NAME Test::Mock::Class - Simulating other classes SYNOPSIS use Test::Mock::Class ':all'; require Net::FTP; # concrete mocked class mock_class 'Net::FTP' => 'Net::FTP::Mock'; my $mock_object = Net::FTP::Mock->new; # anonymous mocked class my $metamock = mock_anon_class 'Net::FTP'; my $mock_object = $metamock->new_object; # anonymous class with role applied my $metamock = Test::Mock::Class->create_anon_class( roles => [ 'My::Handler::Role' ], ); my $mock_object = $metamock->new_object; DESCRIPTION In a unit test, mock objects can simulate the behavior of complex, real (non-mock) objects and are therefore useful when a real object is impractical or impossible to incorporate into a unit test. The unique features of `Test::Mock::Class': * Its API is inspired by PHP SimpleTest framework. * It isn't tied with Test::Builder so it can be used standalone or with any xUnit-like framework, i.e. Test::Unit::Lite. Look for Test::Builder::Mock::Class if you want to use it with Test::Builder (Test::More or Test::Simple). * The API for creating mock classes is based on Moose and Class::MOP so it doesn't clash with API of original class and is easy expandable. * The methods for defining mock object's behavior are prefixed with `mock_' string so they shouldn't clash with original object's methods. * Mocks as actors: The mock version of a class has all the methods of the original class. The return value will be `undef', but it can be changed with `mock_returns' method. * Mocks as critics: The method of mock version of a class can check its calling arguments and throws an exception if arguments don't match (`mock_expect' method). An exception also can be thrown if the method wasn't called at all (`mock_expect_once' method). BUGS The API is not stable yet and can be changed in future.
