I have had all kinds of test pressings and have made some limited observations.
The earliest test pressing I have is of Tubby Hayes which looks like from the Decca factory. It is the Jazz Couriers and is 2 mono discs one side blank each. I assume Tempo stuff was pressed by Decca.
I have a one sided disc for Zoot Money 1966 only from EMI. This has the security sealed sleeve with identifiers rubber stamped and dated on sleeve
later on in the decade I have had 2 EMI discs for a single LP one side blank through to the late 1970's.
Are there any hard or fast rules and were these test pressings routinely destroyed and what I have is just the LP's being liberated from the factory.
I wouldn't have thought they'd be destroyed. Thrown away maybe, but I'll be the staff who worked there took plenty home with them. After all, they had no intrinsic value at the time.

I've had quite a few, in fact I have a zoot money on 45cat, this has homemade artwork on the label either by a fan or somebody but it is typically sixties & old so must have escaped the factory.
I am going to guess apart from some scenes I saw on video** the process was:
that the test pressings were printed then moved to another persons office to play through to check for tracking faults. If they were ok then went to management to approve. Thereafter given away or thrown away.?
**cant remember...
(I should add I have had pre 50's 78rpm test pressings as well)

so would I but that means climbing into the garage, if I kept them? I remember an acetate style one with a plain yellow label with a (wotsit) patern round the edge.
I think acetates and similar sound test pressings probably existed from the start of the 78 era but Demonstration & Promotion (review) copys maybe starting in the 40's in USA. There is a French example ..from 1932
