public class JUnitTask
extends Task
```
Runs JUnit tests.
JUnit is a framework to create unit tests. It has been initially created by Erich Gamma and Kent Beck. JUnit can be found at http://www.junit.org.
JUnitTask can run a single specific JUnitTest using the test element.
For example, the following target
```
   <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>
 
```
runs a single junit test (org.apache.ecs.InternationalCharTest) in the current VM using the path with id classpath as classpath and presents the results formatted using the standard plain formatter on the command line.

This task can also run batches of tests. The batchtest element creates a BatchTest based on a fileset. This allows, for example, all classes found in directory to be run as testcases.

For example,
```
 <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>
 
```
this target finds any classes with a test directory anywhere in their path (under the top ${tests.dir}, of course) and creates JUnitTest's for each one.

Of course, <junit> and <batch> elements can be combined for more complex tests. For an example, see the ant build.xml target run-tests (the second example is an edited version).

To spawn a new Java VM to prevent interferences between different testcases, you need to enable fork. A number of attributes and elements allow you to set up how this JVM runs.
Since:

Ant 1.2

  - setForkMode
```
public void setForkMode(JUnitTask.ForkMode mode)
```
    Set the behavior when fork fork has been enabled.
    Possible values are "once", "perTest" and "perBatch". If set to "once", only a single Java VM will be forked for all tests, with "perTest" (the default) each test will run in a fresh Java VM and "perBatch" will run all tests from the same <batchtest> in the same Java VM.
    
    This attribute will be ignored if tests run in the same VM as Ant.
    
    Only tests with the same configuration of haltonerror, haltonfailure, errorproperty, failureproperty and filtertrace can share a forked Java VM, so even if you set the value to "once", Ant may need to fork multiple VMs.
