TestMu AI, previously known as LambdaTest, has announced major enhancements to its Real Device Cloud, aimed at improving the testing of modern applications. The platform now supports Playwright automation across multiple programming languages, including Java, Python, and C#, allowing enterprise teams to integrate testing seamlessly into their existing workflows. This multi-language support addresses the growing adoption of Playwright among engineering teams, enabling them to validate applications on real devices without being limited to JavaScript.

In addition, TestMu AI has introduced Audio Injection and Live Audio Input capabilities for real iOS devices. This feature enables teams to simulate and validate microphone-based interactions, making it possible to automate tests for various scenarios such as KYC voice verification and in-app audio recording. Mudit Singh, Co-Founder and Head of Growth at TestMu AI, highlighted the importance of replicating real-world conditions for testing interactive and voice-enabled applications.

These enhancements not only extend testing coverage but also enable teams to move beyond traditional UI validation, ensuring accurate validation of increasingly complex user experiences at scale.
