spock-mockable allows creation of mocks otherwise un-mockable by the Spock Framework.
Spock is not capable of mocking private or final classes or methods
because they are not accessible via inheritance. spock-mockable uses JVM instrumentation to
modify these classes upon class loading and apply looser access restrictions.
In consequence Spock then capable of mocking these classes.
-
Changes methode visibility
privatetoprotected -
Removes
finalfrom classes and methods -
Automatically attaches java agent
-
Redefines classes via Byte Buddy transformation.

Working with Spock Framework 1.3 and 2.0

@Mockable(Person)
class PersonSpec extends Specification {
}io.github.joke mockable@Mockable(packages = "io.github.joke")
class PersonSpec extends Specification {
}More examples can be found in examples.
All @Mockable annotations are scanned during groovy’s compilation phase for classes and registered.
At the start of a test JVM these classes are transformed by the JVM instrumentation
regardless of the actual test class the annotation has been placed on. This might lead to unexpected behaviour.
