How to test scale constraint in grails

Question

In Grails domain class i have Field

BigDecimal grossWeight

and constraint for it

static constraints = {
      grossWeight(nullable: true, min: BigDecimal.ZERO, scale: 3)
   }

I like to have test for scale constraint but don't know how to implement it

Following not works

formxItem = new FormXItem(grossWeight: new BigDecimal("0.1234"))
assert !formxItem.validate()
assertNotNull formxItem.errors['grossWeight']

did you use mockForConstraintTests ! – Sudhir N Jun 25 '12 at 12:34 — Sudhir N, Jun 25 '12 at 12:34

According to the documentation for scale, the constraint does not register any validation errors, so it will not fail validation. Instead it sets the column's precision in the database and automatically scales down the precision of the number, if necessary.
