CI/CD and Testing Infrastructure - Summary

Overview

Comprehensive CI/CD pipeline and testing infrastructure added to ensure code quality and compatibility across Python 3.10-3.13.

What Was Added

1. GitHub Actions CI Pipeline (.github/workflows/ci.yml)

4 parallel jobs:

Lint Job

  • Black - Code formatting check
  • Ruff - Fast Python linter
  • mypy - Static type checking
  • Runs on Python 3.12

Test Job

  • Matrix testing on Python 3.10, 3.11, 3.12, 3.13
  • pytest with 32 unit tests
  • Coverage reporting (46% coverage)
  • Codecov integration for coverage tracking

Package Job

  • Build verification with python -m build
  • Installation test from wheel
  • CLI verification (search-audit --help)

Security Job

  • Safety - Dependency vulnerability scanning
  • Bandit - Security issue detection

2. Comprehensive Test Suite

32 unit tests across 6 test modules:

Module Tests Coverage Description
test_types.py 4 100% Core type validation
test_config.py 3 39% Configuration loading
test_judge.py 8 100% (rubric) LLM judge & rubric
test_extractors.py 6 N/A Extractor configs
test_report.py 8 97% Report generation
test_cli.py 5 40% CLI interface

Overall coverage: 46%

3. Test Configuration

pyproject.toml updates:

[tool.pytest.ini_options]
testpaths = ["tests"]
asyncio_mode = "auto"
addopts = ["-v", "--strict-markers", "--strict-config", "--tb=short"]
markers = [
    "unit: Unit tests",
    "integration: Integration tests",
    "slow: Slow tests that may take a while",
]

Added test dependencies:

  • pytest>=7.0.0
  • pytest-asyncio>=0.21.0
  • pytest-cov>=4.0.0
  • pytest-mock>=3.12.0
  • types-pyyaml>=6.0.0
  • build>=1.0.0

4. Pre-commit Hooks (.pre-commit-config.yaml)

Updated to latest versions:

  • pre-commit-hooks v4.5.0 - Trailing whitespace, EOF fixer, YAML/JSON/TOML validation
  • Black 24.1.1 - Code formatting (100 char line length)
  • Ruff v0.1.15 - Fast linting with auto-fix
  • mypy v1.8.0 - Type checking

5. Makefile

Common development tasks:

make help           # Show all commands
make install        # Install package
make install-dev    # Install with dev dependencies
make test           # Run all tests
make test-cov       # Run tests with coverage
make test-unit      # Run only unit tests
make lint           # Run linters
make format         # Format code
make typecheck      # Run mypy
make pre-commit     # Run pre-commit hooks
make clean          # Clean build artifacts
make build          # Build package
make ci             # Run all CI checks locally

6. Test Fixtures (tests/conftest.py)

Shared fixtures for all tests:

  • project_root - Project directory
  • configs_dir - Config directory
  • data_dir - Data directory
  • mock_env_vars - Auto-mocked environment variables
  • sample_config_dict - Sample configuration

7. Documentation

New files:

  • TESTING.md (350+ lines) - Comprehensive testing guide
    • How to run tests
    • Test organization
    • Writing tests
    • CI/CD overview
    • Debugging tips
    • Best practices

Updated files:

  • README.md - Added testing section with coverage stats
  • requirements-dev.txt - Added new test dependencies

Test Coverage Details

High Coverage Modules (>90%)

Module Coverage Lines Miss
core/types.py 100% 87 0
report/generator.py 97% 148 4
judge/rubric.py 100% 11 0

Lower Coverage Modules (need integration tests)

Module Coverage Reason
mcp/client.py 26% Requires browser automation
extractors/* 17-21% Requires DOM interaction
core/orchestrator.py 22% End-to-end flow testing
core/policies.py 0% Not yet tested

Python Version Support

✅ Tested on:

  • Python 3.10
  • Python 3.11
  • Python 3.12
  • Python 3.13

All classifiers updated in pyproject.toml.

CI Workflow Features

Fast Feedback

  • Lint job completes in ~1-2 minutes
  • Test jobs run in parallel
  • Cached pip dependencies for speed

Quality Gates

  • Code must pass Black formatting
  • Code must pass Ruff linting
  • Type checking with mypy (warnings allowed initially)
  • All tests must pass on all Python versions

Coverage Tracking

  • Coverage report uploaded to Codecov (Python 3.12 only)
  • HTML coverage report generated as artifact
  • Terminal coverage summary in job output

Running Tests Locally

Quick Start

# Install dependencies
make install-dev

# Run tests
make test

# Run with coverage
make test-cov

# View coverage report
open htmlcov/index.html

Running Specific Tests

# Single test file
pytest tests/test_types.py -v

# Single test function
pytest tests/test_judge.py::test_judge_schema -v

# Only unit tests
pytest -m unit

# With debug output
pytest -vv -s

Pre-commit

# Install hooks
pre-commit install

# Run manually
make pre-commit

Bug Fixes

Fixed NameError in extractors/modals.py:

  • Added missing Optional import from typing

Benefits

  2. Cross-version Testing: Ensure compatibility with Python 3.10-3.13
  3. Developer Experience: Fast feedback with local CI simulation
  4. Documentation: Clear testing guide for contributors
  5. Code Coverage: Track and improve test coverage over time
  6. Security: Automated vulnerability scanning

Future Improvements

  • Increase coverage to 80%+
  • Add integration tests for browser automation
  • Add end-to-end tests with mocked LLM
  • Add property-based testing with Hypothesis
  • Add performance benchmarks
  • Add mutation testing with mutmut
