WebTestpilot

WebTestPilot is an LLM-driven automated web testing framework for end-to-end browser testing.

This directory contains the core source code of WebTestPilot for development and maintenance.

• pytest-webtestpilot: A pytest plugin that integrates WebTestPilot with pytest。

Installation

If you want to use WebTestPilot in your own projects, install it from PyPI:

pip install webtestpilot

WebTestPilot also provides an official pytest plugin for running test cases via pytest.

pip install pytest-webtestpilot

Below is a minimal working example demonstrating how to use WebTestPilot directly on top of Playwright.

from pathlib import Path
from playwright.sync_api import sync_playwright
from webtestpilot import WebTestPilot, Config, Session, Step

# WebTestPilot is built on top of Playwright
with sync_playwright() as p:
    # Users can:
    # 1. Connect to an existing managed or remote browser
    # 2. Enable tracing, video, or screenshots at the browser context level
    # 3. Reuse an authenticated browser session
    # ...
    browser = p.chromium.launch()
    context = browser.new_context()
    page = context.new_page()

    page.goto("https://example.com")

    # Load WebTestPilot configuration
    config = Config.load(Path("./src/config.yaml"))

    # Create a test session bound to the Playwright page
    session = Session(page=page, config=config)

    # Define test steps in natural language
    steps = [
        Step(
            action="Click the login button",
            expectation="The dashboard page is displayed",
        ),
        Step(
            action="Click the profile icon",
            expectation="The user profile menu appears",
        ),
    ]

    # Run the test steps
    WebTestPilot.run(
        session=session,
        steps=steps,
        assertion=False,  # enable to verify expectations
    )

Development

This section is only required if you are developing or modifying WebTestPilot itself.

Prerequisites

Before starting, make sure you have:

• uv package manager

  We use uv to manage Python dependencies and run commands in a clean, reproducible environment.

  Installation guide: https://docs.astral.sh/uv/getting-started/installation/

Setup

1. Clone the repository.

2. Set Up the Python Environment.

   cd ./webtestpilot
   # Installs all dependencies
   uv sync
   # Prepares code used for model interaction and reasoning.
   uv run baml-cli generate --from ./webtestpilot/baml_src
   

3. Configure Environment Variables.

   We use a .env file to store configuration values and secrets (such as API keys).

   Create your own copy:

   cp .env.example .env
   

   Then open .env and edit the following fields:

   # URL of the GUI grounding model (OpenAI-compatible API)
   GUI_GROUNDING_MODEL_BASE_URL="http://localhost:8000/v1"
   
   # Name of the GUI grounding model (HuggingFace format)
   GUI_GROUNDING_MODEL_NAME="inclusionAI/UI-Venus-Ground-7B"
   
   # URL for OpenAI-compatible LLM API
   OPENAI_BASE_URL="https://api.key77qiqi.com/v1"
   
   # Your API key (ask from the course staff)
   OPENAI_API_KEY=""
