protected java.util.MapinitializedGenericTagTestProperties()
Initialize a map of {@link PropertyHolder} for generic tag property testing. Will be used when calling {@link #verifyGenericProperties(org.apache.struts2.views.jsp.ui.AbstractUITag, String, String[])} as properties to verify.

This implementation defines testdata for all common AbstractUITag properties and may be overridden in subclasses.

return
A Map of PropertyHolders values bound to {@link org.apache.struts2.views.jsp.AbstractUITagTest.PropertyHolder#getName()} as key.

        new PropertyHolder("name", "someName").addToMap(result);
