WinAppDriver (short for Windows Application Driver) is a free test automation tool for Windows desktop apps developed by Microsoft. It can run as a standalone as well as a plugin for Appium. Thus, if you are already running Appium’s server, then a request for Win10 app automation will launch WinAppDriver.exe.
Pros:
Cons:
Bottom Line: A fast-growing tool that will that will provide you with better support for using Appium to test Windows apps.
AutoIT is a standalone (doesn’t require any configuration) and small footprint tool, that simulates mouse and keyboard clicks . It activates the binary files of the tested app using a Reflection.
The AutoIT comes with dedicated IDE, and is compatible with recordings and coding in its own scripting language (very similar to BASIC syntax).
Pros:
Cons:
Based on a unique coding language (that requires learning).
Bottom line: No wonder AutoIT is one of the most popular tools in its field.
Winium is a new open source framework, that’s based on Selenium and consists of 3 parts:
Pros:
In case you are already using Selenium WebDriver and familiar with its API, using Winium is straightforward.
Cons:
As a result of it’s being a new project, few struggles come in the way. Its API still isn’t complete and not on the same maturity level as other tools in this category.
Bottom line: In case you are considering Winium, my advice is to wait until it’s more baked.
White is a library for automation of desktop apps. It started as a small open source project and then became a part of TestStack which consists of a variety of open source code projects for automated and manual testing.
White supports a variety of automation technologies: Silverlight, WPF, WinForms, Win32 and SWT in Java. It’s possible to write White tests in any language supported by .NET.
Pros:
Cons:
Requires installation of UI Automation Verify library.
Bottom Line: One strength among many is the impressive API that is highly extensive and simple to use.
Although the project started for Linux, nowadays it supports MAC (PyATOM version) and also Windows OS (Cobra version). The LDTP comes along with an Editor of its own and among other activities it also supports recordings.
Pros:
Its library is very rich and is compatible with a wide range of environments/ languages compared to other tools in this list. LDTP allows performance monitoring (Memory and CPU) while executing tests on an application.
Cons:
There isn’t enough documentation, many pages are broken, which makes learning API much more difficult.
Bottom line: An amazingly capable tool, but has disadvantages that lower its rank because it is immensely hard to learn.
What makes Sikuli exceptional is the object recognition by images , while other tools in the list recognize the objects by objects properties. Clearly, there are advantages and disadvantages for both methods. The image recognition is performed by an background engine that is capable of comparing a pixel to a pixel at BitMap level.
When working with Sikuli, initially we’ll form a Repository of pictures (screenshots from the application) which will become the inspiration (Expected Result) for determining points and rectification which will be activated while running the program (Actual Result).
The tool comes with an IDE of its own, which includes a unique scripting language and an API to which it’s possible to connect in Java and C#. Additionally, Sikuli offers visualization and functional tests.
Pros:
Since the technique of comparing pictures doesn’t rely on object properties, Sikuli can interpret everything we’ll create – while executing one test, it is possible to check a DB table, a Windows window, also a mobile application and a response from the server without dedication any efforts or special configurations.
Cons:
Constant maintenance of the existing pictures stock for each product change.
Bottom line: The recommendation is to implement this tool in specific occasions only.
The PyWinAuto is a Python library that provides a collection of functions that make operations on Windows (controls and windows dialogs). The library presents a wide set of operations, is clear and user friendly.
Pros:
Cons:
Those who don’t already use Python, will need to open a new Python project.
Bottom line: A library with a variety of capabilities which is highly recommended especially for Python experienced professionals.
These tools are distinctively different than the rest, in the way that they aren’t directly destined as test automation tools for desktop applications, but act as classes to simulate activities of the keyboard and mouse. Whereas, the Robot Class could be used with Java and Win.form is for .Net.
Pros: Solely a class
Cons: Solely a class
Bottom line: We’ll use the class for uncomplicated scenarios only ( for instance, choosing an image from the File System), no QA is needed.
There is a simple case for why end-to-end UI testing is impossible without automated image comparison. Absence of a screenshot comparison tool puts your product at risk of shipping with visual bugs which rarely go unnoticed by users. No sane QA engineer is willing to accept that risk.
