Configuration Support:¶

pyproject.toml updated with optional dependencies
CLI entry point added: provide-testkit quality
Gitignore updated to exclude quality reports

🎯 Usage Examples That Work¶

1. Using Quality Decorators:¶

from provide.testkit.quality import quality_check

@quality_check(performance={'max_memory_mb': 50.0})
def my_test_function():
    # This function's performance will be monitored
    return expensive_computation()

2. Using pytest Fixtures:¶

def test_coverage(coverage_tracker):
    result = coverage_tracker.analyze(Path("./src"))
    assert result["passed"]
    assert result["coverage_percentage"] >= 80.0

3. Using Quality Runner:¶

from provide.testkit.quality.runner import QualityRunner

runner = QualityRunner()
results = runner.run_tools(Path("./src"), ["coverage", "security"])

4. Using CLI (when dependencies installed):¶

provide-testkit quality analyze ./src --tool coverage --tool security

📈 Metrics Collected¶

The framework collects rich metrics including:

Coverage: Percentage, lines covered/missing, file-level breakdowns
Security: Issue counts by severity, specific vulnerability details
Complexity: Average/max complexity, function-level analysis, grade distributions
Documentation: Docstring coverage, missing documentation locations
Performance: Memory usage, execution time, CPU profiling data

🔧 Technical Architecture¶

Protocol-based design allows easy extension
Dataclass-based results provide type safety
Lazy imports prevent performance overhead
Exception handling ensures graceful degradation
Artifact management provides organized output storage
Multiple output formats support different use cases

✅ Quality Gates Proven Working¶

The framework successfully: - ✅ Enforces minimum coverage thresholds - ✅ Blocks on security vulnerabilities - ✅ Validates complexity requirements - ✅ Checks documentation coverage - ✅ Monitors performance constraints - ✅ Provides clear pass/fail feedback - ✅ Generates actionable reports

🎉 Conclusion¶

The provide-testkit quality module is FULLY IMPLEMENTED and PROVEN WORKING.

The demonstration scripts show: 1. Complete functionality across all 5 quality tools 2. Rich, information-dense reports in multiple formats 3. Working quality decorators with real enforcement 4. Comprehensive artifact management with organized storage 5. Production-ready architecture with proper error handling

The quality-reports/ directory contains actual generated reports proving the implementation works end-to-end, generating the exact "information-rich structure" requested.
