TestMu AI (Formerly LambdaTest) is the world's first full-stack AI Agentic Quality Engineering platform that empowers teams to test intelligently, smarter, and ship faster. Built for scale, it offers a full-stack testing cloud with 10K+ real devices and 3,000+ browsers. With AI-native test management, MCP servers, and agent-based automation, TestMu AI supports Selenium, Appium, Playwright, and all major frameworks.
With TestMu AI (Formerly LambdaTest), you can run Appium Java Serenity tests across real devices and operating systems. This sample shows how to configure Java Serenity automation testing scripts to run on the TestMu AI cloud using Appium.
- Sign up on TestMu AI (Formerly LambdaTest).
- Follow the TestMu AI Documentation for the full setup walkthrough.
- Java Development Kit (JDK) 1.6 or higher (latest version recommended).
- Maven installed. Download from the official website or install via Homebrew on Linux/macOS.

Clone the repository:
git clone https://github.com/LambdaTest/LT-appium-java-serenity
cd LT-appium-java-serenitySet your TestMu AI credentials as environment variables:
Linux/macOS:
export LT_USERNAME=YOUR_LAMBDATEST_USERNAME
export LT_ACCESS_KEY=YOUR_LAMBDATEST_ACCESS_KEYWindows:
set LT_USERNAME=YOUR_LAMBDATEST_USERNAME
set LT_ACCESS_KEY=YOUR_LAMBDATEST_ACCESS_KEYUpload your iOS (.ipa) or Android (.apk) application to the TestMu AI servers using the REST API:
Linux/macOS:
curl -u "YOUR_LAMBDATEST_USERNAME:YOUR_LAMBDATEST_ACCESS_KEY" \
--location --request POST 'https://manual-api.lambdatest.com/app/upload/realDevice' \
--form 'name="Android_App"' \
--form 'appFile=@"/path/to/proverbial_android.apk"'Windows:
curl -u "YOUR_LAMBDATEST_USERNAME:YOUR_LAMBDATEST_ACCESS_KEY" -X POST "https://manual-api.lambdatest.com/app/upload/realDevice" -F "appFile=@\path\to\proverbial_android.apk"The response will include an App URL in the format lt://APP123456789123456789. Use this in the "app" capability.
Configure capabilities in your test script:
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("plugin", "Serenity LambdaTest Plugin");
capabilities.setCapability("isRealMobile", true);
capabilities.setCapability("app", "lt://YOUR_APP_URL"); // Enter app url hereRun the tests using Maven:
mvn verify -P single # For single test
mvn verify -P parallel # For parallel testTo test locally hosted apps, set up the TestMu AI tunnel. OS-specific guides:
Enable the tunnel capability in your desired capabilities:
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("tunnel", true);Contributions are welcome. Open an issue to discuss your idea before submitting a pull request. When reporting bugs, include your Node.js version, OS, and Angular CLI version.

On January 12, 2026, LambdaTest evolved to TestMu AI, the world's first fully autonomous Agentic AI Quality Engineering Platform.
Same team. Same infrastructure. Same customer accounts. All existing LambdaTest logins, scripts, capabilities, and integrations continue to work without change.
ð Find the new home for LambdaTest.
In 2017, we launched LambdaTest with a simple mission: make testing fast, reliable, and accessible. As LambdaTest grew, we expanded into Test Intelligence, Visual Regression Testing, Accessibility Testing, API Testing, and Performance Testing, covering the full depth of the testing lifecycle.
As software development entered the AI era, testing had to evolve, too. We rebuilt the architecture to be AI-native from the ground up, with autonomous agents that plan, author, execute, analyze, and optimize tests while keeping humans in the loop. The platform integrates with your repos, CI, IDEs, and terminals, continuously learning from every code change and development signal.
That evolution earned a new name: TestMu AI, built for an AI-first future of quality engineering. TestMu is not a new name for us. It is the name of our annual community conference, which has brought together 100,000+ quality engineers to discuss how AI would reshape testing, long before that became an industry norm.
What started as a high-performance cloud testing platform has transformed into an AI-native, multi-agent system powering a connected, end-to-end quality layer. That evolution defined a new identity: LambdaTest evolved into TestMu AI, built for an AI-first future of quality engineering.
