NOTES

App::Prove usage

Both prove and prove_cover use App::Prove. The only difference is this line, added to prove_cover:

 $app->{'exec'} = q{/usr/bin/perl -MDevel::Cover=-db,} . $db_path;

That said, prove_cover should be a drop-in replacement for prove, and work the same way (in the 'running tests' part).

Devel::Cover usage

Since prove_cover must run all tests under Devel::Cover, ther are run by: /usr/bin/perl -MDevel::Cover=-db,/foo/bar/cover_db. /foo/bar/cover_db is the current working directory.

Devel::CoverReport usage

At this point, there is no way to pass options to Devel::CoverReport. This may change in future release. Report will be generated as Html output, with all options set at their default values.

KNOWN ISSUES

I have observed many times, that when running many tests at once can corrupt Devel::Cover database and thus produce false statistics.

Running with -j 1 (default) should be a safe bet.

WARNING

Consider this script to be an early ALPHA. It does the job for me, so it's here.

This is my first CPAN module, so I expect that some things may be a bit rough around edges.

The plan is, to fix both those issues, and remove this warning in next immediate release.
