built-in testing trigger

[FranksRobins]

Hi there uvicorn team,
First of all I would like to thank you for making uvicorn uvicorn. While using it for development with Fastapi I found that I could use a testing functionality. Now maybe I have misread the docs but it seems like there is no such thing currently available. I think a exec trigger that would be passed as an argument when launching uvicorn would be helpful. Something like

--with-exec="path/to/command/or/script" 

that would be used in pair with the --reload argument could help while in development. This specific command (or script) would be run every time the server reloads after a change in the code source.

A complete example would look like the following:

uvicorn my_api:app --reload --with-exec /usr/local/bin/my_api_test

That script could be some simple curl requests to test the endpoints or a more elaborated testing unit.

I found that this simple functionality would be a great help when developing locally. If there is already something similar, I would be happy to be aware of it. If I am missing something I would also be happy to be aware of it!

Thanks

While I'm very dubious we should add that feature, I'm still interested in knowing what kind of issue for the developper it would solve ?
