模拟静态方法用参数抛出错误

Question

我有自定义的Log4j2 appender：

    @Plugin(
            name = "MyAppender",
            category = "Core",
            elementType = Appender.ELEMENT_TYPE)
    public class MyAppender extends AbstractAppender {
    
        private static final Logger LOGGER = LoggerFactory.getLogger(MyAppender.class);
        private final Lock lock = new ReentrantLock();
    
    
        private MyAppender(final String name, final Layout<? extends Serializable> layout ) {
            super(name, null, layout, false, Property.EMPTY_ARRAY);
        }
    
    
        @Override
        public void append(LogEvent event) {
           ....
        }
    
        @PluginFactory
        public static MyAppender createAppender(
                @PluginAttribute("name") String name,
                @PluginElement("Layout") Layout<? extends Serializable> layout){
            if (layout == null) {
                layout = PatternLayout.createDefaultLayout();
            }
            return new MyAppender(name, layout);
        }
}

我想模拟createappendermethod:

 try (MockedStatic<MyAppender> mocked = mockStatic(MyAppender.class)) {
            MyAppender appender = Mockito.mock(MyAppender.class);
            mocked.when(() -> MyAppender.createAppender("myAppender", Mockito.any(Layout.class))).thenReturn(appender);
              ....
        }

根据我的理解，模仿静态方法是不好的，因为它挑战设计级别的决策。如果我错了，请有人来指导我。
