Not enough test cases. My first solution passed "Attempt" (and submitted against my will), even though it resulted in exception in "Test" when I added a test case ("allisonname", "allison")

Python: almost all random tests expect False. return False passed all random tests after a couple of resubmits (see this solution).

the formula is incorret.
the correct formula is
BAC% = ((A * 5.14 * r)/W) - 0.015 * H

For what is 'abv' here? It doesn't appear in Formula.

So is the second string guaranteed to contain only letters or there may be special characters too?

Java: no fixed tests for case insensitiveness. (And the random tests rarely generate such cases.)

If str and name are both empty, then the result should be true or you should say that they are not empty (str.length and name.length > 0). Sorry for my bad English :)

Better to not rely on an encode that solvers can get their dirty little fingers on.

Define and use your own.

Duplicate of every other "turn math function into a programming function" kata. Should never have been approved.

The actual/expected values should be compared for approximate equality.

Duplicate Kata if I remember correctly
