At times, I felt Webdriver's drag and drop doesn't make us happy. I found an alternative which helps to perform drag and drop without any hustle. Just follow these 3 steps to make your test case working :)
Step 1: Save this below code in your build location and name it as "drag_and_drop_helper2.js"
(function( $ ) {
var rkeyEvent = /^key/,
rmouseEvent = /^(?:mouse|contextmenu)|click*/,
rdndEvent = /^drag*|drop*/;
$.fn.simulate = function( type, options ) {
return this.each(function() {
new $.simulate( this, type, options );
});
};
$.simulate = function( elem, type, options ) {
var method = $.camelCase( "simulate-" + type );
this.target = elem;
this.options = options;
if ( this[ method ] ) {
this[ method ]();
} else {
this.simulateEvent( elem, type, options );
}
};
$.extend( $.simulate.prototype, {
simulateEvent: function( elem, type, options ) {
var event = this.createEvent( type, options );
this.dispatchEvent( elem, type, event, options );
if(type == "dragstart"){
console.log("dragstart dropTarget: " + options.dropTarget
)
}
if(type == "dragstart" && options.dropTarget){
this._performDND(event, options);
}
var message = "simulated event " + type + " on " + elem.id;
console.log(message);
},
_performDND: function(event, options){
console.log("performing dnd, dropping on " + options.dropTarget.id)
var dropEvent = this.createEvent("drop", {});
dropEvent.dataTransfer = event.dataTransfer;
this.dispatchEvent($(options.dropTarget)[0], "drop", dropEvent, {});
},
createEvent: function( type, options ) {
if ( rkeyEvent.test( type ) ) {
return this.keyEvent( type, options );
}
if(rmouseEvent.test(type)){
return this.mouseEvent( type, options );
}
if(rdndEvent.test(type)){
return this.dndEvent( type, options );
}
},
dndEvent: function(type, options, dataTransfer){
var event = document.createEvent("CustomEvent");
event.initCustomEvent(type, true, true, null);
event.dataTransfer = {
data: {
},
setData: function(type, val){
this.data[type] = val;
},
getData: function(type){
return this.data[type];
}
};
return event;
},
mouseEvent: function( type, options ) {
var event, eventDoc, doc, body;
options = $.extend({
bubbles: true,
cancelable: (type !== "mousemove"),
view: window,

}, options );
if ( document.createEvent ) {
event = document.createEvent( "MouseEvents" );
event.initMouseEvent( type, options.bubbles, options.cancelable,
options.view, options.detail,
options.screenX, options.screenY, options.clientX, options.clientY,
options.ctrlKey, options.altKey, options.shiftKey, options.metaKey,
options.button, options.relatedTarget || document.body.parentNode );
// IE 9+ creates events with pageX and pageY set to 0.
// Trying to modify the properties throws an error,
// so we define getters to return the correct values.
if ( event.pageX === 0 && event.pageY === 0 && Object.defineProperty ) {
eventDoc = event.relatedTarget.ownerDocument || document;
doc = eventDoc.documentElement;
body = eventDoc.body;
Object.defineProperty( event, "pageX", {
get: function() {
return options.clientX +
( doc && doc.scrollLeft || body && body.scrollLeft || 0 ) -

}
});
Object.defineProperty( event, "pageY", {
get: function() {
return options.clientY +
( doc && doc.scrollTop || body && body.scrollTop || 0 ) -
( doc && doc.clientTop || body && body.clientTop || 0 );
}
});
}
} else if ( document.createEventObject ) {
event = document.createEventObject();
$.extend( event, options );
// TODO: what is this mapping for?
event.button = { 0:1, 1:4, 2:2 }[ event.button ] || event.button;
}
return event;
},
keyEvent: function( type, options ) {
var event;
options = $.extend({
bubbles: true,
cancelable: true,
view: window,
ctrlKey: false,
altKey: false,
shiftKey: false,
metaKey: false,
keyCode: 0,
charCode: undefined
}, options );
if ( document.createEvent ) {
try {
event = document.createEvent( "KeyEvents" );
event.initKeyEvent( type, options.bubbles, options.cancelable, options.view,
options.ctrlKey, options.altKey, options.shiftKey, options.metaKey,
options.keyCode, options.charCode );
// TODO: what is this supporting?
} catch( err ) {
event = document.createEvent( "Events" );
event.initEvent( type, options.bubbles, options.cancelable );
$.extend( event, {
view: options.view,

