Moin,
as a fan of Devel::Cover I can't stress enough how usefull this module is.
Writing tests is easy, writing *good* tests is not-so-easy.
So, I tried to use Devel::Cover to coverage my testsuites. There are quite
some bugs and bumps, but these are hopefully straightened out ;)
Anyway, it is not so easy to run your entire testsuite trough Devel::Cover.
Well, sort it is:
PERL_DL_NONLAZY=1 /usr/local/bin/perl -Iblib/arch -Iblib/lib -e 'use
Test::Harness qw(&runtests $switches $verbose); $switches="-w
- -MDevel::Cover"; $verbose=0; runtests @ARGV;' t/*.t
takes care of that. Only problem is that the cover_db is created locally to
each testfile, and that can be a problem if your testfiles chdir to
different dirs.
But I thought it would be handy and encourage the usage of Devel::Cover
when we have make target(s) like:
perl Makefile.PL
make cover
make podcover
The former does anything, the latter only pod coverage. That way it would
be easier for module authors to do testsuite coverage. The make target
could also then print a summary. Currently you have then to do this
manually.
What do you think?
Cheers,
Tels
PS: The module is also great for profiling, it shows you for instance, that
my $x; my $y;
is nearly twice as slow as:
my ($x,$y);
which would be hard to find out with DProf (once you know, you can
benchmark it. But Devel::Cover shows this right in the source where it
happens without any special magic required). I really love it ;)
