I've often been able to alias drun='docker compose run --rm --build' and simplify down to:

drun test

Should be able to encode all those wayward args into docker-compose.yml or Dockerfile and only use vanilla docker commands -- that's the whole point of containerization

The env file is the weirdest part, the container itself has a required environment variable and if I don’t pass it in command line (only have it in the test compose file) the base compose fails because it has no port.

Most of the other commands are to merge the compose files so I can keep my base compose file clean!

Simpler to keep everything in one compose file if you can, under a test service that doesn't build unless explicitly named

Un-weird that env var and use the normal, boring feature of defining environment under your test service

The variable is already in the environment, it just doesn’t have a default because it’s required for each container

You can reference envs from the host in docker compose, so code it in instead of manually passing tribal knowledge in: https://stackoverflow.com/a/73826410

Yep, you can also set defaults, required, alternates, etc

This discussion did help me realize that my problem was that I forgot an !override on one of my service’s options. Now it’s just merging the two compose files and setting the profile, thanks for that!
