I wonder if there is something wrong with my ant junit task - ant

Question

I'm writing my build.xml. However, it seems there is something go wrong with my junit task. when I run my junit task. I can build success, but the junit report only show that run 1 test with error. But I have more than 10 tests. So I wonder if there is something run with my junit task. Here is my code.
<property name="src.dir" value="src"/>
<property name="bin.dir" value="bin"/>
<property name="dest.dir" value="dest"/>
<property name="test.dir" value="test/>
<property name="lib.dir" value="lib"/>
<path id="classpath">
<pathelement location="${lib.dir}/junit-4.11.jar"/>
<pathelement location="${lib.dir}/ant-junit4.jar"/>
</path>
<target name="test" depends="compile">
<junit printsummary="yes" haltonfailure="no">
<classpath>
<pathelement location="${bin.dir}"/>
<path refid="classpath"/>
</classpath>
<formatter type="plain" usefile="false"/>
<batchtest fork="yes">
<fileset dir="${test.dir}" includes="*Test*.java"/>
</batchtest>
</junit>
</target>
I cannot figure out what is wrong so could somebody help me out?

And what is happening? Do you get any error messages?
You usually need to do the following:
Compile your normal code. The resulting *.class files should be placed inside a directory such as target/classes or build/classes. Use the destdir parameter of the <javac> task to do this.
Compile your JUnit tests.
In your classpath, you need all of the jars you needed to compile your normal classes
You need a reference to the destdir where your normal classes were compiled to.
You need the JUnit jar.
These should be compiled to a different directory from your normal jars. Normally, this is target/test-classes or build/test-classes.
Once you've compiled the JUnit tests, you may run them. You can use the <junit> task like you did.
You need to make sure that the includeantruntime parameter is set to true
You should also set fork to true.
You need the same classpath (with all three elements you had) when you compiled the test classes. More jars might be needed, but usually not.
You run the tests on the compiled JUnit test classfiles (the ones you saved to target/test-classes or build/test-classes. In your example, you're trying to run them against the source.
I use the Maven standards for my directory layout. That means my Java source is under src/main/java while my JUnit Java files are under src/test/java. Any XML or properties or other none source files needed are stored in src/main/resources. The regular source is compiled to target/classes while the Junit sources are compiled to target/test-classes.
This makes it easy to compile your code and test code separately without worrying about **/test/**, **/Test/**, **/JUnit/** exceptions in directory compiling since everything is separate.
Hope this helps.
