Use the search module anywhere in the site with a keyword wich should return one of the products from the Test category, for example "tests". If you don't see the Test product then the pludgin works. Is simple than that! 

The package can be obtained from our Downloads or from Joomla Extension Directory. Can be installed as any other Joomla component.

The package contains a Joomla component, a module and a plugin, all installed in a single step.  Obviously, you need to have a working VirtueMart shop on your site.
