JUnit PDF Report creates PDF reports from your JUnit test results.
If you have an Ant script that generates HTML reports, you can plug in a task with the same settings as the standard JUnitReport.
You can download the example PDF report generated by JUnit PDF Report.
The project provides different themes to format the test report.
If you already have a build script that generates JUnit HTML reports, you can just plug in a junitpdfreport target with the same settings as your junitreport target.
You only have to follow a few simple steps.
