        setUp() // I should not have to do this.  super.setup() in setup() should be enough
        // If i remove, I get error:  Helper is not initialized: Call setUp() before tests.
        File jenkinsfile = new File('test/resources/jenkinsfiles/Jenkinsfile')

        runScript(script)

Ok, yes, it's JUnit 5. I had no idea there was no @Before. That seems to explain the confusion.

I just tried and added:

    @BeforeEach
    void jpuJunit4Setup(){
        setUp()
    }

As a hacky workaround and now i don't need to call setUp() in all my tests anymore. Thanks!

cool, good to know!
