Also, the database can be changed quite easily to use in-memory SQLite: app.databases.use(.sqlite(.memory), as: .sqlite) Doing that would allow a unit test to be quite lightweight. However, I had some issues with that approach. This post is about explaining what that issue was and how I ended up changing my unit tests to use PostgreSQL directly....

Docker is quite a famous piece of tech. It solves the problem of making software that runs easily across machines (mostly for Linux servers). I won’t get into details, but it uses Kernel level functions to isolate containerized programs so that we don’t need to bother about installing the right dependencies on every machine we want our software to run. Instead, we build a docker image, publish it and whoever has docker in their machine can then run it as well as long as the machine has Docker installed....
