Automating Tests in Elixir Projects

This post explores different ways to do test automation in Elixir, focusing on how to handle dependency injection — covering patterns, libraries, challenges, and trade-offs along the way. It walks through a series of real attempts using tools like Mock, Mox, ProcessTree, Hammox, and Double, all in the pursuit of fast, simple, and frictionless testing. Part of an ongoing series to explore the “perfect” Elixir setup.