So do you automate image comparison when testing UIs? And if yes, what automation tool do you use? Is it a simple module for WebDriver (or other code-based solution) or a dedicated visual CSS regression testing tool?
Let’s look at the popular tools and platforms that QAs leverage to compare screenshots when testing web UIs.
In this post, we’ll find out if the functionality of these image comparison tools meets the real-life requirements of UI testing.
Resemble.js is as an image comparison module that PhantomCSS uses to compare screenshots taken by CasperJS. Aside from this, Resemble.js can function as part of any image analysis setup. In fact, it serves as a core of other screenshot comparison tools on this list. The module offers basic image comparison functionality and a clean syntax:
There’s one issue with Resemble, though. The tool uses a somewhat simplistic pixel matching algorithm that allows for tolerance of the number of different pixels. This is not practical for comparing screenshots of web pages where content will often shift by just a few pixels resulting in image comparison fails.
[UPDATE]: the developers of this image comparison tool have ceased maintaining it due to the introduction of the headless Chrome.
PhantomCSS is a screenshot comparison module that works in tandem with Resemble.js and offers a visual/CSS regression testing library for PhantomJS and SlimerJS. Both PhantomCSS and Resemble.js are brainchildren of Huddle, and both of them have a solid developer support and top-notch documentation
The drawback of PhantomCSS is it’s overhead-to-value ratio. Since the tool is not for a real browser that people use, your test results may differ from what the users actually see. On the other hand, the overhead of setting it up is comparable to that of a real browser. Due to this, there is little incentive to choose PhantomCSS for modern commercial projects.
[UPDATE]: WebdriverCSS is no longer maintained.
While PhantomCSS mainly targets headless browsers, there are quite a few solutions for automation screenshot comparison in real browsers. WebdriverCSS is one of these solutions. This image comparison tool is based on WebdriverIO, which makes for a lot of neat functionality. The tool allows you to write scripts in JavaScript, and it’s compatible with major TDD and BDD frameworks.
One more reason to like WebdriverCSS is the WebdriverCSS Adminpanel — a clean, nothing-extra-style dashboard with a slider for manual image comparison. Sure, setting up the admin panel adds overhead, but the overall experience of using the dashboard feels rewarding.
Puppeteer is a rather popular Node library that drives Chrome (and Chromium) in both headless and full mode. One of the features available out of the box in Puppeteer is screenshot-taking with page.screenshot().
Launched in April 2018, puppeteer-screenshot-tester is a tiny, MIT-licensed npm package that extends this screenshot-taking functionality. This image comparison tool uses node-resemble-js under the hood. It allows for automatic comparison of full-page screenshots, adding decent screenshot comparison functionality to Puppeteer.
Wraith is a Ruby-based tool for automated screenshot comparison. It uses ImageMagic for diffing, and works on Windows, Mac, and Linux. This tool is authored by the development team of BBC News, and it enables screenshot comparison in two distinct modes:
Wraith is another solution that targets headless browsers. With that said, it works for Chrome (Selenium WebDriver with Chromedriver).
This image comparison tool is no longer maintained.
One cool thing about Huxley is that it adds record-playback on top of image comparison. The tool uses simple pixel matching and diffing, and it supports CI. Huxley will automatically notify you if there’s been a visual regression, and it will warn you in case you forgot to run your tests.
Another cool thing about this tool is that it was initially a project of Facebook and Instagram. As for the not-so-cool thing, Facebook dropped the support of this tool, even though Huxley’s code base is still available on GitHub for use or further development.
The development team at Yahoo positions Blink-diff as a lightweight screenshot comparison tool. The solution enables testers to automate image comparison via the command line or by adding a BlinkDiff object to the project code.
Some of the notable features include cropping and block-out (i.e. ignoring particular UI regions). Besides, the tool breaks down image comparison automation into three distinct comparison modes:
This tools is MIT-licensed and available on NPM.
Pix-diff is a Protractor plugin that uses the image comparison module forked from Yahoo’s Blink-diff. It offers the same three modes of comparison (pixel-by-pixel, perceptual, and context), and it allows you to compare both whole images and separate image areas.
