I will tell you how you can manage it and choose the appropriate behaviour for your application.
On the Files/Settings/Run you have 4 choices when an error occured:
- popup message box
- proceed to next action iteration
- stop run
- proceed to next step
The more convenient for testing is to set "proceed to next step" because when an error occured, the system will go to the next step and report the issue in the reporting.
But for debugging, the popu message box could be useful.
