如何使用junit

Question

班级

@Info(name = "ABC", version = "1.1.1")
public class Test implements TestPlugin{
}

@Info是@interface注释

我想编写junit测试用例来验证它的@info名称和版本，我已经通过了。

您可以使用反射：

Annotation annotation = Test.class.getAnnotation(Info.class);

        if(annotation instanceof Info){
            Info info = (Info) annotation;

            assertEquals("ABC", info.name());
            assertEquals("1.1.1", info.version());
        } else {
            fail("Did not find annotation");
        }
