Test2::Tools::Class(3) User Contributed Perl Documentation Test2::Tools::Class(3)

Test2::Tools::Class - Test2 implementation of the tools for testing classes.

Test2 based tools for validating classes and objects. These are similar to some tools from Test::More, but they have a more consistent interface.

    use Test2::Tools::Class;
    isa_ok($CLASS_OR_INSTANCE, $PARENT_CLASS1, $PARENT_CLASS2, ...);
    isa_ok($CLASS_OR_INSTANCE, [$PARENT_CLASS1, $PARENT_CLASS2, ...], "Test Name");
    can_ok($CLASS_OR_INSTANCE, $METHOD1, $METHOD2, ...);
    can_ok($CLASS_OR_INSTANCE, [$METHOD1, $METHOD2, ...], "Test Name");
    DOES_ok($CLASS_OR_INSTANCE, $ROLE1, $ROLE2, ...);
    DOES_ok($CLASS_OR_INSTANCE, [$ROLE1, $ROLE2, ...], "Test Name");

All subs are exported by default.

This checks that $thing (either a class name, or a blessed instance) has the specified methods.

If the second argument is an arrayref then it will be used as the list of methods leaving the third argument to be the test name.

This checks that $thing (either a class name, or a blessed instance) is or subclasses the specified classes.

If the second argument is an arrayref then it will be used as the list of classes leaving the third argument to be the test name.

This checks that $thing (either a class name, or a blessed instance) does the specified roles.

If the second argument is an arrayref then it will be used as the list of roles leaving the third argument to be the test name.

Note 1: This uses the "$class->DOES(...)" method, not the "does()" method Moose provides.

Note 2: Not all perls have the "DOES()" method, if you use this on those perls the test will be skipped.
