Revamped Tests UI in Jenkins

The JUnit plugin has received a major redesign, focusing on a cleaner and more consistent UI. This work draws directly from the Pipeline Graph View plugin and the Jenkins Design Library, bringing much-needed polish to one of Jenkins' oldest plugins.
So what’s new?
New user interface
The plugin has been redesigned to make test results easier to understand at a glance. Pages have been streamlined, components simplified and standardized, and the overall experience given a major cleanup.
Test names are split more intuitively, based on method, class, and package. This makes scanning large test suites easier.
Stacktraces are now also syntax-highlighted for better readability, and they can now be copied with a single click.
Responsive
The interface now scales from the largest screen to the smallest, so you can check results even on the go.
Moments of joy
When all of your tests pass, enjoy celebratory confetti. Because we know the satisfaction of watching a suite go green after a stubborn failure.
Available now 🚀
The update is available now for users on Jenkins 2.504.3 and later.
See it in action in the Jenkins core build on ci.jenkins.io.
