What is mocking in tests (Test::MockModule) in Perl?

Mocking in tests using the Test::MockModule in Perl allows developers to simulate the behavior of certain modules or functions without invoking the actual implementations. This is particularly useful for isolating the code being tested and controlling the environment in which the tests run. By mocking functions, you can test how your code handles various situations without relying on external dependencies.

use Test::MockModule; # Creating a new mock module my $mock = Test::MockModule->new('Some::Module'); # Mocking a method in the module $mock->mock( 'some_method', sub { return 'mocked_value'; } ); # Now, when you call Some::Module::some_method, it will return 'mocked_value' use Some::Module; my $result = Some::Module::some_method(); print $result; # This will print 'mocked_value'
