public abstract class BasePostingsFormatTestCase
extends LuceneTestCase

Abstract class to do basic tests for a postings format. NOTE: This test focuses on the postings (docs/freqs/positions/payloads/offsets) impl, not the terms dict. The [stretch] goal is for this test to be so thorough in testing a new PostingsFormat that if this test passes, then all Lucene/Solr tests should also pass. Ie, if there is some bug in a given PostingsFormat that this test fails to catch then this test needs to be improved!
