on the run glue tests
When I have glued something up (shelf) and then there's a bit to be trimmed off with part of the glued joint I try to break it to too see how well it held, here's a couple of pics of such a join, the timber is Caphour Laurel with the joint being end grain to long grain...glue will have been either TB orig or TBII
It's only a trimming so only about 15mm wide, I held the block in one hand, the stick bit in the other with thumbs at join and then tried to open the join, took a little bit to do, like the title says I do these sort of quick ready rough test on the go, it gives me an idea of yep that's glued well or not so well

As can be seen in the third pic there's 90 to 95% timber failure which is not too bad for this type of joint, on thinking about this there's probably some reasons, the end grain on the long bit will have been planed (as part of the shelf build process) also the block piece will have had its edge planed prior to glue up to give a flat square clean join face, also the end grain will have had its end painted with glue and time allowed to suck up the glue then repainted again so as not to have a glue starved joint,
the shelf can be seen in my cabinet build WIP in big stuff shortly...they are finished
