You must add the compiled classes to the class path of the junit task.
<junit fork="yes" haltonfailure="no" printsummary="yes" >
<classpath>
<path refid="testcase.path">
<pathelement location="${test.dest}"/>
</classpath>
<batchtest todir="${test.reportsDir}" fork="true">
<fileset dir="${test.dest}">
<include name="anttestcase/Login.class"/>
</fileset>
</batchtest>
<formatter type="xml"/>
</junit>
On Github there's an example ant project, which uses JUnit: https://github.com/mplacona/java-junit-template-project Have a look at it's build.xml.
