As a beginner, it's often hard to get a real idea of how you're doing. I've got a couple of tools I've used to do so on the offchance that it's helpful.
The multistage fitness test AKA 'bleep test'
People often ask about cardio when they first start. This should give you a good idea of how you're actually doing, cardio-wise.
You do need the recording.
I have eschewed one rep max testing for some time on the basis that it's not meaningful at my level.
5RM and 3RM tests are probably safer, but maybe still a problem because your max will probably actually go up as a result of the test itself.
As for exercises, I think it's wise to stick to the powerlifts, max pullups, and the clean.
So what more is there? I like to do max burpees in 5 minutes as a GPP test. I'm aware of the PFT (a mile run, max pushups, max situps).
