Smart TV Testing Made Simple with Dave Lucia of TV Labs

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.Guest: Dave Lucia, CTO & Co-Founder at TV LabsDave is a technology leader with deep experience designing and scaling systems across industries including media, sports betting, finance, and developer tooling. He is a prominent member of the BEAM community, regularly speaking at conferences such as Code BEAM SF, ElixirConf, The Big Elixir, and RabbitMQ Summit.Dave Lucia, WebsiteDave Lucia, XDave Lucia.
