What do you feel is the purpose of krav tests?

Lots of think-y threads lately, I know! A comment in another thread about 90 minute tests got me thinking. My gym's tests are closer to five hours. Are my gym's tests better? I realized that I genuinely don't know. What does "better" look like when it comes to a krav test?

I can think of a list of things that krav tests can accomplish:

• Test if you know the checkpoints of the techniques and can physically do them

• Test if you can perform the techniques exhausted and under stress

• Test the smoothness/flow/quality of your techniques

• Test your general physical fitness

• Test your mindset/attitude/fighting spirit

• Test your sparring/fighting ability (usually not for P1 tests)

• Test your scanning/awareness/problem-solving

• Verify that you have enough control of yourself to be safe to train with at a higher level

• Verify that everyone taking the test is on the same page - you don't have one group all doing a technique differently because one instructor teaches it differently

• Make you feel like you've accomplished something by taking the test

• Gives you a concrete goal to train for in the future

• Give you bragging rights ("I passed my eight hour test that my Marine buddy said was harder than boot camp! I only threw up once!")

• Get everyone through the test without significant injuries (Included because in practice, this goal sometimes conflicts with some of the others)

Which of these things do you think are most important? Are there any that you think aren't important? (I'm sure some will say bragging rights aren't important at all, and you may be right, but how many people got into krav because of a friend's story about an epic test or training session? Why do traditional martial arts break boards? Is it worth it? I don't know.) Is there anything I'm missing - I probably am, since this was off the top of my head.

What does your ideal krav test look like? How does it accomplish the goals that you feel are most important?

Or, are you of the opinion that krav doesn't need tests at all? That krav shouldn't be separated into levels (which is a whole different discussion) or that instructors should just promote students when they're ready without bothering with tests?
