Re: [Cobertura-devel] Instrument task misses classes, tests die as a result

[Bill H. <han...@mc...>]

Jake,

I’ve tried it both ways.

Classpath for test exec:
…
/var/cruise/hudson/home/jobs/requestor-trunk/workspace/trunk/work/test:
/var/cruise/hudson/home/jobs/requestor-trunk/workspace/trunk/test:
/var/cruise/hudson/home/jobs/requestor-trunk/workspace/trunk/work/test/instrumented:

If the if the instrumented version is first or second, cobertura runs and all test coverage shows 0%.

Thanks,
Bill Hansley

When you included both directories on the classpath, did you have the non-instrumented folder come first?  If so, try putting the instrumented dir first so any classes present in both will load the instrumented version.

Hi,

I’m a newbie to Cobertura, and am having trouble getting it to work completely from start to finish.

Starting from the end, here’s the error I’m getting:


java.lang.reflect.InvocationTargetException
Caused by: java.lang.NoClassDefFoundError: edu/duke/dhts/periop/requestOR/persistence/broker/PersistenceBroker$PerformWithHibernateSession
        at java.lang.ClassLoader.defineClass1(Native Method)
        at java.lang.ClassLoader.defineClass(ClassLoader.java:621)

        at java.lang.ClassLoader.loadClass(ClassLoader.java:252)
        at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320)


The class it can’t find (PersistenceBroker$PerformWithHibernateSession) is in my classes directory, but when instrument runs via ant, using this task:


                <target name="cobertura-tag-classes">
                                <delete file="cobertura.ser" />
                                <cobertura-instrument todir="${classes.instrumented}">
                                                <ignore regex="org.apache.log4j.*" />
                                                <fileset dir="${classes}">
                                                                <include name="**/*.class" />
                                                </fileset>
                                </cobertura-instrument>
                </target>

The log file says it runs successfully:


cobertura-tag-classes:

   [delete] Deleting: /var/cruise/hudson/home/jobs/requestor-trunk/workspace/trunk/cobertura.ser

[cobertura-instrument] Cobertura: Saved information on 187 classes.

[cobertura-instrument] Instrument time: 1982ms



Yet, when I go to execute my tests, I get this:

java.lang.reflect.InvocationTargetException
Caused by: java.lang.NoClassDefFoundError: edu/duke/dhts/periop/requestOR/persistence/broker/PersistenceBroker$PerformWithHibernateSession
        at java.lang.ClassLoader.defineClass1(Native Method)

        at suite.edu.duke.dhts.periop.requestOR.AllTests.suite(AllTests.java:19)

        at java.lang.ClassLoader.loadClass(ClassLoader.java:252)
        at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320)


PersistenceBroker$PerformWithHibernateSession is in my original classes directory, but not in the instrumented classes directory.

I can get Cobertura to run to completion by including my non-instrumented classes in the test run path, but everything comes up 0%. If I remove my non-instrumented classes, it dies trying to run the test with the exception above.

Setup:
Java: 1.6.0_14-b08
Cobertura: 1.9.4.1
Ant: 1.7.1
Hudson: 1.363

Any advice?

Thanks,
Bill Hansley
