Script Runner - IntelliJ Test integration

Question

Hey,

i was following the following Guide for Testing:
Testing your Code

And stumbled into the following Error's while trying to get run the Test from the IDE.

2019-02-20 11:03:20,452 http-nio-8080-exec-7 ERROR admin 663x727x2 1y98v 127.0.0.1 /rest/scriptrunner/latest/canned/com.onresolve.scriptrunner.canned.common.admin.RunUnitTests [c.o.s.c.common.admin.RunUnitTests] *************** FAILED initializationError(org.junit.runner.manipulation.Filter) ********************

Thats my corresponding test class:

package de.mycompany.jira.example

import com.onresolve.scriptrunner.canned.common.admin.ScriptRunnerTestRunner
import org.junit.runner.RunWith
import spock.lang.Specification

@RunWith(ScriptRunnerTestRunner)
class TestRunnerSampleSpec extends Specification {

def "test something"() {
        expect:
true
    }
}

i suspect that i have to set the default package for the test, but i don't know where and how.

Moreover, there was already a similar question in the community, unfortunately no one could answer it.

That's why I link it again
