How can I generate an HTML report for Junit results?
If you could use Ant then you would just use the JUnitReport task as detailed here: http://ant.apache.org/manual/Tasks/junitreport.html, but you mentioned in your question that you're not supposed to use Ant. I believe that task merely transforms the XML report into HTML so it would be feasible to use any XSLT processor to generate a similar report.
Alternatively, you could switch to using TestNG ( http://testng.org/doc/index.html ) which is very similar to JUnit but has a default HTML report as well as several other cool features.
I found the above answers quite useful but not really general purpose, they all need some other major build system like Ant or Maven.
I wanted to generate a report in a simple one-shot command that I could call from anything (from a build, test or just myself) so I have created junit2html which can be found here: https://github.com/inorton/junit2html
You can install it by doing:
pip install junit2html
Alternatively for those using Maven build tool, there is a plugin called Surefire Report.
The report looks like this : Sample
You can easily do this via ant. Here is a build.xml file for doing this
<project name="genTestReport" default="gen" basedir=".">
<description>
Generate the HTML report from JUnit XML files
</description>
<target name="gen">
<property name="genReportDir" location="${basedir}/unitTestReports"/>
<delete dir="${genReportDir}"/>
<mkdir dir="${genReportDir}"/>
<junitreport todir="${basedir}/unitTestReports">
<fileset dir="${basedir}">
<include name="**/TEST-*.xml"/>
</fileset>
<report format="frames" todir="${genReportDir}/html"/>
</junitreport>
</target>
</project>
This will find files with the format TEST-*.xml and generate reports into a folder named unitTestReports.
To run this (assuming the above file is called buildTestReports.xml) run the following command in the terminal:
ant -buildfile buildTestReports.xml
