How do you test code that uses coverage (Devel::Cover)?

Testing code that uses coverage can significantly improve the quality of your code and help identify untested parts. The Devel::Cover module in Perl provides a way to analyze code coverage. This includes gathering information about which parts of your code are tested and which are not. Here’s a simple example of how to use Devel::Cover to test your Perl code with coverage.

#!perl use strict; use warnings; use Devel::Cover; # Sample code to be tested sub greet { my ($name) = @_; return "Hello, $name!"; } # Test the function sub test_greet { my $result = greet("World"); die "Test failed!" unless $result eq "Hello, World!"; print "Test passed!\n"; } test_greet(); # Run coverage analysis Devel::Cover::start(); Devel::Cover::stop();
