[Cobertura-devel] Cobertura shows zero code coverage despite all tests running.

[Jeevan C. <cha...@gm...>]

Hi,

I had a strange problem while running cobertura code coverage report on one
of my ant & junit based java project. The code coverage shows zero for all
packages despite the fact the unit tests are running fine.

Pasted below are the different tasks added to the ant build xml to get this
running:

*Classpath:*

        <path id="cobertura.classpath">
            <fileset dir="${cobertura.dir}">
                <include name="cobertura.jar" />
                <include name="lib/**/*.jar" />
            </fileset>
        </path>

        <taskdef classpathref="cobertura.classpath"
resource="tasks.properties"/>

*Instrument:*

        <property name="instrumented.dir" value="dist/instrumented-classes"
/>

        <target name="instrument" depends="init,compile">
                <delete file="cobertura.ser"/>
                <delete dir="${instrumented.dir}" />
                <cobertura-instrument todir="${instrumented.dir}"
datafile="cobertura.ser">
                <fileset dir="${dist.classes.dir}">
                        <include name="**/*.class"/>
                        <exclude name="**/*Test*"/>
                </fileset>
                </cobertura-instrument>
        </target>

Junit Test:

        <target name="module-test"
                depends="module-compile,module-test-postgresql">
                <echo level="info" message="Running JUnit test cases..." />
                <junit fork="yes" showoutput="yes" printsummary="yes"
reloading="false"
                        failureProperty="test.failed">

                        <jvmarg value="-enableassertions" />
                        <sysproperty
key="net.sourceforge.cobertura.datafile" file="cobertura.ser" />
                        <classpath location="${instrumented.dir}" />
                        <classpath location="${dist.classes.dir}" />
                        <classpath refid="cobertura.classpath" />
                        <formatter type="xml" />
                        <batchtest todir="${module.test.dir}">
                                <fileset refid="test.src.set" />
                        </batchtest>
                </junit>
         </target>

*Code coverage:*

         <target name="code-coverage">
               <cobertura-report format="html"
srcdir="${examinet.dir}/common/src" destdir="dist/cobertura-report"
datafile="cobertura.ser" />
        </target>

I have the run the following command which went fine but resulting a zero
code coverage.

*$ ant instrument module-test code-coverage*

Please help me with what went wrong with the above configuration that is
resulting in a zero code coverage across all packages.

Jeevan
