I was just curious about how does Uipath process render GUI to interact with various application in unattended mode without screen. I am trying to build my own RPA system for few specific use cases but I am stuck at running those process in unattended. Because to interact with application(click etc) it requires GUI to render.
Thanks
According to this article (and a little bit simplified) they either use the console session (which is a well-known solution / workaround) or they create RDP Sessions programmatically using the FreeRDP framework. (I have tried my luck with FreeRDP but most of it's features are disabled in corporate environments)
If you really want to dig in the whole thing, Microsoft provides a framework for implementing own Remoting Solutions. Theoretically you could implement your own protocol with lower security boundaries and by not destroying the GUI if the remote session is not active (disconnected but not closed)
It's based on the coordinates of the controls and the text they contain. It recognizes graphical objects by their platform-specific attributes. In very particular scenarios, where object recognition is not available such as with RDP, it uses image and OCR text-based automation.

What is the best way to control a program's user interface (clicking, entering text, drop down selection, etc) when the program has no available API?
I've heard of AutoHotKey and FlaUI and watched a few videos but haven't seen a great example yet. Before I go too far, is this the best direction/method?
Thanks!
FlaUI is a fully fledged UI Testing library that allows you to automate all aspects of a Windows application. As author of it, I of course recommend it. If you do have a bit of programming know how, it should be fairly easy to use. In case you just want some scripts to run locally, you don't even need Visual Studio or Visual Studio code, you can just use RoslynPad for example and directly create and run your code there.
I use this all the time for small automations, heck even sometimes to input very long passwords in a remote machine where I cannot use copy/paste.
I am working on implementing accessibility (for visually impaired individuals) for one of our web application. It need to be ARIA compliant. Right now we are testing our changes with screen reader manually.
For example we have Tree control in our application. I open NVDA screen reader and then navigate through my Tree Nodes. NVDA screen reader speaks out
Node XYZ expanded, (When I expand XYZ node with right arrow key)
Node XYZ collapsed, (When I collapse XYZ node with left arrow key)
Along with the voice it also write down this text.
But all this is manual. Now we want to setup automated test cases for the same so that any regression bugs can be caught by are test cases. Do there exist any such tool which we can use to automate our test cases. Any direction will be helpful.
PS: Just for a sake of comparison. We have nunit to write test cases for c# application. After writing test cases we integrate them into our build process. Any breaking change is caught when we run the build. I am looking for something similar to test out our aria compliance and screen reader's behavior with our web application.
I don't know of any existing tools for testing screen readers, however, there are accessibility APIs that test websites and web applications.
axe-core from Deque Systems is widely used and well-supported.
I wrote a python package to run automated web accessibility tests that uses axe-core and selenium.
While it isn't quite what you are looking for, it does cover about 60% of accessibility guidelines, including aria roles and attributes. It should help with determining screen reader usability.
You could integrate axe into C#, similar to my python package and the Java package, also created by Deque.
I hope this helps!
It sounds like you're already performing some pretty good manual accessibility testing against your web application, which no automated testing tool is going to be able to replicate completely. That said, if you're looking to take care of any low-hanging fruit with an automated solution, like Kimberly suggested, there are several automated accessibility testing tools out there that you can relatively easily integrate into your existing web application's testing framework that might help you.
One such tool is Continuum, which doesn't have a C#-based library offering at the moment, but could be used in a separate testing framework to be run against your web application after it has already been built. This may be preferable depending on your use case, as code linters for accessibility aren't perfect and are highly language-dependent, whereas testing the HTML of your web application more closely matches the screen reader use case you say you're trying to test for. You could even integrate Continuum into your existing CI/CD process to make sure your application is tested during development as opposed to afterwards, to reduce your manual accessibility testing load.
Continuum has a few sample projects to get you started, depending on your technologies of choice. Free versions are available at webaccessibility.com if you're interested. Most of them are Java- or JavaScript-based at the moment.
Appreciate this is quite an old question, but having explored this area a lot recently thought was worth updating with the state as of 2023 as there is now some progress in this space.
Current tooling available at time of writing (that I’m aware of, may not be exhaustive):
guidepup - NodeJS automation for VoiceOver and NVDA supporting all keyboard commands and getters for spoken phrases (disclaimer: I’m the author).
auto-vo - CLI for navigating sequentially through a page with VoiceOver and reporting the spoken phrases, also exports a separate Node module for some interactions with VoiceOver.
screen-reader-reader - NodeJS automation for VoiceOver and NVDA for starting, stopping, and getting spoken phrases.
web-test-runner-voiceover - NodeJS plugins for #web/test-runner to automate VoiceOver testing.
nvda-testing-driver - .NET automation for NVDA supporting all keyboard commands and getters for spoken phrases.
assistive-webdriver - NodeJS implementation of a Webdriver server that allows remote testing of screen readers (e.g. NVDA, JAWS) running in a VM.
