# lambdatest-sdk-utils — SDK utils

License: permissive · Maintenance: active · Downloads: 308.8K/mo

## What it is and what it does

This package provides Python utilities to integrate with TestMu AI (formerly LambdaTest), a cloud-based testing platform offering access to thousands of real browsers and devices. It enables developers to run Selenium, Appium, Playwright, and other test automation frameworks against real browser environments hosted in the cloud, rather than managing local test infrastructure. The SDK handles authentication via environment variables and provides utilities like SmartUISnapshot for visual regression testing.

The package is designed for teams running cross-browser and cross-device test suites at scale. It abstracts the complexity of connecting to TestMu AI's cloud infrastructure, allowing test scripts to execute remotely while maintaining compatibility with standard test frameworks. Setup requires Python 3.6+, a TestMu AI account, and credentials stored as environment variables.

Use it for:

- Run Selenium tests across hundreds of real browser and OS combinations without maintaining local test infrastructure.
- Capture visual regression snapshots during test execution to detect unintended UI changes.
- Test locally hosted applications by configuring the TestMu AI tunnel within test capabilities.
- Execute Playwright-based tests on real devices in the cloud for comprehensive cross-browser coverage.
- Integrate automated testing into CI/CD pipelines using cloud-hosted test infrastructure.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides Python SDK utilities for integrating with TestMu AI (formerly LambdaTest) to run automated tests across real browsers and devices in the cloud.

Yes, if you need cloud-based cross-browser testing. The package has low install friction, active maintenance, permissive MIT licensing, and no known vulnerabilities. It integrates cleanly with standard test frameworks (Selenium, Playwright, Appium) and abstracts away infrastructure management. Install only if you have or plan to obtain a TestMu AI account; the SDK alone is a client library with no standalone value.

## Install

pip install lambdatest-sdk-utils
uv add lambdatest-sdk-utils
poetry add lambdatest-sdk-utils

## Installing lambdatest-sdk-utils

Before you install: Low install friction with a single pure-Python wheel dependency on requests. Actively maintained with recent releases; last commit 2026-05-17 and latest release 2025-11-26 indicate ongoing support.

License in practice: MIT license permits commercial and private use with minimal restrictions, making it straightforward to adopt in most projects.

Quickstart:

pip install lambdatest-sdk-utils

from lambdatest_sdk import SmartUISnapshot

# Capture a SmartUI snapshot
SmartUISnapshot.capture(driver, "my-snapshot")

Requires Python 3.6 or higher; TestMu AI account credentials (username and access key) must be set as environment variables LT_USERNAME and LT_ACCESS_KEY.

Verify before relying:

- Whether SmartUISnapshot and other SDK classes are actually exported from the lambdatest_sdk module as shown in the description.
- Full scope of available SDK utilities beyond SmartUISnapshot—the package summary is minimal.
- Support for Playwright integration mentioned in description—exact API and availability unclear.
