I'm migrating from Netbeans to setup all of my compiling, packaging
and testing. However, I'm having troubles getting the testing part
working. Here's the snippet of code I'm currently using:

<property name="src" value="src"/>
<property name="lib" value="lib"/>
<property name="build" value="build"/>
<property name="dist" value="dist"/>
<property name="dist-lib" value="${dist}/lib"/>
<property name="src.lib.runtime" value="${lib}/runtime"/>
<property name="classes" value="${build}/classes/"/>
<property name="jar.executable" value="${dist}/$
{ant.project.name}.jar"/>
<property name="test.src" value="test"/>
<property name="test.execute" value="${build}/test"/>
<property name="test.reports" value="${test.execute}/reports"/>

<!-- Runs the JUnit Tests -->
<target name="test">
<mkdir dir="${test.reports}"/>
<copy todir="${test.execute}">
<fileset dir="${src}"/>
</copy>
<copy todir="${test.execute}">
<fileset dir="${test.src}"/>
</copy>
<javac srcdir="${test.execute}"
classpath="${classpath}"
debug="true"
source="1.5"
/>
<junit dir="${test.execute}">
<test name="tciworks.analysis.BayesianTest"/>
</junit>
<!--junit printsummary="yes">
<formatter type="plain"/>
<batchtest fork="yes" todir="${test.reports}">
<fileset dir="${test.execute}}">
<include name="**/*Test*.java"/>
</fileset>
</batchtest>
</junit-->
</target>

Code being tested is in ${src}
Test cases are in ${test.src}.
All of the source is copied to ${test.execute} and compiled there.

When I try to test I get the following (trimmed) error:

Very hard to say without having the code to play with.

You could try replace:

<junit dir="${test.execute}">

with:

<junit fork="on" dir="${test.execute}">

because I have often had problems without that.
