Test2::Harness::Renderer::JUnit - Captures Test2::Harness results and emits a junit xml file.


On the command line, with yath:

JUNIT_TEST_FILE="/tmp/test-output.xml" ALLOW_PASSING_TODOS=1 yath test --renderer=Formatter --renderer=JUnit -j4 t/*.t


Test2::Harness::Renderer::JUnit provides JUnit output formatting sufficient to be parsed by Jenkins and hopefully other junit parsers.

This code borrows many ideas from TAP::Formatter::JUnit but unlike that module does not provide a method to emit a different xml file for every testcase. Instead, it defaults to emitting to a single junit.xml to whatever the directory was you were in when you ran yath. This can be overridden by setting the JUNIT_TEST_FILE environment variable

Timing information is included in the JUnit XML since this is native to Test2::Harness

In standard use, "passing TODOs" are treated as failure conditions (and are reported as such in the generated JUnit). If you wish to treat these as a "pass" and not a "fail" condition, setting ALLOW_PASSING_TODOS=1 in your environment will turn these into pass conditions.

The JUnit output generated was developed to be used by Jenkins ( That's the build tool we use at the moment and needed to be able to generate JUnit output for.


  • render_event($event)

    This is the only method (other than finish) that is called by Test2::Harness in order to gather the data needed to emit the needed xml.

  • close_open_failure_testcase($test, $new_test_number)

    This method is called whenever a new test result or the end of a run is seen. Because we want to capture test diag messages after a failed test, we delay emitting a failure until we see the end of the testcase or until we see a new test number.

  • finish()

    This method is called by Test2::Harness when all runs are complete. It takes what has been gathered to that point and creates the junit xml file.

  • xml

    An XML::Generator instance, to be used to generate XML output.

  • init

    This subroutine is called during object initialization for Test2::Hanress objects. We do basic setup here.
