def num = generateRndString(10, "numeric");
log.info num
def str = generateRndString(10, "string");
log.info str
def alphaNum = generateRndString(10, "alphanumeric");
log.info alphaNum
testRunner.testCase.getTestStepByName("Properties").setPropertyValue("RndNum", num)
testRunner.testCase.getTestStepByName("Properties").setPropertyValue("RndString", str)
testRunner.testCase.getTestStepByName("Properties").setPropertyValue("RndAlpha", alphaNum)

def generateRndString(int num, String type){
	def randValue = "";
	if( type.equalsIgnoreCase("numeric") ){
		def alphaNumeric = ('0'..'9').join()
		randValue = RandomStringUtils.random(num, alphaNumeric)
		while (randValue.size()!=num)
		{
			randValue = RandomStringUtils.random(num, alphaNumeric)
		}		
	}
	else if( type.equalsIgnoreCase("string") ){
		def alphaNumeric = (('a'..'z')+('A'..'Z')).join()
		randValue = RandomStringUtils.random(num, alphaNumeric)
		while (randValue.size()!=num)
		{
			randValue = RandomStringUtils.random(num, alphaNumeric)
		}
	}
	else if( type.equalsIgnoreCase("alphanumeric") ){
		def alphaNumeric = (('0'..'9')+('a'..'z')+('A'..'Z')).join()
		randValue = RandomStringUtils.random(num, alphaNumeric)
		while (randValue.size()!=num)
		{
			randValue = RandomStringUtils.random(num, alphaNumeric)

    import org.apache.commons.lang3.RandomStringUtils
import org.codehaus.groovy.runtime.DateGroovyMethods

def getRandomAlphanumeric(int len, String format="MMddkkmm") {
  try {
	format.size() < 1 ? RandomStringUtils.randomAlphanumeric(len).toUpperCase() : \
	DateGroovyMethods.format(new Date(), format).concat(RandomStringUtils.randomAlphanumeric(len).toUpperCase())
} catch (Exception e) {
	throw new Exception(e)
 }
}
