images\coverage_sml.gifActiveMerge

A feature that causes coverage run datasets to be merged so that data from each contributing run is preserved as a layer that can be selected and de-selected in the user interace. You can use datasets merged under ActiveMerge to evaluate the contribution of each run, as follows:

§          Remove and add back individual layers by clicking them in the Navigator. The coverage data displayed in the user interface adjusts to show the effects.

§          Select a function or a line in the coverage data display. The check next to a layer turns red if the corresponding run did not hit the selected item.

By default, without ActiveMerge, coverage data is combined into an undifferentiated dataset, as if all the data had been collected from a single run.

To use this feature, select ActiveMerge in the Runs tab in the Preferences dialog box. The setting applies to all subsequent merges, both automatic and manual, until you deselect it.
