Thanks for your help.
Is the list known in advance, or is it only known by extraction from a previous result? If the list is known in advance, then the easiest would be to write a script to create a file containing all the combinations. If you don't care if the criteria contain duplicates (e.g. DOG+CAT+DOG or DOG+DOG+DOG et.) then just concatenate the 3 random selections - no need for the random controllers. Otherwise, you will have to write some code (jexl, javascript or beanshell) to generate the criteria, in which case use the match-all Regex feature. Or it may be easier to write code to remove the duplicates from the concatenation. Something like: - split string on '+' - save unique values - join values using '+' If the order of items is not relevant then you can use a hash to eliminate duplicates. Otherwise you could use something like ListOrderedSet from Commons Collections (JMeter already includes the collections jar). If you use the Match-All Regex, then instead of splitting the string you can read the variables in turn into a Hash or a Set as above. > Regards, > hiro > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
