I use a plastic film cannister (a Fuji Neopan 1600 grey one). Into
that I put about a single shot off a roll of Plus-X (cheap and
develops quickly) on which I have 36 identical shots of a grey scale.
The emulsion is towards the inside, so it doesn't matter if the
outside sticks to the can. Into that I pour straight developer, then
develop, fix - don't bother with wash, and inspect. It's easy to tell
if the developer is good. I've done this for a long time with other
developers, as in years past I've succumbed to trying to use old
developer and regretted it. It do this whenever I have any doubts.
The whole process takes about 6 minutes or so. I keep the exposed
roll in another film cannister; scratches are of no concern.
