Testing RTMP Data Source Integration in SmartTube ExoPlayer Extension

This test suite validates the DefaultDataSource implementation for handling RTMP (Real-Time Messaging Protocol) URIs in the SmartTube ExoPlayer extension. It focuses on verifying proper instantiation of RTMP data sources through reflection mechanisms.

Test Coverage Overview

The test coverage focuses on the essential functionality of RTMP URI handling in DefaultDataSource. Key areas tested include:

RTMP URI parsing and validation
DataSource instantiation via reflection
Error handling for unsatisfied link and unsupported operation scenarios

Implementation Analysis

The testing approach employs JUnit 4 with AndroidJUnit4 runner for Android-specific context testing. The implementation uses reflection-based instantiation patterns to create RTMP data sources dynamically, with specific error handling for different build environments (Gradle vs Blaze).

Technical Details

Testing tools and configuration include:

JUnit 4 testing framework
AndroidJUnit4 test runner
ApplicationProvider for context access
DataSpec for URI specification
DefaultDataSource implementation testing

Best Practices Demonstrated

The test suite demonstrates several testing best practices:

Isolated test cases with clear purpose
Proper exception handling for different runtime environments
Use of appropriate Android testing utilities
Clean and focused test method naming
