----------------------------------------

             Summary: maven-surefire-plugin with reuseForks=false doesn't find any tests in JUnit Jupiter 5.3.0
                 Key: SUREFIRE-1566
                 URL: https://issues.apache.org/jira/browse/SUREFIRE-1566
             Project: Maven Surefire
          Issue Type: Bug
          Components: JUnit 5.x support, Maven Surefire Plugin, process forking
    Affects Versions: 2.22.0
            Reporter: Allon Mureinik
         Attachments: reuser-forks.zip

This issue was originally reported against JUnit (see [https://github.com/junit-team/junit5/issues/1579|https://github.com/junit-team/junit5/issues/1579)] ). [Christian Stein|https://github.com/sormuras] noted that all the code for the integration resides in the Surefire repo, closed the original issue and requested one be reported here.
He also noted that [https://github.com/apache/maven-surefire/pull/193|https://github.com/apache/maven-surefire/pull/193,] , intended to solve SUREFIRE-1564 may fix the problem. Reading through the issue description this doesn't look like an exact duplicate, so I'm reporting the original issue here too - if the same fix addresses both that's great, but just wanted to have this problem on your radar.

 

When using a combination of JUnit 5.3.0 together with maven-surefire-plugin 2.22.0 configured with {{reuseForks=false}}, surefire fails to find any JUnit tests.

Downgrading JUnit to 5.2.0 makes it work (i.e., tests are properly found), as does setting {{reuseForks=true}}.

A complete example is available in the attached zip file. just unzip and run {{mvn install.}}

 

With JUnit 5.3.0, you'll see the output:

{{Tests run: 0, Failures: 0, Errors: 0, Skipped: 0 }}{{}}

With JUnit 5.2.0, you'll see the expected output:

{{Tests run: 1, Failures: 0, Errors: 0, Skipped: 0}}{{}}
