Jameleon is an automated testing framework that can be easily used by technical and non-technical users alike. One of the main concepts behind Jameleon is to create a group of keywords or tags that represent different screens of an application. All of the logic required to automate each particular screen can be defined in Java and mapped to these keywords. The keywords can then be organized with different data sets to form test scripts without requiring an in-depth knowledge of how the application works. The test scripts are then used to automate testing and to generate manual test case documentation.

Jameleon was designed to test many kinds of applications. To make this possible, Jameleon was designed with a plug-in model. Currently, there are five plug-ins offered:

A JUnit plug-in which can be used to test at a white box level. All JUnit function tags can be used in conjunction with other plug-ins.
A Jiffie plug-in which drives Internet Explorer and can therefore only be run on Windows. Most testers like this plug-in the most.
An HtmlUnit plug-in which emulates a browser and supports JavaScript quite well. Because it emulates a browser, tests written in this plug-in can execute on any OS supported by Java.
A Selenium Plug-in which drives the most popular browsers. tests written in this plug-in can execute on the most popular OSes.
An HttpUnit plug-in which emulates a browser, but doesn't have very good JavaScript support. Developers like this plug-in the most. Because it emulates a browser, tests written in this plug-in can execute on any OS supported by Java.
A 3270 (Jagacy) plug-in which is used to automate mainframe applications.
A jWebUnit plug-in which is the most basic among the provided plug-ins and currently has no generic tags other than a session tag.
