How to Debug QTP scripts

Debugging in QTP is very simple like other programming languages There is one toolbar called debug viewer in QTP which helps us to debug the QTP scripts. You can add breakpoints to any line in qtp code by clicking on the extreme left to line where you have to add breakpoint. Code will pause at the breakpoint. Shortcut keys for working with breakpoints are - F10 - Step Over Block of Code F11 - Step Into Block of Code Shift+F11 - Step Out of Block of Code At this point you can use three tabs for debugging purpose. Watch - used to see contents of any variable. Variables - displays the current varaibles which are in scope. Command - you can give QTP commands from this tab.
