Show test results in the MR widget
Pipelines normally include a test job. If it fails, the pipeline fails, and developers can look into the job output log to find which is the test that is creating the problem.
We can help developers to speed up this process by showing job errors in the MR widget, in a similar way it is done for Code Quality and Security features. We can show the list of errors with links.
Since we are in the MR widget, we could consider to provide a diff between the feature branch and the
master branch like we do for other features, but in this case it could be tricky because we should not have failed tests on
master at all.
Implement a new panel in the MR widget to show failed tests (and fixed tests if we go for the diff approach).
test job should produce an artifact with results in a common format like JUnit.
This issue is strictly related with #17081. That issue is the related view at pipeline level.
