PAXECT Core — Test and Quality Validation

This document provides a detailed overview of the testing, validation, and reproducibility framework for the PAXECT Core Production Plugin — the deterministic container engine powering all PAXECT components.

1. Overview

The PAXECT Core engine is validated through an extensive automated test and verification suite that guarantees:

Deterministic and bit-identical behavior across all supported systems
Cross-platform reproducibility (Linux, macOS, Windows)
Structural integrity and checksum validation at frame and container levels
Stable encode/decode performance under varying workloads
Offline execution — no external dependencies or network calls

Testing and coverage are performed using:

pytest — structured functional and integration testing
coverage.py — detailed code-path and branch coverage reports
zstandard and psutil — runtime performance and compression validation tools

3. Environment Setup

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

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

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

Optional (for extended performance benchmarks):

python3 -m pip install numpy

4. Running Tests

To run the complete test suite with coverage:

./coverage_run.sh

or manually:

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

This validates all container-level operations including:

Header and footer serialization
CRC32 and SHA-256 integrity verification
Multi-channel encode/decode correctness
Streamed stdin/stdout pipeline behavior

5. Test Metrics

Metric	Result (Reference)
Tests Passed	100 % (12 / 12)
Coverage	95 % (core logic)
Framework	pytest + coverage.py
Compatibility	Linux · macOS · Windows
Python	3.9 – 3.12

6. CI/CD Integration

The test framework is fully CI-compatible and ready for enterprise pipelines:

GitHub Actions: Run ./coverage_run.sh or add a make coverage job.
GitLab CI: Add a pytest stage for coverage validation.
Jenkins / Bamboo: Execute coverage runs inside isolated environments.

Artifacts such as .coverage and .pytest_cache/ are automatically ignored via .gitignore.

7. Test Modules

Module	Description
`test_container_encode.py`	Validates header fields, version = 42, and encode logic.
`test_container_decode.py`	Verifies decode integrity, error codes, and fail-safe exit.
`test_crc_integrity.py`	Confirms CRC32 validation per frame.
`test_sha256_footer.py`	Confirms SHA-256 hash matching between encode/decode.
`test_multichannel.py`	Tests 1–8 channel configurations and auto-mode.
`test_stream_io.py`	Validates stdin/stdout streaming behavior and buffering.

8. Quality Principles

PAXECT Core follows the same enterprise engineering standards across the ecosystem:

Determinism: Identical container output per run and per OS.
Integrity: Enforced CRC + SHA validation on every frame.
Isolation: No network access or side-effects.
Transparency: Readable and inspectable binary structure.
Stability: Predictable performance under multi-threaded load.

9. Coverage Script (`coverage_run.sh`)

This script provides a unified coverage execution routine for local and CI environments.

#!/usr/bin/env bash
# PAXECT Core — Coverage Runner
# Executes all tests with full coverage reporting

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

# Clean previous reports
rm -f .coverage || true
rm -rf htmlcov || true

# Run coverage suite
python3 -m coverage run -m pytest -v --maxfail=1 --disable-warnings
python3 -m coverage report -m

# Optional: generate HTML report
python3 -m coverage html
echo
echo "HTML report generated at: htmlcov/index.html"
echo "=== Test run completed successfully ==="

Make the script executable:

chmod +x coverage_run.sh
