I'm not sure what are you asking, but if you want to call an arbitrary function, you can create a 'Cmd' object with the relevant args. So, if your module has a 'FOO.SET' command that takes a key and a value, and you have a connection object 'conn', you'll call it with '''rs redis::cmd("FOO.SET").arg(key).arg(val).query(&mut conn)

You can't, ATM. You can either copy the code to your repo, with the appropriate attribution, or you can to open a PR to add another crate to this repo (let's call it redis-test-utils), copy the context code to the new crate, and consume that crate from your repo's tests. @jaymell, does that sound reasonable to you?
