How do I run some effectful code before tests are run?

[rocky lynx]

The title pretty much says it all. I need to start a binary and set up a docker container before my tests are run.

I am actually using tokio::test but I am curious about what the general solution to this problem is as well.

Put all your stuff in one test?

Generally, this kind of situation is hard to manage because it’s best avoided in the first place (i.e. prefer I/O-less solutions where you can do purely in-memory, cheap to set up and cheap to tear down tests)

So ideally the solution would be “redesign your code so you don’t need to do this”
