emma - no runtime coverage data found

Question

I can't define why emma isn't generating the runtime coverage data.

What I'm forgetting when running the tests? based on the this post: How to change Ant script with EMMA code-coverage so it can find runtime coverage data?

I put the instrumented classes in the top of the classpath

ant-emma.xml:

Answer 1

You get this error when you use wrong command to generate the report. Most of the online tutorial is advocating the wrong(may by old) command, even I got this error when I used below command to generate the report:

{JAVA_HOME}\jre\lib\ext>java -cp emma.jar emma report -r html -in coverage.em, {ALFRESCO_HOME}\coverage.ec 
EMMA: processing input files ... 
EMMA: 1 file(s) read and merged in 60 ms 
EMMA: nothing to do: no runtime coverage data found in any of the data files

Correct usage of the command is(Mark there is extra "-in" in command):

{JAVA_HOME}\jre\lib\ext>java -cp emma.jar emma report -r txt,html -in {JAVA_HOME}\jre\lib\ext\coverage.em -in C:\t1_tempSetup\Alfresco\coverage.ec 
EMMA: processing input files ... 
EMMA: 2 file(s) read and merged in 70 ms EMMA: writing [txt] report to [{JAVA_HOME}\jre\lib\ext\coverage.txt] ... 
EMMA: writing [html] report to [{JAVA_HOME}\jre\lib\ext\coverage\index.html]

Answer 2

The first time that I ran this, this error was occurring::

    [junit] Running app.commons.enums.TypeFileSizeTest

    [junit]     0000020:   

Actually I made a very bad supposition that I was doing it in the wrong way...

After a few days thinking and wasting some time to understand the problem.. I found the solution: add an argument in the VM: (Sorry I lost the reference..)

<jvmarg value="-XX:-UseSplitVerifier" />

-In the end I just need to modify my 'emma-do-test' task:

<target name="emma-do-test" depends="emma-instrumentation" >
    <junit printsummary="withOutAndErr" haltonfailure="true" fork="true"  >
        <classpath>
            <path refid="classpath.emma.run" />
        </classpath>
        <formatter type="plain" usefile="false" />
        <batchtest todir="${emma.report.dir}" >
            <fileset dir="${test.src.dir}" includes="**/*Test.java" />
        </batchtest>
        <jvmarg value="-XX:-UseSplitVerifier" />
        <jvmarg value="-Demma.coverage.out.file=${emma.runtime.coverage.data.file}" />
        <jvmarg value="-Demma.coverage.out.merge=false" />
    </junit>
    <echo message="Emma Test Result : ${emma.report.dir}" />
    <echo message="Emma file : ${emma.runtime.coverage.data.file}" />
</target>
