🧪 PAXECT Polyglot Plugin — Test and Quality Validation

This document provides a detailed overview of the testing, coverage, and validation framework for the PAXECT Polyglot Plugin — the deterministic multi-language bridge of the PAXECT ecosystem.

---

1. Overview

The Polyglot Plugin is validated through a comprehensive test suite designed to ensure:

• Deterministic runtime and reproducible transformations
• Stable cross-language bridge behavior (Python, Node.js, Go)
• Cross-platform consistency (Linux, macOS, Windows)
• Full offline operation with no network dependencies

Testing and coverage are performed using:

• pytest — structured functional and integration testing
• coverage.py — detailed code-path and branch coverage reports
• zstandard, hashlib, and subprocess for runtime bridge checks

3. Environment Setup

# Clone repository
git clone https://github.com/<your-org>/paxect-polyglot-plugin.git
cd paxect-polyglot-plugin

# Create and activate virtual environment
python3 -m venv .venv
source .venv/bin/activate

# Install dependencies
python3 -m pip install -r requirements.txt

Optional (for extended coverage):

python3 -m pip install pytest coverage numpy

---

4. Running Tests

Run the entire test suite:

python3 -m pytest -v

Run with coverage:

python3 -m coverage run -m pytest -v
python3 -m coverage report -m

Generate an HTML report:

python3 -m coverage html

---

5. Example pytest.ini

# pytest.ini — PAXECT Polyglot standard configuration
[pytest]
addopts = -ra -q
testpaths = tests
python_files = test_*.py
python_functions = test_*
filterwarnings =
    ignore::DeprecationWarning

---

6. Coverage Script (coverage_run.sh)

#!/usr/bin/env bash
# PAXECT Polyglot — Coverage Runner

set -e
echo "=== PAXECT Polyglot — Coverage Test Run ==="
DATE=$(date -u +"%Y-%m-%d %H:%M:%S UTC")
echo "Started: $DATE"
echo

rm -f .coverage || true
rm -rf htmlcov || true

python3 -m coverage run -m pytest -v --maxfail=1 --disable-warnings
python3 -m coverage report -m
python3 -m coverage html

echo
echo "HTML report generated at: htmlcov/index.html"
echo "=== Test run completed successfully ==="

Make it executable:

chmod +x coverage_run.sh

---

7. Test Metrics (Reference)

Metric	Result
Tests Passed	100 % (11/11)
Coverage	95 % (core bridge)
Framework	pytest + coverage.py
Compatibility	Linux, macOS, Windows
Python	3.9 – 3.12

---

8. CI/CD Integration

GitHub Actions Example

jobs:
  polyglot-tests:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Set up Python
        uses: actions/setup-python@v5
        with:
          python-version: '3.12'
      - name: Run Polyglot Tests
        run: ./coverage_run.sh

GitLab CI Example

polyglot_test:
  image: python:3.12
  script:
    - ./coverage_run.sh
  artifacts:
    when: always
    paths:
      - htmlcov/

9. Quality Principles

• Reproducibility: Identical cross-language results across OSes
• Integrity: Verified data path with CRC32 + SHA-256
• Isolation: No external I/O or network required
• Transparency: Deterministic runtime and inspectable logs
• Stability: Predictable bridge latency under load
