Comparing Purify Coverage Data from Two Runs

Related Topics

 

1.    Select a run whose coverage data you want to compare. To select a run, click a coverage tab for the run, or select a run in the Navigator.

2.    Click images\diffic.gif

3.    Select a run (identified as the Base run) to compare against the first run (identified as the New run, and also labeled Current run in the Compare Runs dialog box).

Notes:

§      In the Annotated Source window, Purify displays the differences (labeled Diff), as well as original data for the two runs (labeled New and Base). Positive values indicate coverage improvements.

§      In the diff coverage tabs, Purify displays the original data for the two runs (labeled New and Base).

§      When you compare runs from programs that have been modified between runs, the annotated source code will not be completely accurate because the source lines represented by each of the runs are different.

§      For the results to be meaningful, compare runs that use the same coverage level for each module. For example, if a run used line level, the run you compare it against should have used line level as well.

§      The Details tab of the Run Summary window identifies the runs that were compared.
