There are currently no unit tests of any of the public methods in the java classes inside the mil.nga.giat.geowave.adapter.raster.adapter package. SourceThresholdMosaicDescriptor and SourceFixThresholdMosaicDescriptor can be ignored in this package as they are very specific to fixing a bug in a third-party library and other classes can be lightly touched, but primarily, RasterDataAdapter does a lot of important work for GeoWave’s ability to read and write rasters to and from key-value stores.
