TestMu AI (Formerly LambdaTest) is an Agentic AI Quality Engineering platform that assures AI deployments across the enterprise and the real world. It runs agentic testing for web and mobile apps on 3,000+ browsers and 50,000+ real devices, and for chat, voice, IVR, video, and image agents. For test creation, KaneAI turns natural language prompts, PRDs and tickets into end-to-end tests that it plans, authors, runs and keeps up to date as the app changes. Kane CLI brings the same agent to the terminal, so developers, coding agents and CI pipelines can confirm that a browser flow really works. For teams shipping AI products, Agent Testing builds 60 to 100+ scenarios from PRDs, docs or Jira and measures chatbots, voice assistants and phone agents on hallucination, bias, tone and compliance, then gives a Green, Yellow or Red go-live verdict. Agent Assurance checks agents that take actions, such as coding and workflow agents, by grading the files, artifacts and tool calls they actually produced, and reports Pass, Fail or Unable to Verify. On the infrastructure side, Selenium, Playwright, Cypress and Appium suites run in parallel on the Automation Cloud, HyperExecute runs them up to 70% faster, App Automation supports Appium, Espresso and XCUITest on physical iOS and Android hardware, and Browser Cloud provides browsers built for AI agents. Performance Testing adds protocol-level JMeter load tests. SmartUI compares screenshots to flag visual regressions, the Accessibility Testing Agent audits apps against WCAG, ADA and EAA with TalkBack and VoiceOver on real devices, Test Manager keeps manual and automated cases together, and Test Insights spots flaky tests and explains failures with AI root cause analysis. The TestMu AI MCP Server lets AI clients pull test data. TestMu AI plugs into 120+ tools, from CI/CD servers to issue trackers and team chat, and is used by 3M+ users at 18,000+ enterprises, including Microsoft, OpenAI and Nvidia.
