TestMu AI announces major enhancements to its Real Device Cloud, expanding Playwright automation across Java, Python, and C#, and introducing Audio Injection and Live Audio Input for testing on real iOS devices.

The new capabilities address multimodal testing by validating voice, audio, and real-time interactions on actual hardware, not just visual UI.

TestMu AI brands itself as the world’s first Agentic AI-native Quality Engineering platform, designed to automate and scale testing using AI-driven intelligence across modern development workflows.

Audio Injection enables using pre-recorded audio, while Live Audio Input streams real-time microphone input to test voice-driven experiences such as KYC voice verification, speech-to-text, in-app audio recording, and conferencing.

The updates strengthen TestMu AI’s Real Device Cloud by enabling scalable, automated testing of complex, real-world user experiences on physical devices.

The update allows running Playwright tests on real devices in multiple programming languages, enabling broader integration of Playwright into varied language ecosystems beyond JavaScript.
