How to simulate HTML5 Drag and Drop in Selenium Webdriver?

Found working example in python (without using jquery_load_helper.js) - https://gist.github.com/rcorreia/2362544#gistcomment-2708388

As alecxe mentioned: download drag_and_drop_helper.js

# coding = utf-8
from selenium import webdriver
import os
from time import sleep

driver = webdriver.Chrome()
driver.implicitly_wait(10)
driver.get('http://the-internet.herokuapp.com/drag_and_drop')

with open(os.path.abspath('drag_and_drop_helper.js'), 'r') as js_file:
    line = js_file.readline()
    script = ''
    while line:
        script += line 
        line = js_file.readline()

driver.execute_script(script + "$('#column-a').simulateDragDrop({ dropTarget: '#column-b'});")
sleep(2)
driver.quit()

Yes, HTML5 "drag&drop" is not currently supported by Selenium:

• Issue 3604: HTML5 Drag and Drop with Selenium Webdriver

One of the suggested workarounds is to simulate HTML5 drag and drop via JavaScript:

• download drag_and_drop_helper.js
• execute the script via execute_script() calling simulateDragDrop() function on a source element passing the target element as a dropTarget

Sample code:

with open("drag_and_drop_helper.js") as f:
    js = f.read()

driver.execute_script(js + "$('#one').simulateDragDrop({ dropTarget: '#bin'});")

The problem is that it won't work in your case "as is" since it requires jQuery.

Now we need to figure out how to dynamically load jQuery. Thankfully, there is a solution.

Complete working example in Python:

from selenium import webdriver

jquery_url = "http://code.jquery.com/jquery-1.11.2.min.js"

driver = webdriver.Firefox()
driver.get("http://html5demos.com/drag")
driver.set_script_timeout(30)

# load jQuery helper
with open("jquery_load_helper.js") as f:
    load_jquery_js = f.read()

# load drag and drop helper
with open("drag_and_drop_helper.js") as f:
    drag_and_drop_js = f.read()

# load jQuery
driver.execute_async_script(load_jquery_js, jquery_url)

# perform drag&drop
driver.execute_script(drag_and_drop_js + "$('#one').simulateDragDrop({ dropTarget: '#bin'});")

where jquery_load_helper.js contains:

/** dynamically load jQuery */
(function(jqueryUrl, callback) {
    if (typeof jqueryUrl != 'string') {
        jqueryUrl = 'https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js';
    }
    if (typeof jQuery == 'undefined') {
        var script = document.createElement('script');
        var head = document.getElementsByTagName('head')[0];
        var done = false;
        script.onload = script.onreadystatechange = (function() {
            if (!done && (!this.readyState || this.readyState == 'loaded'
                    || this.readyState == 'complete')) {
                done = true;
                script.onload = script.onreadystatechange = null;
                head.removeChild(script);
                callback();
            }
        });
        script.src = jqueryUrl;
        head.appendChild(script);
    }
    else {
        callback();
    }
})(arguments[0], arguments[arguments.length - 1]);
