

- **CustomerDataApiReturnTypesTest**
  - Tests conversion of CustomerPurchasedContent to AmazonContentEntitlement
  - Tests conversion of CustomerRentedContent to AmazonContentEntitlement
  - Tests conversion of CustomerRecordedContent to AmazonContentEntitlement
  - Tests conversion of CustomerListEntry to AmazonCustomerListEntry
  - Tests conversion of CustomerSubscriptionEntitlement to AmazonSubscriptionEntitlement
  - Tests conversion of CustomerTitleWatched to AmazonPlaybackEvent
  - Tests enum conversions for MyPlaybackState and MyEntitlementType

## Instrumentation Tests

- **MainActivityTest**
  - Tests that MainActivity shows SignInFragment when not logged in
  - Tests that MainActivity shows VideoBrowserFragment when logged in
  - Tests the FragmentReplacementListener functionality

## Infrastructure Changes

- Added necessary test directories (`test` and `androidTest`)
- Updated `build.gradle` with additional testing dependencies:
  - Mockito for mocking dependencies
  - PowerMock for mocking static methods
  - AndroidX Test libraries for instrumentation tests
  - Architecture Components testing for LiveData testing
- Modified `AccountRepository` to make it testable by adding a method to set the instance for testing

## Future Improvements

- Add more instrumentation tests for fragments and UI components
- Add integration tests for the interaction between components
- Implement code coverage reporting to identify areas that still need testing
- Add UI tests using Espresso for testing user interactions

> I need to work with the Leanback Library for an Amazon FireTV App that I'm building. Where should I start?

To start working with the Leanback Library for your Amazon FireTV App, I'll guide you through the essential steps:

The Leanback Library is part of the Android TV support libraries specifically designed for creating TV-optimized interfaces, which is perfect for your FireTV app.

Here's how to get started:

1. Set up your development environment:
   • Make sure you have Android Studio installed
   • Install the necessary SDK components for TV development

2. Create a new Android TV project:
   • In Android Studio, create a new project with the "Android TV Activity" template
   • This automatically includes the Leanback dependencies

3. Add Leanback Library dependencies to your existing project:
   • Open your app's build.gradle file and add:

gradle
dependencies {
    // Leanback library
    implementation 'androidx.leanback:leanback:1.0.0'
    
    // Optional but recommended for Leanback apps
    implementation 'androidx.leanback:leanback-preference:1.0.0'
    implementation 'androidx.leanback:leanback-paging:1.0.0'
}

4. Configure your AndroidManifest.xml:
   • Ensure your app is marked as a TV app
   • Add required Leanback theme

xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.yourapp">
    
    <uses-feature
        android:name="android.hardware.touchscreen"
        android:required="false" />
        
    <uses-feature
        android:name="android.software.leanback"
        android:required="true" />
        
    <application
        android:banner="@drawable/app_banner"
        android:theme="@style/Theme.Leanback">
        
        <!-- Activities -->
        <activity
            android:name=".MainActivity"
            android:theme="@style/Theme.Leanback">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LEANBACK_LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

5. Implement key Leanback components:
   • BrowseFragment: Main navigation interface
   • DetailsFragment: For showing detailed content
   • PlaybackFragment: For media playback
   • SearchFragment: For search functionality

6. Follow Fire TV specific guidelines:
   • Optimize for D-pad navigation
   • Implement proper focus handling
   • Design for 10-foot UI experience

Would you like me to provide a simple code example for implementing a basic BrowseFragment to get you started with the UI structure?
