[FIXED JENKINS-30522] Test results analyser should support workflow

Compare: https://github.com/jenkinsci/test-results-analyzer-plugin/compare/50ee9c49ce4e...40c6fe31e667

How do you use the test results plugin in the pipeline? Maybe I'm misunderstanding the issue because it doesn't seem fixed. I do not see it in the snippet generator and using the step command does not work for either the action or extension class. I must be missing something. Any help?

I tried adding the following to my Jenkins Pipeline - "step $class:'org.jenkinsci.plugins.testresultsanalyzer.TestResultsAnalyzerExtension'".

Maybe I'm missing something, but I'm getting the error below. I'm not sure I understand how the last commit did anything to integrate the Test Results plugin with the Pipeline plugin.

cjmead IIUC there is nothing to add to your script. The existing plugin functionality should just start working.

Using Jenkins 2.102 and Test Results Analyzer Plugin 0.3.4 I see exactly the same error as https://issues.jenkins-ci.org/browse/JENKINS-30522?focusedCommentId=266438&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-266438

Use the junit pipeline step.  It'll configure the job automatically to use the test results analyzer and as long as you have valid test results, will show the analyzer appropriately.
