- Added locked standardized testing sections to autograd and optimizers modules
- Fixed kernels module structure to match optimizers/training pattern
- Added comprehensive VS Code setup guide for Jupytext editing
- All 12 TinyTorch modules now have consistent testing framework
- Cleaned up temporary development files
MAJOR IMPROVEMENT: Simplified test discovery logic
- Removed restrictive valid_patterns requirement from testing framework
- Any function starting with 'test_' is now automatically discovered
- Follows standard pytest conventions - no maintenance overhead
- Eliminates need to manually add patterns for new test functions
CLEANED UP: Test function names across all 10 modules
- Removed redundant '_comprehensive' suffix from all test functions
- Updated 40+ test function names to be more concise and readable:
* 00_setup: 6 functions (test_personal_info, test_system_info, etc.)
* 01_tensor: 4 functions (test_tensor_creation, test_tensor_properties, etc.)
* 02_activations: 1 function (test_activations)
* 03_layers: 3 functions (test_matrix_multiplication, test_dense_layer, etc.)
* 04_networks: 4 functions (test_sequential_networks, test_mlp_creation, etc.)
* 05_cnn: 3 functions (test_convolution_operation, test_conv2d_layer, etc.)
* 06_dataloader: 4 functions (test_dataset_interface, test_dataloader, etc.)
* 07_autograd: 6 functions (test_variable_class, test_add_operation, etc.)
* 08_optimizers: 5 functions (test_gradient_descent_step, test_sgd_optimizer, etc.)
* 09_training: 6 functions (test_mse_loss, test_crossentropy_loss, etc.)
* 10_compression: 6 functions (already cleaned up)
VERIFICATION: All tests still pass
- All 10 modules tested successfully with new discovery logic
- Total test count maintained: 47 inline tests across all modules
- No functionality lost, only improved maintainability
RESULT: Much cleaner, more maintainable testing framework following standard conventions
- 00_setup: Fix naming inconsistency (setup_health → setup_score)
- Tests expected 'setup_score' key but implementation returned 'setup_health'
- Updated all references to use consistent 'setup_score' naming
- Result: 37/37 tests now passing
- 05_cnn: Fix flatten function shape expectations
- Comprehensive tests expected (4,) shape but integration tests expected (1,4) shape
- Made comprehensive tests consistent with integration test expectations
- Flatten function now correctly preserves batch dimension for realistic usage
- Result: 39/39 tests now passing
- 08_optimizers: Fix recursion error in test execution
- Direct test call was causing infinite recursion loop
- Removed problematic direct test call, rely on auto-discovery system
- Result: 5/5 tests now passing
All inline tests now pass: 214/214 tests (100% success rate)
- Updated 07_autograd module with auto-discovery testing infrastructure
- Renamed all test functions to follow _comprehensive/_integration pattern
- Updated all function calls to use new names
- Added main section with run_module_tests_auto('Autograd')
- All 6 test functions now working with auto-discovery
- Updated 08_optimizers module with auto-discovery testing infrastructure
- Renamed all test functions to follow _comprehensive/_integration pattern
- Updated all function calls to use new names
- Added main section with run_module_tests_auto('Optimizers')
- All 5 test functions now working with auto-discovery
- Modules 09-13 are currently empty (no development files yet)
- All existing modules (00-08) now use consistent testing architecture
- Testing utilities properly located in tito/tools (not core library)
- Zero-maintenance auto-discovery system working across all modules
- Replaced 3 overlapping documentation files with 1 authoritative source
- Set modules/source/08_optimizers/optimizers_dev.py as reference implementation
- Created comprehensive module-rules.md with complete patterns and examples
- Added living-example approach: use actual working code as template
- Removed redundant files: module-structure-design.md, module-quick-reference.md, testing-design.md
- Updated cursor rules to point to consolidated documentation
- All module development now follows single source of truth
✅ Updated modules to use consistent testing format:
- 08_optimizers: 'Testing X...' → '🔬 Unit Test: X...'
- 07_autograd: 'Testing X...' → '🔬 Unit Test: X...'
- 02_activations: 'Testing X...' → '🔬 Unit Test: X...'
- 03_layers: 'Testing X...' → '🔬 Unit Test: X...'
🎯 Now all modules follow tensor_dev.py format:
- ✅ Consistent '🔬 Unit Test: [Component]...' format
- ✅ Maintains visual consistency across all modules
- ✅ Clear identification of unit test sections
- ✅ Professional and educational presentation
📊 Status: All 9 modules (00-08) now use unified testing terminology
