- Move testing utilities from tinytorch/utils/testing.py to tito/tools/testing.py - Update all module imports to use tito.tools.testing - Remove testing utilities from core TinyTorch package - Testing utilities are development tools, not part of the ML library - Maintains clean separation between library code and development toolchain - All tests continue to work correctly with improved architecture

# TinyTorch Shared Testing Pattern
|
|
|
|
## 🎯 Problem Solved
|
|
|
|
Previously, each module had inconsistent test summaries and duplicated formatting code. Now all modules use **shared testing utilities** for:
|
|
|
|
✅ **Perfect Consistency** - All modules have identical output format
|
|
✅ **Zero Code Duplication** - Testing utilities are shared across all modules
|
|
✅ **Easy Maintenance** - Changes only need to be made in one place
|
|
✅ **Scalable** - Works for any number of modules and tests
|
|
|
|
## 📋 Usage Pattern
|
|
|
|
### 1. Import the Shared Utilities
|
|
|
|
```python
|
|
from tinytorch.utils.testing import create_test_runner
|
|
```
|
|
|
|
### 2. Write Your Test Functions
|
|
|
|
```python
|
|
def test_feature_a():
|
|
"""Test feature A functionality."""
|
|
# Your test code here
|
|
assert something_works(), "Feature A should work"
|
|
print("✅ Feature A tests passed!")
|
|
|
|
def test_feature_b():
|
|
"""Test feature B functionality."""
|
|
# Your test code here
|
|
assert something_else_works(), "Feature B should work"
|
|
print("✅ Feature B tests passed!")
|
|
```
|
|
|
|
### 3. Register and Run Tests
|
|
|
|
```python
|
|
if __name__ == "__main__":
|
|
# Create test runner for this module
|
|
test_runner = create_test_runner("YourModule")
|
|
|
|
# Register all tests
|
|
test_runner.register_test("Feature A", test_feature_a)
|
|
test_runner.register_test("Feature B", test_feature_b)
|
|
|
|
# Run all tests with consistent output
|
|
success = test_runner.run_all_tests()
|
|
```
|
|
|
|
## 🎭 Standard Output Format
|
|
|
|
Every module produces **identical output**:
|
|
|
|
```
|
|
🔬 Running YourModule Module Tests...
|
|
==================================================
|
|
🧪 Testing Feature A... ✅ PASSED
|
|
🧪 Testing Feature B... ✅ PASSED
|
|
|
|
============================================================
|
|
🎯 YOURMODULE MODULE TESTING COMPLETE
|
|
============================================================
|
|
🎉 CONGRATULATIONS! All tests passed!
|
|
|
|
✅ YourModule Module Status: 2/2 tests passed (100%)
|
|
|
|
📊 Detailed Results:
|
|
Feature A: ✅ PASSED
|
|
Feature B: ✅ PASSED
|
|
|
|
📈 Progress: YourModule Module ✓ COMPLETE
|
|
|
|
🚀 Ready for the next module!
|
|
```
|
|
|
|
## 🏗️ Architecture
|
|
|
|
### Shared Utilities Location
|
|
- **Main utilities**: `tinytorch/utils/testing.py`
|
|
- **Import from**: `from tinytorch.utils.testing import create_test_runner`
|
|
|
|
### ModuleTestRunner Class
|
|
The core class that provides:
|
|
- `register_test(name, function)` - Register test functions
|
|
- `run_all_tests()` - Execute all tests with consistent output
|
|
- Error handling and detailed reporting
|
|
|
|
## 📈 Migration Guide
|
|
|
|
To migrate an existing module:
|
|
|
|
### Before (Inconsistent)
|
|
```python
|
|
# Old way - inconsistent format
|
|
def test_something():
|
|
# test code
|
|
pass
|
|
|
|
# Manual summary - different across modules
|
|
print("Some tests passed!")
|
|
```
|
|
|
|
### After (Consistent)
|
|
```python
|
|
# New way - consistent format
|
|
from tinytorch.utils.testing import create_test_runner
|
|
|
|
def test_something():
|
|
# test code
|
|
print("✅ Something tests passed!")
|
|
|
|
if __name__ == "__main__":
|
|
test_runner = create_test_runner("ModuleName")
|
|
test_runner.register_test("Something", test_something)
|
|
success = test_runner.run_all_tests()
|
|
```
|
|
|
|
## ✅ Benefits Achieved
|
|
|
|
1. **Consistency**: All modules have identical testing output
|
|
2. **No Duplication**: Testing utilities are shared across modules
|
|
3. **Easy Maintenance**: Changes to format only need to be made in one place
|
|
4. **Scalable**: Works for any number of tests and modules
|
|
5. **Professional**: Clean, standardized output suitable for educational use
|
|
6. **Error Handling**: Detailed error reporting for failed tests
|
|
|
|
## 🚀 Implementation Status
|
|
|
|
- **✅ Shared utilities created**: `tinytorch/utils/testing.py`
|
|
- **✅ Documentation complete**: Usage patterns and examples
|
|
- **✅ Testing verified**: Confirmed working with example modules
|
|
- **⏳ Migration pending**: Apply pattern to all existing modules
|
|
|
|
## 🔧 Next Steps
|
|
|
|
1. **Apply to all modules**: Migrate existing modules to use shared pattern
|
|
2. **Test thoroughly**: Ensure all modules work with new pattern
|
|
3. **Update documentation**: Module-specific docs reference shared pattern
|
|
4. **Commit changes**: Save the improved testing infrastructure
|
|
|
|
This shared testing pattern eliminates code duplication while ensuring perfect consistency across all TinyTorch modules! |
