Slaven, I tried to do what you suggested, but without success:
use strict;
use warnings;
use Test::More;
#
# Skip tests if required modules are not available.
#
if (!eval { require Regexp::Common; 1 }) {
plan skip_all => "Regexp::Common moduled required";
}
if (!eval { require Image::Info; 1 }) {
plan skip_all => "Image::Info moduled required";
}
plan tests => 1;
#
# Load module under test.
#
use Graphics::Fig; # uses the modules checked above
....
When "plan skip_all" is executed, it exits the script without allowing control
to continue after the statement. So my expectation was that the "use
Graphics::Fig" below would not be executed if one of the tests above failed.
But it seems that perl looks ahead and processes all "use" directives before
starting execution of the script; therefore, if Graphics::Fig has unsatisfied
dependencies, the script blows up before executing the module check code at the
top.
I tried to force the execution order by putting the module tests inside a BEGIN
block. That also didn't work.

Subject: Re: tests failing due to dependency on Regexp::Common
Something like this could work:
use Test::More;
plan skip_all => "Regexp::Common required for test" if !eval { require
Regexp::Common; 1 };
plan tests => ...;
