Hi Santosh,
> [...] i want to get the total elapsed time(i.e Wait time, Sync time and Timers) of script [...]
Not sure what you meant with "Wait time, Sync time and Timers", but if you like to get the total test execution time you may either
-- Switch to the Summary panel of the Log;
or
-- On the Project Log panel select the top element of the Log Items tree;
-- In the Project Log pane (the one on the right from the Log Items) right-click and select Show Summary in the context menu;
-- On the opened Summary right-click below the Run Time column and select Sum in the context menu.
Does this help?
