SoapUI Groovy: Brazilian Gerador de CPF CNPJ

Hi, 

To Brazilians that use ID, CPF and CNPJ, for the Test Cases, i got this in javascript and convert to Groovy, is it OK:

Here, I'd just used log.info but you can use any code to try them.

log.info gerarCPF(true)
log.info gerarCPF(false)
log.info gerarCnpj(true)
log.info gerarCnpj(false)

// codigo para gerar CPF
// codigo copiado de http://gerardocumentos.com.br/?pg=funcao-javascript-para-gerar-cpf e transformado para groovy
int randomiza(n) {
ranNum = Math.round(Math.random()*n);
return ranNum;
}

int mod(dividendo,divisor) {
return Math.round(dividendo - (Math.floor(dividendo/divisor)*divisor));
}

String gerarCPF(boolean comPontos) {

n = 9;
n1 = randomiza(n);
n2 = randomiza(n);
n3 = randomiza(n);
n4 = randomiza(n);
n5 = randomiza(n);
n6 = randomiza(n);
n7 = randomiza(n);
n8 = randomiza(n);
n9 = randomiza(n);
d1 = n9*2+n8*3+n7*4+n6*5+n5*6+n4*7+n3*8+n2*9+n1*10;
d1 = 11 - ( mod(d1,11) );
if (d1>=10) d1 = 0;
d2 = d1*2+n9*3+n8*4+n7*5+n6*6+n5*7+n4*8+n3*9+n2*10+n1*11;
d2 = 11 - ( mod(d2,11) );
if (d2>=10) d2 = 0;
retorno = '';
if (comPontos) cpf = ''+n1+n2+n3+'.'+n4+n5+n6+'.'+n7+n8+n9+'-'+d1+d2;
else cpf = ''+n1+n2+n3+n4+n5+n6+n7+n8+n9+d1+d2;

return cpf;
