public abstract class BaseSegmentInfoFormatTestCase
extends LuceneTestCase

Abstract class to do basic tests for si format. NOTE: This test focuses on the si impl, nothing else. The [stretch] goal is for this test to be so thorough in testing a new si format that if this test passes, then all Lucene/Solr tests should also pass. Ie, if there is some bug in a given si Format that this test fails to catch then this test needs to be improved!
