 * JUnit test that exports the demos.
 *
 * <p>To run these tests, use:
 * <pre>
 * cd $PTII
 * ./configure
 * ant test.single -Dtest.name=ptolemy.vergil.basic.export.test.junit.ExportModelJUnitTest -Djunit.formatter=plain
 * </pre>
 * or
 * <pre>
 * cd $PTII/ptolemy/vergil/basic/export/test/junit/;
 * export CLASSPATH=${PTII}:${PTII}/lib/junit-4.8.2.jar:${PTII}/lib/JUnitParams-0.3.0.jar${PTII}:${PTII}/lib/junit-4.8.2.jar:${PTII}/lib/JUnitParams-0.3.0.jar;
 * export JAVAFLAGS="-Dptolemy.ptII.exportHTML.linkToJNLP=true -Dptolemy.ptII.exportHTML.usePtWebsite=true"
 * $PTII/bin/ptinvoke org.junit.runner.JUnitCore ptolemy.vergil.basic.export.test.junit.ExportModelJUnitTest
 * </pre>
 * <p>Or, if you want to debug this to find leaks, try removing most of the models from $PTII/ptolemy/configs/doc/models.txt
 * and then running the above exports followed by $PTII/bin/ptjacl and then:
 * <pre>
 * set cmdArgs [java::new {java.lang.String[]} 1 {ptolemy.vergil.basic.export.test.junit.ExportModelJUnitTest}]
 * java::call org.junit.runner.JUnitCore main $cmdArgs
 * </pre>
 * <p>Then a few models will export and leaks can be checked.</p>
 * <p>
