com.volantis.mcs.expression.functions.diselect.DIAspectRatioFunction
This Function retrieves the aspect ratio of the device from the repository If the repository contains no entry for aspect ratio then the supplied default value will be returned. If this default value is not valid, an empty string will be returned.
It is also the superclass of the aspect ratio width and height functions.

     * Return the {@link DIAspectRatioFunction} that should be used in tests.
     *
     * @return DIAspectRatioFunction to be used in tests.
