Devel::Cover HTML output
I am playing around with Devel::Cover to see how well our test suite is actually testing our codebase. I run all of our tests using -MDevel::Cover nothing seems to fail or crash, but the HTML output of the coverage table has entries like these for all of our Modules:
The number of BEGINs listed seems to match the number of use Module::X statements in the source file, but really clutters the HTML output. Is there any way to disable this feature? I don't see any mention of it in the tutorial or the Github issue tracker.
The reason for this is that "use" is "exactly equivalent to"
BEGIN { require Module; Module->import( LIST ); }
(See perldoc -f use.)
And then "BEGIN" is basically the same as "sub BEGIN" - you can put the "sub" there if you want to. See perldoc perlmod.
So what you really do have is a subroutine, and that is what Devel::Cover is reporting.
Like many parts of Devel::Cover, the details of perl's implementation, or at least the semantics, are leaking through. There is no way to stop this, though I would be amenable to changes in this area.
