Claim:
A method in a data processing system for presenting coverage data relating to data access occurring during execution of code, the method comprising: obtaining the coverage data containing data access indicators associated with memory locations; identifying the data access indicators that have been set by a processor in the data processing system in response to access of the memory locations during execution of the code by the processor to form set data access indicators, wherein each set data access indicator is associated with a portion of the memory locations allocated for the code; identifying unset data access indicators that have remained unset during execution of the code by the processor; and generating a presentation for coverage data in response to an event for identifying memory locations that have been accessed and for identifying memory locations that have not been accessed during execution of the code, wherein the presentation for coverage data comprises a first presentation for the set data access indicators and a second presentation, different from the first presentation, for the unset data access indicators.
