No signature of method: save() is applicable for argument types: () values: []

We are trying to upgrade a existing Grails 1.x application from 1.x to 2.x (current using 2.2.1). One unit test is failing and I am stuck. Here is what the test is doing...

Service -

def saveSomeData(myDomain) {
    return myDomain.save(flush:true)
}

Service Test -

void testShouldSaveAndReturnTrue() {
    def myDomainEmc = new ExpandoMetaClass(MyDomain)
    myDomainEmc.save = {flush -> true}
    myDomainEmc.initialize()
    myDomainEmc.metaClass = myDomainEmc
    assertTrue myTestService.saveSomeData(myDomainEmc)
}

From the error message, it looks like save() is being called somewhere without any arguments. Try adding a no-arg save() method:

myDomainEmc.save = {-> true}

Also, I'd recommend using the Grails 2 @Mock annotation for mocking domain objects to save having to handle all the possible method calls with an ExpandoMetaClass.
