PeopleTools 8.51 has introduced a new and exciting feature:PeopleSoft Test Framework (from now on PTF). This tool can be used to automate testing of PeopleSoft applications. Unlike other testing automation tools, PTF has the following advantages:

• PTF is a testing automation tool designed to interact with PeopleSoft. It is quite easy to install and put it up to speed.
• Tests are stored in PeopleSoft database as metadata. This allows developers to migrate tests between environments, pretty much like any other PeopleTools object.
• Based on Usage Monitor, testers can determine which tests are impacted by a given application change: upgrade, bundle and/or customization.
