Allow developers to start Guard inside backend-test container instead of sleeping. This allows to run tests automatically on source files change while existing testing method via
docker exec
still can be used.Guard can be started by setting START_GUARD environment variable to "1". Otherwise it's behavior stayed the same.
Also, we can use docker attach and stop code with binding.break(tty and stdin options in compose files enabled).
And it's possible(not sure, as I didn't try) to use debugger gem's protocol to integrate with IDEs and test editors.
