LambdaTest has announced an upgraded version of its Tunnel binary, first introduced in 2018, aimed at enhancing cross-browser testing for locally hosted web applications. The new version, available from November 2020, features a revamped user interface, improved security protocols like Secure Shell and Web Socket, and added functionalities such as MITM mode for testing with self-signed certificates, support for environment variables, and new Lambda modifiers to customize the testing environment. The update also includes color-coded logs for better user experience, and compatibility with Docker images, though it requires modifications in test scripts to align with the Docker network topology. Additionally, the legacy binary remains available, and the update introduces support for the latest browser versions and fixes to enhance overall user experience. LambdaTest continues to offer 24/7 support to ensure smooth operation of these new features.