charCode: options.charCode
});
}
} else if ( document.createEventObject ) {
event = document.createEventObject();
$.extend( event, options );
}
// TODO: can we hook into core's logic?
if ( $.browser.msie || $.browser.opera ) {
// TODO: is charCode ever <0 ? Can we just use charCode || keyCode?
event.keyCode = (options.charCode > 0) ? options.charCode : options.keyCode;
event.charCode = undefined;
}
return event;
},
// TODO: does this need type? Can't we just check event.type?
dispatchEvent: function( elem, type, event ) {
if ( elem.dispatchEvent ) {
elem.dispatchEvent( event );
} else if ( elem.fireEvent ) {
elem.fireEvent( "on" + type, event );
}
},
simulateFocus: function() {
var focusinEvent,
triggered = false,
element = $( this.target );
function trigger() {
triggered = true;
}
element.bind( "focus", trigger );
element[ 0 ].focus();
if ( !triggered ) {
focusinEvent = $.Event( "focusin" );
focusinEvent.preventDefault();
element.trigger( focusinEvent );
element.triggerHandler( "focus" );
}
element.unbind( "focus", trigger );
},
simulateBlur: function() {
var focusoutEvent,
triggered = false,
element = $( this.target );
function trigger() {
triggered = true;
}
element.bind( "blur", trigger );
element[ 0 ].blur();
// blur events are async in IE
setTimeout(function() {
// IE won't let the blur occur if the window is inactive
if ( element[ 0 ].ownerDocument.activeElement === element[ 0 ] ) {
element[ 0 ].ownerDocument.body.focus();
}
// Firefox won't trigger events if the window is inactive
// IE doesn't trigger events if we had to manually focus the body
if ( !triggered ) {
focusoutEvent = $.Event( "focusout" );
focusoutEvent.preventDefault();
element.trigger( focusoutEvent );
element.triggerHandler( "blur" );
}
element.unbind( "blur", trigger );
}, 1 );
}
});
/** complex events **/
function findCenter( elem ) {
var offset,
document = $( elem.ownerDocument );
elem = $( elem );
offset = elem.offset();
return {
x: offset.left + elem.outerWidth() / 2 - document.scrollLeft(),
y: offset.top + elem.outerHeight() / 2 - document.scrollTop()
};
}
$.extend( $.simulate.prototype, {
simulateDrag: function() {
var target = this.target,
options = this.options,
center = findCenter( target ),
x = Math.floor( center.x ),
y = Math.floor( center.y ),
dx = options.dx || 0,
dy = options.dy || 0,
target = this.target,
coord = { clientX: x, clientY: y , dropTarget: options.dropTarget || undefined };
console.log("simulateDrag of " + target.id +
" from {" + coord.clientX + ", " + coord.clientY + "} " +
"by {" + dx + ", " + dy + "}" );
this.simulateEvent( target, "dragstart", coord );
coord = { clientX: x + 1, clientY: y + 1 };
this.simulateEvent( document, "mousemove", coord );
coord = { clientX: x + dx, clientY: y + dy };
this.simulateEvent( document, "mousemove", coord );
this.simulateEvent( document, "mousemove", coord );
this.simulateEvent( target, "mouseup", coord );
this.simulateEvent( target, "dragend", coord );
}
});
})( jQuery );
Step 2: Add this method drag_and_drop_js . Change the path you just saved the helper file
private void drag_and_drop_js(WebElement source ,WebElement target){
try {
String js_filepath = System.getProperty("user.dir")+"/src/test/resources/drag_and_drop_helper2.js"; // Change the path here
String java_script="";
String text;
BufferedReader input = new BufferedReader(new FileReader(js_filepath));
StringBuffer buffer = new StringBuffer();
while ((text = input.readLine()) != null)
buffer.append(text + "\n");
java_script = buffer.toString();
input.close();
String load_jquery = "var jqueryUrl = \"http://code.jquery.com/jquery-2.1.1.min.js\";\n"
+ "var scriptElt = document.createElement('script');\n"
+ "scriptElt.type = 'text/javascript';\n"
+ "scriptElt.src = jqueryUrl;\n"
+ "scriptElt.src = jqueryUrl;\n"
+ "document.getElementsByTagName('head')[0].appendChild(scriptElt);";
JavascriptExecutor js = (JavascriptExecutor) driver;
driver.manage().timeouts().setScriptTimeout(10, TimeUnit.SECONDS);
String drag_drop_script = "jQuery(arguments[0]).simulate('drag', { dropTarget: arguments[1] });";
Object o1 = js.executeScript(load_jquery);
Object o2 = js.executeScript(java_script);
Object o3 = js.executeScript(drag_drop_script,source,target);
} catch (Exception e) {
System.out.println("Error :" + e.toString());
}
}
Step 3: Get the source and destination elements, and your are done.
WebElement from = driver.findElement(By.xxxx("xxxx"));
WebElement to = driver.findElement(By.xxxx("xxxx"));
from.click();
drag_and_drop_js(from,to);
Happy Testing!!!
