Accerciser lets you test all aspects of accessibility on the GNOME desktop. It uses AT-SPI to inspect and control widgets, allowing you to check whether an application is providing correct information to assistive technologies and automated test frameworks. It has a simple plugin framework that you can use to extend and customize the accessibility information displayed. It is written in Python and uses the pyLinAcc component from LSR to interact with AT-SPI using pyORBit. In essence, it is a next generation at-poke tool.
