Devel::Cover usage with a wrapper and a .pm module with a test script

I have a .pm module (Main.pm) which has a wrapper around it written in perl(Mainwrapper). These two are part of development team. I have written a test script in perl to test the wrapper(Testwrapper.pl). Now, I need to get the coverage using Devel::Cover for the wrapper(written by someone else) and its test script(written by me). The Mainwrapper of course uses the .pm module.

I tried using perl -MDEVEL:COVER Testwrapper.pl after having all Mainwrapper Main.pm and Testwrapper.pl in the same directory. Also included Main.pm in the Testwrapper.pl code. I could only get coverage for Testwrapper.pl and the Main.pm module in the report. One workaround I performed was to rename the Mainwrapper as Mainwrapper.pm and included in the Testwrapper.pl file. This would give me coverage for all. However, this is not a long term solution. Can anyone please tell me how to go with this?

I'm a bit confused about the different modules and scripts. But I gather that you have a module Main.pm, two wrapper modules using Main.pm, and two scripts using the two wrapper modules.

By running perl -MDevel::Cover script1.pl and perl -MDevel::Cover script2.pl you create two directories in cover_db/runs. Then you can run the command cover. This will generate the file cover_db/coverage.html. Open the HTML file in a browser and you should see a merged report containing script1.pl and script2.pl.
