With Tesitmony v2.21 a number of enhancements have been made to the playback simulation program to allow you to understand the requirement on the bots prior to building the execution queue. In this version of the pre-playback simulation, you must still have created a recording, and it is on the data in this recording that the pre-playback simulation will process.
The key output of the pre-playback simulation is to give you a heads up on the expected run-time of the playback and how many bots you will require.
The program name is /BTI/AUT_EARLY_PLAYBACK_SIM. It should be run upon the central system only. You specify the test plan ID and the number of worker jobs you have available for use in the central system to facilitate the playback. You should also specify how many background jobs you expect to have available on the target system when you run the playback.
The sequencing strategy should be set to 02 (full throttle) unless for smaller playbacks you intend to use sequencing strategy 01. You can also specify the time frame to obtain an estimate on what the playback will do every N minutes.
A sample of the select-options for the program is shown below:
