Dragg and Drop on Winapp driver and Appium

Scenario

The basic scenario here is having a windows desktop application with the drag and drop capability.
Testing this application, you are using Appium over Winappdriver.
The test I am attending to perform is a simple drag and drop.

The above setting and scenario, isn't rare! actually it is a common case in desktop apps, that it is why it is so troubling to find that drag and drop is an issue.

Searching the web, I found many ways of accomplishing the D&D, which basically I can split to two groups, the first one is using the driver.Mouse actions, where I will use a mouseDown, mouseMove and MouseUp, the second method will use the Actions object and will consist of actions.dragAndDrop() (Yes, there is such a function), or will do it the long way of Actions.ClickAndHold().MoveTo().Release().

But it seems that in some cases, both approaches just don't work.
Let me be clear, this is a HUGE bug!
There is a workaround, but it is a huge bug (especially when having a non working actions.dragAndDrop()).

Outline

I will write here 7 options to write drag and drop, which will be split to the above 2 methods, then i will give a link to the problem as it is outlined by a frustrated stackoverflow user, and will finish with the working workaround.

First way - Using the session.Mouse

        public void dragAndDropMouse1(WindowsElement source, WindowsElement destination) {
            session.Mouse.MouseMove(source.Coordinates);
            session.Mouse.MouseDown(null);
            session.Mouse.MouseMove(destination.Coordinates);
            session.Mouse.MouseUp(null);
        }

        public void dragAndDropMouse2(WindowsElement source, WindowsElement destination) {
            session.Mouse.MouseDown(source.Coordinates);
            session.Mouse.MouseUp(destination.Coordinates);
        }

        public void dragAndDropMouse3(WindowsElement source, WindowsElement destination) {
            session.Mouse.MouseMove(source.Coordinates, 2, 2);
            session.Mouse.MouseDown(null);
            session.Mouse.MouseMove(destination.Coordinates, 2, 2);
            session.Mouse.MouseUp(null);
        }

Second way - Using the Actions

        public void dragAndDropAction1(WindowsElement source, WindowsElement destination) {
            actions.DragAndDrop(source, destination).Build().Perform();
        }

        public void dragAndDropAction2(WindowsElement source, WindowsElement destination) {
            new Actions(session).DragAndDrop(source, destination).Build().Perform();
        }

        public void dragAndDropAction3(WindowsElement source, WindowsElement destination) {
            new Actions(session).ClickAndHold(source).MoveToElement(destination).Release().Perform();
        }

        public void dragAndDropAction4(WindowsElement source, WindowsElement destination) {
            actions.MoveToElement(source).Perform();
            actions.ClickAndHold().Perform();
            actions.MoveToElement(destination).Perform();
            actions.Release().Perform();
        }

The actual problem can be found here in this stackoverflow thread

The Solution

    public void dragAndDropWorkaround(WindowsElement source, WindowsElement destination) {
            new Actions(session)
                .ClickAndHold(source)
                .MoveByOffset(1, 1)
                .MoveToElement(destination)
                .Release().Perform();
     }

The solution uses a slight move of the mouse cursor before completing the drop, this is a huge bug in Appium's code somewhere, and for now this workaround works

Profiling Java @ 2019

A good profiler can really help you in your work while coding Java (I assume while coding any coding language but I am referring to Java here) It can find memory leaks (Which object and how many of it takes the most of your limited memory?), CPU bottlenecks and other surprising data like the time consumed by each network call / DB query etc. Thus it is not so surprising to find many different java profilers around. I will try to map here the Java profiling tools lying around My short list of requirements will include the following: Profiler Requirements Constantly updated profiler (how a profiler built to profile Java6 will behave with Java11?) Clear GUI - As I will want to dive into the profiling data - it will be much simpler using UI Free (With a big advantage to the open sourced ones) (Optional) Remote profiling List of Profilers Dead Profilers (At least 5 years without an update) JIP - Java Interactive Profiler  - Last update 2010 Profiler4J - Last U...

Ant Explorer graphical Ant build tool

Every serious java developer needs to create or edit some ant building script. Eclipse offers nice ant handling features which make the task much easier, eclipse's plugin (which is embeded into eclipse since version 3.1 or so) understands the ant scripting language thus enables not only syntax coloring but also nice mouse hovering which reveals values of properties, variable names which enables finding the source of each variable and also some nice debugging features. But, there is one field in which eclipse's ant handling lacks perfection, its in viewing the whole build file in one gaze graphically feature, that feature isn't supported by eclipse. Luckily enough, it is supported by YWorks, which created a nice and free util which loads an ant script file and shows it in a beautiful and so very useful way. I think that this util (which was released as a standalone as well as an eclipse and idea) is a must for any serious java developer. Unluckily, YWorks have remo...

Start Working with AutoIT

I have decided I needed a quick GUI creator which can create a small exe file displaying the GUI, with no system dependencies like a .NET framework or Java runtime. What options do I have for a Quick GUI Creator? Maybe there are many options I am not aware of, but after extensive searching I found these two: Auto Hot keys AutoIT (Saw some recommendations to try Delphi or Pascal for this task but I passed) Both tools began from the same code source, autohotkeys branched off and continued to be open source while AutoIT is more commercial. I have compared the two (well, not actually compared, just google'd out other's comparisons) and found out that the AutoHotKeys is slightly better and is more open sourced (which makes it the better solution) but lacks in one field which is crucial for me - the script syntax is awful!  That tipped the balance (as a programmer i couldn't stand AHK's syntax) so I chose AutoIT. How to get Started with AutoI...
