ArchUnit 确保注释存在

Question

给定 ArchUnit 库版本 0.12:

是否可以测试场景 "methods annotated with A should also be annotated with B or be declared in a type annotated with B"？

示例：

A.java

@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
public @interface A {
}

B.java

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
public @interface B {
}

TestCases.java

public class TestCases {

    static class ShouldFail {

        @A
        public void m() {
        }
    }

    static class ShouldPass {

        @A
        @B
        public void m() {
        }
    }

    @B
    static class ShouldPassToo {

        @A
        public void m() {
        }
    }
}

我尝试了什么？

我认为 ArchConditions.beDeclaredInClassesThat 可以完成这项工作，所以我准备了以下规则：

MethodsShouldConjunction rule = methods()
    .that()
    .areAnnotatedWith(A.class)
    .should()
    .beAnnotatedWith(B.class)
    .orShould(beDeclaredInClassesThat(areAnnotatedWith(B.class))); //<-- doesn't compile

...但显然我误解了上述方法的目的。该实用程序的 Javadoc 根本没有帮助。我可以用满足断言 "methods declared in a type annotated with B"?

的任何有效内容替换最后一行吗

Answer 1

原来我不必要地尝试将参数传递给 orShould 方法。为了实现我的目标，应该使用无参数方法扩展规则：

methods()
    .that()
    .areAnnotatedWith(A.class)
    .should()
    .beAnnotatedWith(B.class)
    .orShould()
    .beDeclaredInClassesThat()
    .areAnnotatedWith(B.class);
