turboplex 0.2.3

High Performance Test Engine - Rust + Python

TurboPlex (tpx) — The Test Orchestration Engine for the AI Era

English | Español

Why TurboPlex?

4x faster than Pytest for test execution. The orchestration engine built for the AI era.

Value Proposition

Feature	Description
⚡ 4x Speed	Parallel execution with smart caching (12s → 3s)
🦀 Rust Core	Static analysis and memory management with minimal overhead
🤖 M2M Protocol	Generates .tplex_report.json with AI-actionable errors
👀 Watch Mode	Auto-reload when you save .py files

Installation

# Install from PyPI
pip install turboplex

# Verify the installation
tpx --help

# Clone the repository (dev)
cd turboplex

# Install in development mode
pip install -e .

# Verify the installation
tpx --help

Quick Start

Basic Execution

# Single test
tpx --path tests/test_simple.py

# Multiple directories
tpx --path tests/ --path tests/integration/

# Auto-discover tests
tpx

Watch Mode (TDD Development)

# Run and watch changes in real time
tpx --watch --path tests/

Pytest Compatibility Mode (--compat)

Use this when your suite relies on complex pytest fixtures (conftest.py, client, db, etc.).

tpx --compat --path tests/

MCP Server (IDE Integration)

tpx mcp

Tools exposed over MCP:

• ping
• turboplex_version
• discover(paths=None, compat=False)
• run(selection, compat=False, max_workers=None)
• get_report(path=None)

Integration with AI Agents

# INSTRUCTION FOR YOUR AI AGENT:
# If you detect a .tplex_report.json file in the project,
# read it immediately and propose an automatic fix.

# The file contains:
# - Exact error
# - Failure line
# - Code context (5 lines before and after)

Per-Test Comparison

Metric	pytest	tpx
Time per test	~6s	~1.5s
Caching	No	Yes (SHA-256)
M2M Report	No	Yes (.tplex_report.json)

Configuration

turbo_config.toml File

[execution]
max_workers = 8
default_timeout_ms = 30000
cache_enabled = true

[python]
enabled = true
interpreter = "python"
module = "turboplex_py"
test_paths = ["tests"]
project_path = "."

Cache

The cache is stored in .turboplex_cache/ and is automatically invalidated when test files change (SHA-256 hash) or when the runtime fingerprint changes (Python version, dependency lock hash, PYTHONPATH, execution flags).

Files Excluded from the Repository (.gitignore)

This project ignores generated files and local configuration to keep the repository lightweight, reproducible, and free of sensitive data.

• Build artifacts and caches (e.g., target/, **/target/, .cache/)
• Temporary files and logs (*.tmp, *.log, *.swp)
• Local IDE/OS configuration (e.g., .vscode/, .idea/, Thumbs.db, .DS_Store)
• Python local environments and metadata (e.g., .venv/, __pycache__/, *.egg-info/)
• Environment files with secrets or local configuration (.env, .env.*)
• Web tooling dependencies and outputs if applicable (node_modules/, dist/, build/)
• TurboPlex-generated caches and reports (.turboplex_cache/, .tplex_report.json)
