difference between Single Pass Execution Entry Point and executing a sequence directly in teststand

[rj_501]

hi, 

I am new to teststand , i would like to know, what is the difference between Single Pass Execution Entry Point and executing a sequence directly. To executing a sequence directly, there is an option execute> run main sequence. For Single Pass Execution Entry Point , there is an option at execute> single pass. Here they both start from main sequnce and both doesnt ask UUT information. Can anybody tell the diffrence between these two?

Thank you

RJ

Run MainSequence is an interactive execution.  Meaning it does not use the process model.  The process model is what generates the reports and displays various dialogs.  The process model also provides other callbacks that you can override such as: ProcessSetup, ProcessCleanup, PreUUT, etc...

Single Pass runs with the process model.  You will get a report or log to a database.

Here is some more info on callbacks:

Here is some good info on the process model:
