Once you have generated a test script, determine if the script runs without error by executing a Try Script run. A Try Script run determines if a script accurately recreates the actions that you recorded with the Browser Application-Based Recorder. It also determines if the script contains any context-specific session information that you must parameterize before the script can run error free.
With Try Script runs, only a single virtual user is run and the stress test option is enabled so that there is no think time or delay between transactions.
