MissingMethodException in unit test with HibernateTestMixin when using dynamic finder after upgrade to Grails 3.0.6

Question

After upgrading a Grails 2.5.1 application to Grails 3.0.6 I am having troubles to get my unit tests working again.

I have a very simple domain class called Team.

class Team {

   String name
   String shortName
   String image = 'noimage.jpg'

   static constraints = {
       name nullable: false, maxSize: 30, unique: true
       shortName nullable: true, maxSize: 5
       image nullable: false, maxSize: 30
   }
}

and a unit test that does this

@TestMixin(HibernateTestMixin)
@Domain([Team])
class TeamSpec extends Specification {

    def setup() {
        new Team(name: 'Hello', shortName: 'Big').save()
    }

    def cleanup() {
    }

    void "test something"() {
        expect:"fix me"
            !Team.findByName('hello')
    }
}

When I execute the unit test I get the following runtime error

groovy.lang.MissingMethodException: No signature of method: static abc.Team.findByName() is applicable for argument types: (java.lang.String) values: [hello]
at abc.TeamSpec.test something(TeamSpec.groovy:24)

It complains about a dynamic finder that was available in Grails 2.5.x. Can anyone help me to solve that problem? Anyone had such a thing before?

EDIT

I created a plain new Grails 3.0.6 and generated a domain class by the task create-domain-class. Then I added the three String attributes (name, shortName, image) to the class and wrote a simple assertion !Team.findByName('A') but the exception remains.

EDIT 2 I still have no clue what I am doing wrong. I reported that issue to the Grails-Core issue tracker. Example code can be found here

EDIT 3 @TestFor does the job but I would like to work with the HibernateTestMixin instead of DomainClassUnitTestMixin in favour of a H2 in memory database. Therefore I added

testCompile 'org.grails:grails-datastore-test-support:4.0.5.RELEASE'

to my build.gradle. But when I add the HibernateTestMixin I get the following exception.

Answer 1

The behaviour is officially a bug that will be fixed by the release of Grails 3.0.8
