This post explains how to run Protractor tests using Sauce Connect behind a corporate firewall. The author initially struggled with setting up the process due to incorrect assumptions about the Sauce Connect binary's location and dependencies. To overcome these challenges, they utilized Gulp as a build manager and required the `sauce-tunnel` package, which simplifies the setup process. The author provides a step-by-step guide on how to configure Gulp to run Protractor tests through Sauce Connect, including setting up tunnel-identifier values, installing dependencies, and modifying configuration files. They also offer solutions for common issues such as proxy-related errors and lingering sauce connect instances. Ultimately, this tutorial demonstrates how to successfully integrate Sauce Connect with Protractor in a corporate environment, enabling end-to-end testing behind firewalls.
