Overview of GUI Testing

GUI is the abbreviation for Graphic User Interface. It is absolutely essential that any application has to be user-friendly. The end user should be comfortable while using all the components on screen and the components should also perform their functionality with utmost clarity. Hence it becomes very essential to test the GUI components of any application. GUI Testing can refer to just ensuring that the look-and-feel of the application is acceptable to the user, or it can refer to testing the functionality of each and every component involved.

The following is a set of guidelines to ensure effective GUI Testing and can be used even as a checklist while testing a product / application.
