/**
* Runs JUnit tests.
*
* <p> JUnit is a framework to create unit tests. It has been initially
* created by Erich Gamma and Kent Beck. JUnit can be found at <a
* href="http://www.junit.org">http://www.junit.org</a>.
*
* <p> <code>JUnitTask</code> can run a single specific
* <code>JUnitTest</code> using the <code>test</code> element.</p>
* For example, the following target <code><pre>
* <target name="test-int-chars" depends="jar-test">
* <echo message="testing international characters"/>
* <junit printsummary="no" haltonfailure="yes" fork="false">
* <classpath refid="classpath"/>
* <formatter type="plain" usefile="false" />
* <test name="org.apache.ecs.InternationalCharTest" />
* </junit>
* </target>
* </pre></code>
* <p>runs a single junit test
* (<code>org.apache.ecs.InternationalCharTest</code>) in the current
* VM using the path with id <code>classpath</code> as classpath and
* presents the results formatted using the standard
* <code>plain</code> formatter on the command line.</p>
*
* <p> This task can also run batches of tests. The
* <code>batchtest</code> element creates a <code>BatchTest</code>
* based on a fileset. This allows, for example, all classes found in
* directory to be run as testcases.</p>
*
* <p>For example,</p><code><pre>
* <target name="run-tests" depends="dump-info,compile-tests" if="junit.present">
* <junit printsummary="no" haltonfailure="yes" fork="${junit.fork}">
* <jvmarg value="-classic"/>
* <classpath refid="tests-classpath"/>
* <sysproperty key="build.tests" value="${build.tests}"/>
* <formatter type="brief" usefile="false" />
* <batchtest>
* <fileset dir="${tests.dir}">
* <include name="**/*Test*" />
* </fileset>
* </batchtest>
* </junit>
* </target>
* </pre></code>
* <p>this target finds any classes with a <code>test</code> directory
* anywhere in their path (under the top <code>${tests.dir}</code>, of
* course) and creates <code>JUnitTest</code>'s for each one.</p>
*
* <p> Of course, <code><junit></code> and
* <code><batch></code> elements can be combined for more
* complex tests. For an example, see the ant <code>build.xml</code>
* target <code>run-tests</code> (the second example is an edited
* version).</p>
*
* <p> To spawn a new Java VM to prevent interferences between
* different testcases, you need to enable <code>fork</code>. A
* number of attributes and elements allow you to set up how this JVM
* runs.
*
