Hot to reset a method mock in Spock?-CodePudding

I had a mocked bean in a configuration:

@Profile('test')
@Configuration
class TestSecurityConfig {
  private final mockFactory = new DetachedMockFactory()
  @Primary @Bean
  AuthUserDetailsProvider authUserDetailsProvider() {
      mockFactory.Stub(AuthUserDetailsProvider)
  }
}

By default, I mock a method call is setup() method for all tests.

def setup() {
    authProvider.authenticationPrincipal >> random(authUserDetails)
}

By in a specific test, I need to override the method mock

def 'exercise missed user processing'() {
    given: 'no user data'
    authProvider.authenticationPrincipal >> emptyUser
    ...
}

But it doesn't work. How can I override a method mocking in Spock? Is there any way to reset mock interceptions manually?

Whatever you put in setup will be executed before each test. If you don't want that, then the code probably shouldn't be in setup.

If by "override" you mean undo what was done in setup and then do something else, I am not aware of a way to do that.

Not that I am aware of. It is unusual to tell the mock that you want a certain behavior and later tell the mock that you have changed your mind.

CodePudding user response：

Interactions defined in then blocks will have precedence over those defined in given/setup, for the preceding when block. Normally, you pare them with assertions, i.e., 1 * ... but it works for plain stubbing too.

import spock.lang.*

class ASpec extends Specification {
  List myList = Mock()
    
  def setup() {
    myList.get(0) >> 1
  }
    
  def "default behavior"() {
    expect: 
    myList.get(0) == 1
  }
    
  def "override behavior"() {
    when:
    def result = myList.get(0)

    then:
    myList.get(0) >> 42
    result == 42
  }
}

So in your case:

def 'exercise missed user processing'() {
    when:
    ...

    then:
    1 * authProvider.authenticationPrincipal >> emptyUser
    ...
}
