Juint task in Ant

[Hongli Li]

Hi, folks,

I spent the whole afternoon trying to figure out why I couldn't run junit with ant, but unfortunately, it didn't work for me.Can somebody help me?

part of my build.xml:

  
        <property name="test.suite" value="first ant junit test"/>
<property name="build.classes" location="build/classes" />
<property name="build.test.classes" location="build/test/classes" />
<path id="compile.classpath">
<fileset dir="lib">
<include name="*.jar" />
</fileset>
</path>
<path id="test.compile.classpath">
<path refid="compile.classpath" />
<pathelement location="${build.classes}" />
</path>
<path id="test.classpath">
<path refid="test.compile.classpath" />
<pathelement location="${build.test.classes}" />
</path>
<target name="init">
<mkdir dir="${build.classes}" />
<mkdir dir="dist" />
</target>
<target name="compile" depends="init">
<javac destdir="${build.classes}" srcdir="src">
<classpath refid="compile.classpath" />
</javac>
</target>
<target name="test-init">
<delete dir="${build.test.classes}" />
<mkdir dir="${build.test.classes}" />
</target>
<target name="test-compile" depends="compile,test-init">
<javac destdir="${build.test.classes}" debug="true" includeAntRuntime="false" srcdir="test">
<classpath refid="test.compile.classpath" />
</javac>
</target>
 <target name="junit" depends="test-compile" >
<junit printsummary="true" haltonfailure="true">
<classpath refid="test.classpath" />
<test name="${test.suite}" />
</junit>
</target> 

I'm sure the sequence of compiling test and source code is correct, I added the lib, src/classes, and test/classes to test.classpath which is defined in
path datatype. I test my code in Junit from Eclipse, it passed! When I tried to run it with ANT, then I always got this error:

here is the console output:

I also tried to run ant in eclipse, it didn't work in eclipse neither.
When I run "which ant" in my console, it displays /usr/bin/ant.
Anyone has any clue? Any suggestion is high appreciated.

Did you follow Ant's instructions You must have junit.jar available?

Try running ant with the -verbose option to get more details logged.

[Hongli Li]

thanks for you reply, Jan

yes, I did follow ant's instruction. junit-3.8.2.jar is under $ANT_HOME/lib folder, as you can see from the log, junit-3.8.2.jar is implicitly added to the classpath.

the following is what I got with -verbose mode.

java.lang.ClassNotFoundException: first ant junit test

'first ant junit test' is not a valid java class name. Your test class has to be a valid java class, say FirstAntJunitTest.

[Hongli Li]

thanks a lot Jan,
I overlooked at that line, My bad, I thought the test node inside Junit is just served as meta info, but actually it should be a full qualified class name.

cheers
