NAME covmerge.exe ‐‐ merged coverage info from multiple test runs SYNOPSIS covmerge.exe *.covexp >merged.db DESCRIPTION This script merges test coverage information produced by instrumented executables into a single database file. You typically run many instrumented programs many times each to get the collection of .covexp files. You then merge these many files into a single merged.db file for later processing. The merging process includes the creation of new information. The instrumented programs do not aggregate the information on a directory basis. covmerge.exe does this for you. You can examine the merged.db file yourself, but the easies way is to use the gen_html script to have it create web pages which you can then just peruse.
