How do I write unit tests in Perl

Unit testing in Perl can be done using the built-in module called Test::More. This module provides a simple and powerful way to write tests, allowing you to verify that your code works as expected.

Example of Unit Testing in Perl

Here's a simple example demonstrating how to write unit tests for a Perl module:

# MyModule.pm package MyModule; use strict; use warnings; sub add { my ($a, $b) = @_; return $a + $b; } 1; # return true value to indicate success # test_MyModule.pl use strict; use warnings; use Test::More; use lib '.'; # Add current directory to @INC use MyModule; # Test cases is(add(2, 3), 5, '2 + 3 is 5'); is(add(-1, 1), 0, '-1 + 1 is 0'); is(add(1.5, 2.5), 4, '1.5 + 2.5 is 4'); done_testing();

To run this test, simply execute the test_MyModule.pl script. It will output the results of the tests, indicating whether they passed or failed.
