Spock structure: how can I automatically declare the state of an object to reset after BOM completes

I have a Spring service A

that uses a service internally B

.

I want to:

• Mock service B
  
  
• Install the sent version to the service A
  
  
• Testing A
  
  behavior
• Install a previous version of the service B
  
  for maintenance A
  
  (reset state)

The problem is with the last step - I can remember B

in setup

and set it in stages cleanup

. But can I set it up automatically (something similar to @ConfineMetaClassChanges

)
