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();
