### Question:
CheckAllGroupPositionValidator implements ConstraintValidator<CheckAllGroupPosition, List<ClientQueryGroup>>,
        ValidationErrorDescriptorBuilder { @Override public void initialize(CheckAllGroupPosition constraintAnnotation) {}  @Override void initialize(CheckAllGroupPosition constraintAnnotation); @Override boolean isValid(List<ClientQueryGroup> groups, ConstraintValidatorContext context); @Override ErrorDescriptor build(ConstraintViolation violation);  }### Answer:
@Test public void initialize() { CheckAllGroupPosition mock = mock(CheckAllGroupPosition.class); objectUnderTests.initialize(mock); verifyZeroInteractions(mock); }
