# TestMu AI (Formerly LambdaTest) Skills

A collection of installable AI-agent skills that teach coding assistants like Claude Code, Copilot, Cursor, and Gemini CLI to write and run test automation code against TestMu AI's cloud of real devices and browsers.

TestMu AI (Formerly LambdaTest) Skills packages test automation agent skills for major frameworks across more than 15 languages, so AI coding assistants can write test automation code for Selenium, Appium, Playwright, and other frameworks. Skills install with a package-manager command after cloning the repository, and credentials are set through environment variables tied to a TestMu AI account.

Once installed, a developer can ask their AI assistant in plain language to write and run tests, for example generating Playwright tests for a login page and running them on the TestMu AI cloud across multiple browsers, or creating JUnit 5 tests with a mocking library and a continuous-integration pipeline, then view results on the TestMu AI dashboard. A tunnel tool supports testing locally hosted applications from the cloud.

A companion tool is a terminal tool for testing AI agents a user owns: it reads the agent's own codebase, generates test scenarios, invokes the agent for real, and grades the resulting evidence.
