Object::Exercise

Object::Exercise is a Perl module that offers a single subroutine known as $exercise. This subroutine functions as an object-oriented (OO) execution loop and can be renamed using '-n'. A subroutine reference, $execute, is also available. The $execute subroutine takes an object and a set of operations as arguments. The first element in the list of operations is an object from the class being tested, while the remaining elements are operations consisting of an array reference. Each operation includes a method call and method arguments.

All method calls are dispatched using the object, and optionally, the return value can be compared against a pre-defined result. In case there are any exceptions, they are trapped and logged. Additionally, the last operation can be re-executed if it fails. Operations are passed in as array references and can be nested to hold a list consisting of a method name and its arguments, or to store a return value and test to run.

One can use the module by adding the line, use Object::Exercise; to their code. The SYNOPSIS presents a sample code that contains a list of operations. The list of operations includes various scenarios such as checking for $@ and storing a return value. The user can push the operations through a class or object.

Overall, Object::Exercise offers convenient and efficient testing options for Perl modules. The ability to nest operations offers great flexibility in testing and the module is easy to use due to its clear syntax. Additionally, exceptions are handled efficiently, and the module offers the option of re-executing the last operation in case of failure.
