Recursive method call representation in a plot view of method execution performance

A performance testing data processing system comprising:

• a host computer with memory and at least one processor;
• a performance test application executing in the memory of the host computer;
• a stack of data point objects in the memory, each data point object comprising a start time data member, a duration of execution data member and a parent-child relationship data member;
• and,
• a plot view generation for recursive method calls module coupled to the stack and the performance test application, the module comprising program code enabled upon execution in the host computer to plotting a duration of execution for method calls in a visual plot according to traced entry and exit points for the method calls, and to visually display a recursive relationship between selected ones of the method calls in the visual plot in response to determining a recursive relationship from the traced entry and exit points.

A computer program product for graphically representing recursive method calls in a plot view, the computer program product comprising:

• a non-transitory computer readable storage medium comprising a memory device having computer readable program code embodied therewith, the computer readable program code comprising:
• computer readable program code for tracing entry and exit points for method calls in an executing computer program subject to performance testing in a performance test application executing in memory of a computer;
• computer readable program code for plotting a duration of execution for each of the method calls in a visual plot according to the traced entry and exit points;
• and,
• computer readable program code for visually displaying a recursive relationship between selected ones of the method calls in the visual plot in response to determining a recursive relationship from the traced entry and exit points.
