How to compare test results of a Gradle build

I'm currently using build artifact comparison tools / plugins available in Gradle like compare-gradle-builds (http://ift.tt/1J5XAXo in Gradle) or Artifact Diff Plugin (in Jenkins) or using some utility program(s) like pkgdiff (I would say this is one of the easiest way to see high level / detailed low level differences while doing artifact comparisons with nice HTML report output).

This helps in showing what's happened / changed since last build or in two given builds.

Similarly, I'm trying to find if there are any tools/utilities/plugins available online (in Gradle, Jenkins or other open source tool) which I can use to compare the test results (Unit / or non-unit tests like Integration / etc) of two given builds (i.e. it'll show me what exactly got added/removed/changed/failed/turned successful/time took to run the tests/configuration changes in the tests or in the test code etc with side by side comparison if possible?

I know SonarQube provides info about this to some extent (since previous analysis/in last X no. of days periods etc) but I'm wondering if there are specific tools/plugins/utilities available just for doing comparison on test results.

NOTE:
What if I'm running:
1. Tests in IE (Internet Explorer) in one matrix configuration slave/job and tests in FF(Firefox) in other. 2. What if there are multiple jobs (for running suite of tests). Is there any way to aggregate the results and compare.

Thanks.
