How do you test code that uses mocking in tests (Test::MockModule)?

Testing code that utilizes mocking can be essential for isolating the functionality of your application. One popular module for mocking in Perl is Test::MockModule. This module allows developers to override methods in a class for the duration of a test, enabling you to simulate various scenarios and behaviors without relying on the actual implementations.

Here’s a simple example to illustrate how you can use Test::MockModule to test a method:

use Test::More; use Test::MockModule; # Assuming we have a class MyApp with a function that we want to mock { my $mock = Test::MockModule->new('MyApp'); # Set up mocking for the 'some_method' method $mock->mock('some_method', sub { return 'Mocked response'; }); # Now, when we call MyApp->some_method, it will return 'Mocked response' my $result = MyApp->some_method(); is($result, 'Mocked response', 'The mocked method returned the expected response'); } done_testing();
