Empty Junit reports from ant - 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 ?
This is my build.xml :
<project name="JunitTest" default="test" basedir=".">
<property name="testdir" location="." />
<property name="srcdir" location="." />
<property name="full-compile" value="true" />
<property name="test.reports" value="./reports" />
<path id="classpath.base"/>
<path id="classpath.test">
<pathelement location="${testdir}" />
<pathelement location="${srcdir}" />
<path refid="classpath.base" />
</path>
<target name="clean" >
<delete verbose="${full-compile}">
<fileset dir="${testdir}" includes="**/*.class" />
</delete> `
</target>
<target name="compile" depends="clean">
<javac srcdir="${srcdir}" destdir="${testdir}" verbose="${full-compile}" >
<classpath refid="classpath.test"/>
</javac>
</target>
<target name="test" depends="compile">
<junit>
<classpath refid="classpath.test" />
<formatter type="brief" usefile="false" />
<test name="com.tests.nav1" />
</junit>
<junitreport todir="${test.reports}">
<fileset dir="${test.reports}">
<include name="TEST-*.xml" />
</fileset>
<report todir="${test.reports}" />
</junitreport>
</target>
</project>
and this is the output on the console :

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>

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

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.

Please try formatter with "xml"
<formatter type="${junit.format}"/>
where junit.format is property with appropriate value.
