## Diagnostic Framework
### Common Pytest Issues & Solutions
#### 1. Import Path Problems
```python
# Common Issue: ModuleNotFoundError
# Solution: PYTHONPATH configuration
def fix_import_paths():
"""Ensure PYTHONPATH is correctly set for test execution."""
import os
import sys
# Add project root to path
project_root = os.path.dirname(os.path.abspath(__file__))
if project_root not in sys.path:
sys.path.insert(0, project_root)
```
#### 2. Cache Corruption Issues
```python
# Common Issue: Pytest cache corruption
# Solution: Cache cleanup and optimization
def optimize_pytest_cache():
"""Clean and optimize pytest cache for reliable execution."""
cache_dirs = ['.pytest_cache', '__pycache__']
# Implementation for cache cleanup
```
#### 3. Test Discovery Problems
```python
# Common Issue: Tests not discovered or run
# Solution: Improved test discovery configuration
def optimize_test_discovery():
"""Optimize pytest test discovery patterns."""
pytest_config = {
'testpaths': ['tests'],
'python_files': ['test_*.py', '*_test.py'],
'python_classes': ['Test*'],
'python_functions': ['test_*']
}
```
### Performance Optimization Strategies
#### 1. Smart Test Selection
- **Changed File Detection**: Run tests only for modified code
- **Dependency Analysis**: Include tests for dependent modules
- **Test Impact Analysis**: Prioritize high-impact test execution
- **Incremental Testing**: Cache results for unchanged code
#### 2. Parallel Execution Optimization
- **Worker Process Management**: Optimal number of parallel workers
- **Test Distribution**: Smart distribution across workers
- **Resource Management**: Memory and CPU optimization
- **Lock Management**: Prevent resource conflicts
#### 3. Cache Optimization
- **Result Caching**: Cache test results for unchanged code
- **Dependency Caching**: Cache test dependencies
- **Import Caching**: Optimize module import caching
- **Data Caching**: Cache test data and fixtures
## TDD8 Integration Patterns
### Red Phase Optimization
```bash
# Fast failure detection
make test-quick # Run fastest tests first
make test-changed # Run tests for changed files only
make test-arch # Run architectural tests quickly
```
### Green Phase Optimization
```bash
# Comprehensive validation
make test # Full test suite
make test-coverage # With coverage analysis
make test-integration # Integration tests
```
### Continuous Feedback
```bash
# Watch mode for continuous testing
make test-watch # Auto-run tests on file changes
make test-tdd # TDD-optimized test execution
```
## Optimization Strategies
### 1. Test Execution Efficiency
#### Fast Feedback Loops
- **Subset Testing**: Run minimal tests for quick feedback
- **Parallel Execution**: Utilize multiple cores effectively
- **Smart Caching**: Cache test results and dependencies
- **Incremental Execution**: Run only necessary tests
#### Reliability Improvements
- **Robust Configuration**: Eliminate configuration-related failures
- **Error Recovery**: Automatic recovery from common issues
- **Clear Diagnostics**: Meaningful error messages and debugging info
- **Health Checks**: Pre-execution environment validation
### 2. TDD8 Workflow Integration
#### Red-Green Cycle Optimization
- **Fast Red**: Quick test execution to confirm failure
- **Efficient Green**: Targeted test execution for implementation
- **Smart Refactor**: Test execution during refactoring phases
- **Continuous Validation**: Background test execution
#### Intelligent Test Selection
```python
class SmartTestSelector:
def select_tests_for_change(self, changed_files: List[str]) -> List[str]:
"""Select relevant tests based on changed files."""
def prioritize_tests(self, test_files: List[str]) -> List[str]:
"""Prioritize tests by execution time and importance."""
def filter_by_coverage(self, tests: List[str], coverage_threshold: float) -> List[str]:
"""Filter tests based on code coverage impact."""
```
### 3. Infrastructure Optimization
#### Pytest Configuration Enhancement
```ini
# Enhanced pytest.ini configuration
[tool:pytest]
minversion = 6.0
addopts =
--strict-markers
--strict-config
--disable-warnings
--tb=short
--maxfail=5
--timeout=300
-ra
testpaths = tests
python_files = test_*.py
python_classes = Test*
python_functions = test_*
markers =
slow: marks tests as slow
integration: marks tests as integration tests
unit: marks tests as unit tests
smoke: marks tests as smoke tests
```
#### Make Target Optimization
```makefile
# Optimized test targets
test-fast:
@echo "🏃‍♂️ Running fast tests..."
PYTHONPATH=. python -m pytest tests/ -m "not slow" --maxfail=3 -x
test-changed:
@echo "🔄 Running tests for changed files..."
PYTHONPATH=. python -m pytest $(shell git diff --name-only HEAD~1 | grep test_ | tr '\n' ' ')
test-smart:
@echo "🧠 Running smart test selection..."
PYTHONPATH=. python tools/smart_test_selector.py | xargs python -m pytest
```
## Agent Integration Guidelines
### 1. Test Execution Patterns for Agents
#### Preferred Test Commands
```bash
# Primary test execution (most reliable)
make test
# Fast feedback for TDD
make test-quick
# Changed files only
make test-changed
# Specific test file
PYTHONPATH=. python -m pytest tests/specific_test.py -v
```
#### Error Handling Patterns
```python
# Robust test execution with error handling
def execute_tests_safely(test_target: str = "test") -> TestResult:
"""Execute tests with proper error handling and recovery."""
try:
# Clear cache if needed
clear_pytest_cache()
# Set proper environment
setup_test_environment()
# Execute tests
result = run_test_command(f"make {test_target}")
return result
except PytestError as e:
# Handle specific pytest errors
return handle_pytest_error(e)
except Exception as e:
# Handle general errors
return handle_general_error(e)
```
### 2. TDD8 Workflow Integration
#### Red Phase Agent Pattern
```python
def execute_red_phase_tests(test_file: str) -> bool:
"""Execute tests for TDD red phase - expect failures."""
result = execute_tests_safely("test-quick")
if result.has_failures:
logger.info("✅ Red phase successful - tests failing as expected")
return True
else:
logger.warning("⚠️ Red phase issue - tests not failing")
return False
```
#### Green Phase Agent Pattern
```python
def execute_green_phase_tests() -> bool:
"""Execute tests for TDD green phase - expect success."""
result = execute_tests_safely("test")
if result.all_passed:
logger.info("✅ Green phase successful - all tests passing")
return True
else:
logger.error("❌ Green phase failed - implementation needs work")
return False
```
## Monitoring & Metrics
