Sam Hasler's answer only works for freestyle Jenkins jobs. We use Maven jobs and this configuration option of the JUnit Jenkins plugin is unavailable for Maven jobs. So I was looking for a more universal solution.
What we did in order to get it working is to reconfigure the Jasmine Maven plugin so as to
- no longer halt the build upon test failures and
- write the Jasmine test reports to target/surefire-reports where Jenkins expects to find them. This has the additional advantage that we now also see the failed Jasmine test in the build job alongside our Java tests.
<haltOnFailure>false</haltOnFailure>
<jasmineTargetDir>${project.build.directory}/surefire-reports</jasmineTargetDir>
Now our build jobs are yellow (unstable) as expected, no longer red (failed).
