Hi Minh,
I just saw the message. There are at least two ways to do that:
Add all the apps to TestedApps, with all the configuration required. Once you have done that, create a script and execute a loop with all the apps with RunTestedApp method.
Launch them from Command Line. Create a script and launch cmd from there. Retrieve the object, and loop the app execution from inside of it.
The first way is the best, as it's faster and has less probabilities to fail at any point. Just make sure the command line is correct. If you need to, you can change its properties from the scripts.
Hope it helped
