我已经加载了一个包含地图的页面,如下所示：
http://tombatossals.github.io/angular-leaflet-directive/examples/center-example.html

并且这个量角器测试不会平移地图,对所选图像的dragAndDrop操作似乎不起作用.

describe('Panning map',function() {    
    var ptor,driver;
    beforeEach(function() {        
        ptor = protractor.getInstance();
        browser.get('center-example.html');
        driver = ptor.driver;
    },30000);

    it('should update the center value if the map is dragged',function() {
        var el = element(by.xpath('.//img[contains(@class,"leaflet-tile-loaded")][1]'));
        browser.actions().dragAndDrop(el.find(),{ x: 40,y: 40 }).perform();
        ptor.sleep(2000);
        expect(element(by.model("london.lat")).getAttribute("value")).toBe('51.505');
        expect(element(by.model("london.lng")).getAttribute("value")).toBe('-1.09');
    });
});

这可能是dragAndDrop操作不适用于这样的例子的原因？
