>                 Key: SUREFIRE-2144
>                 URL: https://issues.apache.org/jira/browse/SUREFIRE-2144
>             Project: Maven Surefire
>          Issue Type: Bug
>    Affects Versions: 2.22.2
>            Reporter: Geoff Soutter
>            Priority: Major
>
> My team is dynamically creating tests using the JUnit3 suite api, and running 
> this using Jenkins CI
> There is a nasty failure pattern which periodically deletes the Jenkins test 
> history - it resets the Age of all tests in Jenkins back to 1. The history / 
> Age report in Jenkins is key for us as it reveals which commit caused the 
> failure. We definitely do not want to lose that information.
> The failure pattern goes like this:
> * many tests are running fine, with some failures
> * a commit is made, CI triggers, Jenkins runs surefire.
> ** This results in a problem inside the suite() method, which throws a 
> RuntimeException. This is the dynamic test creation phase, before any tests 
> are run.
> ** This results in Surefire reporting a successful run of a single 
> "fake/synthetic" test which is reported as failed.
> * a commit is made to fix the test creation phase, CI again triggeers, 
> Jenkins runs surefire
> ** This results in many tests again running fine, with the same failures as 
> before
> ** However, Jenkins now reports all the old failures from the first step as 
> Age 1 - all the Age history is lost
> The synthetic test failure looks like so:
> {code}
> [ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 1.847 
> s <<< FAILURE! - in com.company.package.MySuite
> [ERROR] initializationError(com.company.package.MySuite)  Time elapsed: 0.046 
> s  <<< ERROR!
> {code}
> There is no "initializationError" test in our source code. I presume Surefire 
> has created it.
> It seems that the Jenkins JUnit report analysis gets completely confused when 
> it does the history analysis in this case. Presumably it tries to compare 
> * the "many" passing and failing tests from run N-1 with 
> * the single fake test from run N 
> After that I presume it decides that those many N-1 tests have been deleted, 
> and therefore deletes the history of those tests.
> So it seems that if we value the history analysis, we need to keep the test 
> names stable. If so, I suspect the fix is here is that Surefire should never 
> create and pretend to run synthetic tests. Rather, the entire run should 
> simply fail - I presume throw an exception out of the surefire plugin back to 
> maven? 
> Hopefully this would then prevent Jenkins from doing the test analysis and it 
> will not break the history / Age reporting.
