Is there a recommended way in Kotlin to validate a BigDecimal to confirm with e.g. totalDigits(10) fractionDigits(3) ?

No built-in mechanism in the standard lib exists that I know of… do you need to validate a BD in production code or do you need test assertions?

Anyway, BigDecimal provides two methods you could use:
• precision() — The precision is the number of digits in the unscaled value
• scale() — If zero or positive, the scale is the number of digits to the right of the decimal point.
so you could define your extensions on BigDecimal to check for those constraints
