Why does the yaf framework access route always access the INDEX method under the INDEX controller under INDEX

1. Recently learn yaf to see the manual said default routing, after a series of installation, enter the URL to show Hello World! I am Stranger this is normal!

2. But I create a new public function testAction method in the Index.php file under controlers . Routing access http://sitename/Index/Index/test, always accesses the contents of the indexAction method!

3. Ask for God"s guidance! (also: if I want to classify the controller, for example, the directory is controllers/son/son.php , the controller in this file inherits the controllers/father.php directory format, how should I set the route?)

4. The table of contents and various configurations are attached below!

< hr > < H2 > Nginx configuration < / H2 >

        location / {
                try_files $uri $uri/ /index.php;

                if (!-e $request_filename) {
                        rewrite ^(.*)$ /index.php?s=$1 last;
                        break;
               }
               -sharp 
            -sharp    if (!-e $request_filename) {
            -sharp        rewrite ^/(.*) /index.php/$1 last;
            -sharp    }
        }

/**

    public function indexAction($name = "Stranger") {
        //1. fetch query
        $get = $this->getRequest()->getQuery("get", "default value");

        //2. fetch model
        $model = new SampleModel();

        //3. assign
        $this->getView()->assign("content", $model->selectSample());
        $this->getView()->assign("name", $name);

        //4. render by Yaf, FALSE, YafRender
        return TRUE;
    }

    public function testAction()
