If you are running out of time, create some Q&D (quick & dirty) code. OO in Perl con be mixed into regular scripts. The thing you will need is the documentation for the objects. You will need to know what objects and methods each object has available.

For example: When you use DBI to access a database, you are actually using an object. Logging on to the server you use

DBI->Connect

. That is using an anonymous object created by the DBI package to create a connection to the database. You are required to pass it parameters. The documentation tells you what parameters to use.

You might be able to write scripts and use the objects in the toolset for specific tests.

I think that with time you will be able to understand what the creator of the toolset wanted. In the meantime, you can override methods or create your own inherited objects to test the toolset.
