Normal -displays execution marker for showing the current execution step. It will be useful for debugging the script execution.
Fast– won’t show the execution marker, so the execution will be faster than the normal run mode.
Update Run– QTP is having Update Run mode for updating test object descriptions, the expected checkpoint values, and/or the Active Screen images and values.
Choose Automation >Update Run Mode for running the scripts in update mode.
When QuickTest updates a test, it does not update parameterized values, such as Data Table data and environment variables.
