uuid.test() for uppercased UUID returns false

[Mesqalito]

const id = uuid();
console.log(uuid.test(id)); // true
console.log(uuid.test(id.toUpperCase())); // false

I think treating uppercased hexadecimals as invalid aren't right. test() function's regexp should be case-insensitive.

Yep I agree, great catch. Will push a fix.
