TestLeft supports testing of various XUL controls.
About Supported XUL Controls
TestLeft provides extended support for the most popular user interface controls created via Mozilla’s XML User Interface Language (XUL). In your tests, you can identify these controls and cast them to appropriate interfaces that extend the controls’ functionality with a number of supplementary methods and properties. Use these properties and methods to various operations over web elements and controls, for example, select individual items or retrieve the item text (see below).
