Discover how to implement sub-second integration tests for React Native apps with Bluetooth device integration in this React Native EU 2021 conference talk. Learn about the "mock recording" technique for fast and robust testing, explore an open-source tool developed in collaboration with SOUNDBOKS, and see a live demonstration of its capabilities. Gain insights into the methodology, tool usage, and the benefits of this approach for app development. Understand the architecture behind recording Bluetooth traffic, writing app tests using Jest, and debugging recordings. Explore the balance between end-to-end testing and unit testing, and learn how to handle various challenges in Bluetooth app testing.
