Testing smart TV applications presents unique challenges that traditional web testing approaches can't solve. Dave Lucia, CTO and co-founder of TV Labs, shares how his team built a platform that virtualizes televisions and set-top boxes to help media companies test their smart TV apps on physical devices.

Learn about TV Labs' innovative architecture and how they handle everything from camera-based testing systems to their custom Lua-based DSL for faster test execution. A key highlight is how choosing Elixir as their primary technology has enabled TV Labs to build a robust orchestration system. The language's built-in capabilities for fault tolerance, process isolation, and distributed computing make it particularly well-suited for managing concurrent connections and real-time state across multiple devices.

The discussion also explores practical insights about system architecture, including how TV Labs leverages Phoenix presence for real-time device state tracking and achieves microsecond-level performance for message broadcasting.
