/**
 * Unit test template for use in submission of bugs.
 * <p>
 * This test case will delegate to an underlying backing store. You can specify
 * this store via a JVM property as follows:
 * <code>-DtestClass=com.bigdata.rdf.sail.TestBigdataSailWithQuads</code>
 * <p>
 * There are three possible configurations for the testClass:
 * <ul>
 * <li>com.bigdata.rdf.sail.TestBigdataSailWithQuads (quads mode)</li>
 * <li>com.bigdata.rdf.sail.TestBigdataSailWithoutSids (triples mode)</li>
 * <li>com.bigdata.rdf.sail.TestBigdataSailWithSids (SIDs mode)</li>
 * </ul>
 * <p>
 * The default for triples and SIDs mode is for inference with truth maintenance
 * to be on. If you would like to turn off inference, make sure to do so in
 * {@link #getProperties()}.
