max-heal 0.1.2

Playwright wrapper with LLM-powered auto-heal and flaky auto-fix

MaxHeal

Playwright wrapper with LLM-powered auto-heal and flaky auto-fix for Python.

Features

• 🔧 Auto-heal broken selectors at runtime using an LLM (via OpenRouter)
• 🔁 Flaky guard — smart retry decorator for unstable async tests
• 🪶 Zero friction — drop-in wrapper around your existing Playwright page
• ⚡ Selector cache — healed selectors are reused within a session (no duplicate LLM calls)

Python Quick Start (Zero-Setup)

Install via pip:

pip install max-heal

Then, simply configure MaxHeal globally before your tests run (e.g., in a conftest.py or application setup file). MaxHeal will automatically intercept all playwright.sync_api.expect and playwright.async_api.expect calls across your entire framework.

import pytest
from playwright.sync_api import Page
from max_heal import MaxHealConfig, create_maxheal_page

# 1. Global AI Configuration
MAXHEAL_CONFIG = MaxHealConfig(
    api_key="sk-or-your-api-key",
    model="openai/gpt-4o-mini",
    max_retries=3
)

# 2. Wrap the global Playwright page fixture natively
@pytest.fixture
def page(page: Page):
    # This automatically activates the Global AssertPatch for this page
    return create_maxheal_page(page, MAXHEAL_CONFIG)

# 3. Write native tests normally — NO CODE CHANGES REQUIRED!
def test_login(page: Page):
    page.goto("https://example.com/login")
    
    # If the DOM changes and `#btn-signin` breaks, MaxHeal instantly freezes,
    # queries the LLM, injects the new selector, and retries the assert!
    from playwright.sync_api import expect
    expect(page.locator("#btn-signin")).to_be_visible(timeout=5000)
    page.locator("#btn-signin").click()

Advanced AI Context (Allure/Logs)

MaxHeal allows you to inject testing metadata directly into the LLM's brain so it understands what the automation is actually trying to do. Just populate the global_context dictionary.

from max_heal import global_context
import allure

def add_step(step_name):
    global_context["Current Test Step"] = step_name
    allure.step(step_name)

Configuration

Option	Python default	Description
api_key	""	OpenRouter API key
model	openai/gpt-4o-mini	Chat model (any OpenRouter model)
base_url	https://openrouter.ai/...	OpenRouter base URL
max_retries	3	Heal attempts per selector failure
heal_enabled	True	Toggle auto-healing globally
timeout	30.0	HTTP timeout for LLM calls (seconds)

How It Works

Test Action -> Timeout Error / Strict Mode Violation
        │
        ▼
  Snapshot DOM (aria tree + HTML)
        │
        ▼
  Prompt LLM (selector + error + DOM + Context)
        │
        ▼
  Parse healed selector
        │
        ▼
  Retry Native Assertion directly with new selector
        │
        ▼
  Cache result to prevent duplicate LLM calls
