如何使用 ArchUnit 檢查是否在正確的類中調用了構造函數？

Question

有沒有辦法用 ArchUnit 強制執行這樣的規則：

@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");

這里的問題是beCalledInClassesThat不存在，我找不到任何可以讓我實現這樣一個測試的東西。

每當您錯過預定義的 fluent API 中的某些內容時，請嘗試定義自定義謂詞/條件。 在您的情況下：這對您有用嗎？

@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()));
                }
            }
        }
    });
