示例1: TestMoneyOverflow
func TestMoneyOverflow(t *testing.T) {
flag.Parse()
if ovf == 0 {
t.Skip("Skip overflow no 'overflow' cli flag set: 'ovf=1 will run it'")
}
r := random(1, 25)
m1 := money.Money{M: money.MaxInt}
m2 := money.Money{M: money.MinInt}
if (r % 2) == 1 {

} else {
_ = m2.Sub(&m1)
}
/*
** this was testing using fields on the struct to check for overlfow errors
// overflow error should return value of struct attempting op

if res.OvfErr != true {
