/**
* 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()}.
