Ant JUnit Batchtest .java or .class

Question

I have seen a few links which appears to imply that JUnit tests can be executed from the .java file instead of the .class

For example

<junit printsummary="yes" haltonfailure="yes" haltonerror="yes">
        <classpath refid="ui.tests.classpath"/>
        <formatter type="xml"/>
        <batchtest todir="${env.WORKSPACE}/UITests/output">
            <fileset dir="${ui.tests.classes}">
                <include name="**/*Test.java"/>
            </fileset>
        </batchtest>
</junit>

Instead of

<junit printsummary="yes" haltonfailure="yes" haltonerror="yes">
        <classpath refid="ui.tests.classpath"/>
        <formatter type="xml"/>
        <batchtest todir="${env.WORKSPACE}/UITests/output">
            <fileset dir="${ui.tests.classes}">
                <include name="**/*Test.class"/>
            </fileset>
        </batchtest>
    </junit>

Is the first example a valid case? I could not get it working due to ClassNotFoundExceptions

I agree with the comment above, that it looks like the tag allows for either .java or .class.

I did a small test and when I ran a test with this setup - where the dir=somefolder, then using <include name="**/*Test.java"/> when the folder pointed at contains class files, then Ant will basically have an empty fileset to process for *Test.java, but when using <include name="**/*Test.class"/> then the fileset was not empty and the test cases will get run.

This was the result of my quick test. As far as I could tell, it looks like you need to specify the *Test.class to pickup the test cases.
