dogtail only works with specific accessibility settings

[maweki]

According to the docs (and also via testing), dogtail needs certain accessibility settings to be run.

Currently GNOME and GTK+ applications are supported. Thanks to qt-at-spi KDE4 and QT applications are now available too.

First, enable accessibility support in your GNOME session with: gsettings set org.gnome.desktop.interface toolkit-accessibility true This only affects newly-started applications, so you may want to log out and log back in again.

If you are using KDE instead, install the 'qt-at-spi' QT plugin and make sure you QT_ACCESSIBILITY set to 1 throughout your environment (you can put 'export QT_ACCESSIBILITY=1' to your profile file). QT accessibility should be stable from QT 4.8.3 onward.

If this isn't the case, nosetests just fails silently. This also means, testing these parts is not supported on windows.

We could:

• set/reset this stuff in the setUp and tearDown methods in those classes.
• force it onto the users when they want to run tests.
• create a test-runner bash-script
