Grails unit test verify mock method called

问题

In my unit test, I mock a service (which is a ref of the class under test).

Like:

given:
def mockXxService = mockFor(XxService)
mockXxService.demand.xxx(1) {->}
service.xxService = mockXxService
when:
service.yyy()
then:
// verify mockXxService's xxx method is invoked.

For my unit test, I want to verify that mockXxService.xxx() is called. But grails document's mockControl.verify() doesn't work for me. Not sure how to use it correctly.

It is very similar to mockito's verify method.

Anyone knows it?

You are using spock for your unit test, you should be easily able to use spock's MockingApi check invocations:

given:
    def mockXxService = Mock(XxService)
    service.xxService = mockXxService
when:
    service.yyy()
then:
    1 * mockXxService.xxx(_) //assert xxx() is called once

You could get more insight about mocking from spockframework docs.

You can even stub and mock that while mocking the concerned service as:

def mockXxService = Mock(XxService) {
    1 * xxx(_)
}

If you want Mockito-like behavior in Grails unit tests - just use Mockito. It is far more convenient than Grails' mocking methods.
