Call a method on the target class when using own @TestMixin

[David Molinero]

Hi,
I have a code like this that works right with groovy mixins:

import spock.lang.Specification

// FIRST EXAMPLE - The test passes

@Category(GroovyObject)
class AGroovyMixin {

    def methodInTheMixinThatInvokesAMethodOfTheSpec() {
        println 'the method in the mixin is called'
        aMethodOfTheSpecInvokedInAMixin()
    }
}

@Mixin(AGroovyMixin)
class FirstSpec extends Specification {

    def invocations = 0

    def aMethodOfTheSpecInvokedInAMixin() {
        invocations++
    }

    def 'check that that a method of this spec has been called in the mixin'() {
        when:
        methodInTheMixinThatInvokesAMethodOfTheSpec()

        then:
        invocations > 0
    }
}

but when I use '@Mock' or '@TestMixin' in my FirstSpec, my own groovy mixin (AGroovyMixin) stop work.

If I change the code to use a @TestMixin implementation, the test fails.

import spock.lang.Specification
import grails.test.mixin.TestMixin

// SECOND EXAMPLE - The test fails

class AGrailsTestMixin {

    def methodInTheMixinThatInvokesAMethodOfTheSpec() {
        println 'the method in the mixin is called'
        aMethodOfTheSpecInvokedInAMixin()
    }
}

@TestMixin(AGrailsTestMixin)
class SecondSpec extends Specification {

    def invocations = 0

    def aMethodOfTheSpecInvokedInAMixin() {
        invocations++
    }

    def 'check that that a method of this spec has been called in the test mixin'() {
        when:
        methodInTheMixinThatInvokesAMethodOfTheSpec()

        then:
        invocations > 0
    }
}

I would like to combine the use of @Mixin with @Mock, or have an implementation of @TestMixin that can access to methods on the target class. What could I do?

Thanks.

David.
