Complete ML Pipeline Integration Tests

Tests the full machine learning pipeline from data loading through model training,
|

evaluation, and deployment. These tests validate the end-to-end functionality

without mocking any components.
|
|
|
|
## Test Categories
|
|
|
|
1. **Data Loading Pipeline**: Dataset loading, preprocessing, validation
|
|
2. **Training Pipeline**: Model training with real convergence
|
|
3. **Evaluation Pipeline**: Model evaluation and metrics computation
|
|
4. **Deployment Pipeline**: Model deployment and inference serving
|
|
5. **Multi-GPU Distributed Training**: Scaled training across devices
|
|
6. **Model Compression and Deployment**: Quantization, pruning, deployment
|
|
7. **Real-world Workload Simulation**: Production-like scenarios
|
|
|
|
## TDD Approach
|
|
|
|
Each test follows the pattern:
|
|
1. Write failing test that expects complete pipeline functionality
|
|
2. Execute full pipeline with real data and models
|
|
3. Validate results meet production quality requirements
|
|
4. Assert performance characteristics (latency, throughput, accuracy)
