This test does too much.  Point geometry is already tested in the above 2 specs, there's no need to test it again.  There's also no reason to have a styleUrl, because it bloats the KML.  What you should have is a single placemark with an inline LabelStyle.  The style should have ALL of the possible options for a KML label and then you should check against the ones you currently handle.  Also, extract the repeated calls to `dataSource.getDynamicObjectCollection().getObjects()` into a variable because it makes the code easier to read.
