如何使用 ArchUnit 检查是否在正确的类中调用了构造函数？

Question

有什么办法可以用 ArchUnit 来执行这样的规则：

@ArchTest
    static final ArchRule events_must_be_created_by_aggregates =
            noConstructors().that().areDeclaredInClassesThat().areAssignableTo(Event.class).should().beCalledInClassesThat().areNotAssignableFrom(Aggregate.class)
                    .because("the aggregate should manage its own lifecycle and events");

这里的问题是 beCalledInClassesThat 不存在，我找不到任何可以让我实现这样的测试的东西。

每当您错过预定义的 fluent API 中的某些内容时，请尝试定义自定义谓词/条件。 就你而言：这对你有用吗？

@ArchTest
static final ArchRule events_must_be_created_by_aggregates = constructors()
    .that().areDeclaredInClassesThat().areAssignableTo(Event.class)
    .should(new ArchCondition<JavaConstructor>("be called from aggregates") {
        @Override
        public void check(JavaConstructor constructor, ConditionEvents events) {
            for (JavaConstructorCall call : constructor.getCallsOfSelf()) {
                if (!call.getOriginOwner().isAssignableTo(Aggregate.class)) {
                    events.add(SimpleConditionEvent.violated(call, call.getDescription()));
                }
            }
        }
    });
