Ant - Junit

In the build file

In the buildfile, just add to the classpath element the junit.jar.

Example:

<!-- Add the test jar (junit and testng) -->
<path id="test.class.path">
	<path refid="classpath.base" />
	<fileset dir="${test.lib}">
		<include name="**/junit*.jar" />
		<include name="**/*test*.jar" />
	</fileset>
</path>

<!-- Run the test and design the test.class.path -->
<target name="test" depends="create">
	<junit printsummary="true" haltonfailure="no">
		<classpath refid="test.class.path" />
		<formatter type="plain" usefile="false" />
		<test name="junit/HelloWorld" haltonfailure="no" outfile="junitout/HelloWorld" />
	</junit>
</target>

With eclipse

Add junit.jar in the configuration path.
