Create a sanbox of 20 users where the tests can be run prior to being committed to the real test.

I have run the load tests twice only to find out the csv had errors in it.    There isn't a way to run the script to test the script until it is put into a load test scenario which takes away from allotted time for testing.  The 3rd time it ran smoothly.  

Would be great if there was a way to test the script before committing it to Load test.  The playback did not go through all the csv data entries to have them verified.

Pretty sure no other SaaS performance testing tool has this either. The problem is that you would either have to run a very long verification with a single VU consuming data, or a shorter verification with many VU's consuming data. Either of these cases would be creating cost for SmartBear. It would be easier/less expensive if a process merely validated certain things about the data (such as no illegal characters...etc.). Unfortunately, the kind of data errors you are describing, could only be checked by actually having a VU use the data in server requests.

Actually Blazemeter has a sandbox that allows users to run the script prior to committing it to the actual load - it is a  free low-scale test for debugging purposes.   I suppose the playback would be considered a sandbox that finds object errors.    I can always go back to using JMeter.   I was able to run the script all the way through and validate the data prior to committing it to the cloud.

BlazeMeter allows for 20VU for this run?

[PeggyP]

Yes.   And it is free.

good to know. Thanks!
