For measuring power and strength, I favor using 1 rep max lifts : - overhead/front/back squats, deadlifts - cleans, snatches, jerks And throw in some: - vertical/long jumps - sprints This way it's cheap and easy to measure how an athlete is progressing through training. Although, I'm having a hard time coming up with alternatives that are boxing specific for measuring strength/power. Pretty much all other sports uses these as well. For agility, I guess you can use timed footwork drills similar to the ones they use in football but maybe alter them to mimic boxing movements.
Lose Fitness, you lose Body skills, Every circuit is a Test. But its important to spend time, on Motor Skills, I do. Integrating Bio mechanical excellence of Form of movement. With a Brain and Bottle it usually works out fine . Interestingly this can be done without Boxing, its all about the neural pathways adaptability and response.

For a lot of people, skills declining when they're fatigued is just a psychological thing. Obviously, it's a pretty big obstacle to overcome (control when you're fatigued), but a lot of people don't truly know their limits and they think they'll pass out, so it gets in their head. That's why I've always wanted to try drown proofing. My brother is a Navy SEAL, and they obviously drown proof, and he says it's a great way to actually assess how much your body can take. A lot of people think they can't push any harder than they do or they'll die, literally, but you'd be surprised how much your body can take after you try drown proofing (wouldn't recommend doing it by yourself, LOL). Also, water is really calm and if you can learn to control yourself underwater, you should have no problem controlling yourself when you're fatigued. Just my perspective on it.
I think heart rate monitoring sparring sessions and what not is a good way to see where your fighters fitness is at, looking at their heart rate levels and recovery. Repeated sprints over a short distance with little break in between is relevant to boxing IMO, seeing how they handle that is a good way to guess their level of lactate tolerance. Beep test, agility drills.. Maybe a power test with a medicine ball??
I was once trained by an old guy in Vegas named John Black. He has a site called Ringstars.com. He had quite a few test that he performed to assess baselines and improvement. Some of it is pretty common now. We ran shorts sprints like the 40 some days, but mostly we ran 1/2 mile sprints full out with one minute rest. He would document your hr between sets. I also was required to document my morning HR before I got out of bed. He also used an UBE machine, and I did upperbody sprints on it. HR and intensity was documented to the hilt. He also kept very close records of how many clap ups that I could perform, and full release pull ups. It's been almost 10 years, but this is what I can remember well. I don't think that I have since been bombarded with what seemed like so many mundane details.
