Testing Shell Scripts with Bats
This post explores how to test shell scripts — something relevant to many Elixir projects that rely on shell scripts to power development- and CI-workflows. It walks through the motivation, trade-offs, and practical ways to assert shell script behavior using simple techniques inspired by Mix conventions. Part of an ongoing series to explore the “perfect” Elixir setup.
