Can Spock spy for real object?

Question

I wanna spy method calls of Spring bean. I checked docs - Spock can create spy only by constructor. Can Spock wrap already existing object by spy?

Answer 1

It seems that it can't be done because of the fact that API doesn't support it. Have a look at API. The following piece of code runs with errors:

@Grab('org.spockframework:spock-core:0.7-groovy-2.0')
@Grab('cglib:cglib-nodep:3.1')

import spock.lang.*

class Test extends Specification {
    def 'test'() {
        given:    
        def o = new Object()
        def s = Spy(o)
    }
}
