I have a class that looks like this:

public class A {

   private B b1 = new B();

   private C c = new C();

   private B b2;

}

I want to write an ArchUnit test that finds all the fields in class A that are of type B and that are initialized. So in this case, just field ‘b1’.

I wrote a test like this, but can’t finish it. Is this even possible?

 @ArchTest
  void dontInitialize(JavaClasses classesToTest) {
    noFields().that().haveRawType(DescribedPredicate.describe("that is a B object", type -> {
      return type.isAssignableTo(B.class);
    })).should(new ArchCondition<JavaField>("") {
      @Override
      public void check(JavaField javaField, ConditionEvents conditionEvents) {
        // ???
      }
    });
  }
