Để tạo DragEvent, dùng protractor API. Tài liệu chính thức nói:
The browser.get method loads a page. Protractor expects Angular to be present on a page, so it will throw an error if the page it is attempting to load does not contain the Angular library. (If you need to interact with a non-Angular page, you may access the wrapped web driver instance directly with browser.driver).
Cũng dùng pattern:
browser .actions() .dragAndDrop(myEle, {x:100,y:100}) .perform();
