Hi Guys

You can generate a random string in Setup Script of test case, save it as test case level custom property  and use it all the steps of test case using Property Expansion.

See below link to

//Courtesy: http://stackoverflow.com/questions/8138164/groovy-generate-random-string-from-given-character-set

def generator = { String alphabet, int n ->
  new Random().with {
    (1..n).collect { alphabet[ nextInt( alphabet.length() ) ] }.join()
  }
}

//Provide the length of the string, here it generates 9 characters
def id = generator( (('A'..'Z')+('0'..'9')).join(), 9 )

//Save it into custom property
testCase.setPropertyValue('ID', id)

How to use above generated id in steps?

• If the step is of Groovy Script test step, then use below to get the id - context.expand('${#TestCase#ID}')
• If the step of Request type step, then use below - <elementId>${#TestCase#ID}</elementId>

By the way, request you to properly provide the summary of the problem while creating the topic in the forums instead of using unsuitable one like you wrote "Hi Guys".