As stated in other answers, there are also a number of static analysis tools such as axe, as well numerous browser extensions offering similar static analysis, and companies such as Assistiv Labs offering remote environment services to interact with screen readers manually (similar to SauceLabs/BrowserStack/etc. but for screen readers, magnification etc. - no affiliation and haven’t used services so can’t vouch, simply an observation).
Worth calling out that none of these cover the full range of a11y requirements - there is more to a11y than just screen readers. A combined/layer approach including automation, manual testing, and user testing likely preferred.
Is there a possibility to do a automation testing of application developed using WxWidgets on windows platform? If so how do I do that?
wxWidgets uses native widgets so any automated testing solution for Win32 programs would work with wxWidgets applications. However IME the typical "point-and-click" tests are not that great in practice and it's better to write the tests for the GUI code in the same way as you do it for the rest of the program.
There are two problems that need to be solved when doing it though: first, how to trigger various actions in the GUI. This is addressed by wxUIActionSimulator. It is not perfect, but if your application has a reasonable keyboard interface (as it should), it should be enough.
The second problem is related to the control flow in the GUI applications: if some action results in opening of a modal dialog, the test can't continue until the dialog is closed by user, which is inappropriate for unattended tests. wxWidgets provides (still somewhat experimental and not documented yet) wxTEST_DIALOG macro for dealing with this, its use is explained in this comment.
Combination of these two approaches allows to write tests for the real-life GUI applications and, moreover, the tests are portable and not limited to Windows platform.
Just new on software testing...
Regarding testing, I think GUI applications are pretty difficult to automate. Some testing involves with interacting particular GUI objects in particular sequence (e.g., clicking buttons). The interface often changes from one window to another. And the timing and sync sometimes also pose an issue (e.g., recording mouse clicks and replaying may screw up).
Is there any solution for testing such applications with less human labour? Thank you for sharing your experience.
Yes, GUI apps are indeed tough to automate. Regardless of the app's technology (Swing, web, WPF, iOS), you first have to focus on automating high-value tests. Moreover, test automation shouldn't be at just the GUI level, it should be a mix across unit, integration, and functional (GUI) tests too.
Are you working on a web app? If so, have a look at great open source tools like Watir or WebDriver. (I'll also pitch Telerik's Test Studio to you; however, for full disclosure I'm their evangelist for that tool.)
Desktop applications (or mobile) bring a lot of challenges to automation, and it's totally dependent on what platform you're working with. Test Studio supports WPF, but you can also look to other commercial and a few free tools. I don't know of any tools for Swing apps, but that lack of knowledge is due to me having been out of that domain for many years. (And maybe I'm so out of it that Swing's not even the normal Java GUI toolset...)
iOS and Android are tough ones to find reliable automation tools for. I know the Frank framework/API will work on iOS (Test Studio has a free recorder in the App Store), but I don't know of any other tools that reliably support the extraordinary matrix of Droid hardware and OS versions.
Regardless of your platform and toolset, you need to learn the basic approaches for dealing with GUI testing: focus on high value tests, learn to avoid duplication through approaches like Page Object Pattern, learn how to deal with synchronization/timing issues in your specific application.
It's a long haul, but if you work carefully it's totally worth it.
(And fun, too, IMO.)
What tools are useful for automating clicking through a windows form application? Is this even useful? I see the testers at my company doing this a great deal and it seems like a waste of time.
Check out https://github.com/TestStack/White and http://nunitforms.sourceforge.net/. We've used the White project with success.
Though they're mostly targeted at automating administration tasks or shortcuts for users, Autohotkey and AutoIT let you automate nearly anything you want as far as mouse/keyboard interaction.
Some of the mouse stuff can get tricky when the only way to really tell it what you want to click is an X,Y coordinate, but for automating entirely arbitrary tasks on a Windows machine, it does the trick.
Like I said, they're not necessarily intended for testing purposes, so they're not instrumented for unit test conventions. However, I use them all of the time to automate stuff that isn't testing related.
You can do it programmatically via the Microsoft UI Automation API. There's an MSDN Magazine article about it.
Integrates well with unit test frameworks. A better option than the coordinate-based script runners because you don't have to rewrite scripts when layouts change.
There's a couple out there. They all hook into the windows API to log item clicks, and then reproduce them to test.
We're now mostly web based (using WatiN), but we used to use Mercury Quicktest.
Don't use Quicktest, it's awful for a tremendously long list of reasons.
This is what i was looking for.
