Same here I just wasn't paying enough attention to my solutions' logic
NOTE: NOTHING IS WRONG WITH THE KATA ITSELF(this is just for future people who will struggle with it)

Problem solved after a lot of work. :)

I want to know if the validate is supposed to have an '!'(in '!validate') because the ones expected to be true are turned false for no matter solution you try but if you add it the answer gets validated.
Test.expect(validate('djI38D55'), 'djI38D55 - Expected true'); // Doesn't work
Test.expect(!validate('a2.d412'), 'a2.d412 - Expected false'); // Works

Test.expect(!validate('djI38D55'), 'djI38D55 - Expected true'); // Works
Test.expect(!validate('a2.d412'), 'a2.d412 - Expected false'); // Works
