This post is the written companion for my video on TestItems.
Liking and subscribing there is appreciated.

TestItems is a modern testing framework for Julia allowing parallel testing, isolation, setup steps, and filtering.
It has a nice VSCode integration, and through TestItemRunner, it can be used with Revise to automatically rerun tests, or by AI agents via julia-mcp to improve iteration speed.
The official website is https://julia-testitems.org/.

This post is aimed at anyone developing packages in Julia.
