Empty Junit reports from ant

Question

I am trying to use ant to run junit tests and generate reports. I am able to successfully run the tests but the report files are empty.

What am I doing wrong ?

Answer 1

If you look at the ant snippet, there are a few issues:

• You have set usefile=false, which means no output file is created
• You have set formatter type=brief, which will print detailed information only for failed tests
• You need to also specify the todir - the folder where the report has to go in the <test> tag - the default is current folder. This should match the folder you are using in <junitreport> task.

You can try with the following updated <junit> section...

    <junit>
        <classpath refid="classpath.test" />
        <formatter type="xml"/>
        <test name="com.tests.nav1" todir="${test.reports}"/>
    </junit>

Answer 2

The ant JUnit Task doc gives this example that might help you (as it apparently does exactly what you're trying to achieve):

<junit printsummary="yes" haltonfailure="yes">
    <classpath>
        <pathelement location="${build.tests}"/>
        <pathelement path="${java.class.path}"/>
    </classpath>

    <formatter type="plain"/>

    <test name="my.test.TestCase" haltonfailure="no" outfile="result">
        <formatter type="xml"/>
    </test>

    <batchtest fork="yes" todir="${reports.tests}">
        <fileset dir="${src.tests}">
            <include name="**/*Test*.java"/>
            <exclude name="**/AllTests.java"/>
        </fileset>
    </batchtest>
</junit>

Runs my.test.TestCase in the same VM, ignoring the given CLASSPATH; only a warning is printed if this test fails. In addition to the plain text test results, for this test a XML result will be output to result.xml. Then, for each matching file in the directory defined for ${src.tests} a test is run in a separate VM. If a test fails, the build process is aborted. Results are collected in files named TEST-name.txt and written to ${reports.tests}.

It is specified in the doc that printsummary can take values on and off, but they're using yes in the example which is on the same page, so I guess it's accepted too.

Answer 3

Please try formatter with "xml"

   <formatter type="${junit.format}"/>

where junit.format is property with appropriate value.

Answer 4

   1 <target name="test" depends="compile">
   2     <junit>
   3         <classpath refid="classpath.test" />
   4         <formatter type="brief" usefile="false" />
   5         <test name="com.tests.nav1" />
   6     </junit>

   7     <junitreport todir="${test.reports}">
   8         <fileset dir="${test.reports}">
   9             <include name="TEST-*.xml" />
   10         </fileset>
   11         <report todir="${test.reports}" />
   12     </junitreport>
   13 </target>

The above segment of your coded needs following changes.

1. You have to specify the to directory option in the 5th line( for example todir = ${data.reports} )
2. In the 8th line the directory specified must me data.reports.
3. The 11th line must contain the option format with the value frames (format="frames").