BackstopJS is a config-driven CSS testing tool that includes image comparison as one of its core features. The tool enables QAs to test responsive layouts across multiple pre-specified viewport sizes, and it offers a wide array of reporting functionality. Backstop works with CasperJS, and it seems like a neat tool for web developers who don’t mind spending some extra time writing tests.
A lightweight plugin for Protractor, this tool enables testers to save and compare UI areas and full-scale screenshots on desktop and mobile. Protractor-image-comparison uses ResembleJS under the hood, has the concept of baselines, and it targets both mobile websites and hybrid apps on mobile.
.ignoreLess()
, .ignoreNothing()
)A neat option for the fans of Python, Needle offers image comparison functionality for Selenium. Aside from merely comparing visuals, Needle provides testers with tools for analysis of calculated CSS values.
According to this tool’s developer Christoph Burgmer, CSS Critic is a “tiny framework that allows you to unit-test your CSS”. The tool does this by comparing the screenshot of the UI to a reference image. It doesn’t offer much aside from simplistic image comparison, though.
Besides the barebones functionality, there’s definitely a lot of room for improvement in the browser support department. As of today, CSS Critic is compatible with Firefox only.
Gemini’s major claim to fame is the fact that it’s from Yandex, the company that has authored the BEM methodology of CSS development.
As far as more practical aspects go, Gemini creates an impression of a solid screenshot comparison tool. It works with Selenium and it supports every major browser (including IE8+).
Just like the more advanced image comparison tools on this list, Gemini is capable of testing separate areas of the web page. Besides, the tool is able to ignore inessential differences (like rendering artifacts) which minimizes false positives. Gemini also features a dashboard module that simplifies UI testing (even though this dashboard looks rather simplistic).
One great thing about Shoov is the slider-based dashboard that seems like a useful thing for manual examination of screenshot differences. When it comes to the automation testing, simple image comparison remains the tool’s core functionality.
Let’s take another quick look at the screenshot and image comparison tools we’ve mentioned so far. Below, you can find a comparison matrix that sums up the basic features and benefits that these tools offer. We’ll exclude Resemble.JS from comparison because it’s essentially an image comparison module used by other tools (like PhantomCSS).
Tools / Features | GUI / VIsual Dashboard | Browser type | Distinguishing features |
---|---|---|---|
Resemble.js | No | Real and headless | Low-level image comparison module used in other tools |
PhantomCSS | No | Headless | Still is a solid option for SlimerJS. |
WebdriverCSS | Yes | Real | Default option for WebDriver.io |
Puppeteer-screenshot-tester | No | Real and headless | Lightweight library that adds image diffing to Puppeteer |
Wraith | No | Headless* | Comparison across domains and product versions |
Huxley | No | Real and headless | Webdriver-based record-playback with a built-in image comparison tool |
Blink-Diff | No | Real and headless | Three comparison modes: pixel-perfect, perceptual, context |
Pix-diff | No | Real and headless | Blink-Diff-based screenshot comparison tool for Protractor |
BackstopJS | No | Headless | Smart timeouts for Progressive apps, SPAs and AJAX content |
Protractor-image-comparison | No | Real and headless | Good Appium support |
Needle | No | Real and headless | Python-based tools for image comparison (can use the PIL engine, ImageMagick, or PerceptualDiff) |
CSS-critic | No | Real and headless | Image comparison-based “unit testing for CSS” |
Gemini | Yes | Real and headless | Good cross-browser functionality, lots of plugins |
Shoov | Yes | Real and headless | Drupal-friendly |
*Technically speaking, you can add real browser support to Wraith, but you’ll have to use an outdated module.
As I’ve mentioned earlier, screenshot comparison is vital for effective UI testing — but does this mean that screenshot comparison is enough? To give an informed answer to this question, let’s once again look at the typical changes that web pages undergo throughout their life cycle:
Sure, the screenshot comparison tools on our list address things like anti-aliasing and rendering artifacts. Blink-diff’s perceptual comparison is another example of how image comparison tools tackle the some of typical challenges of UI testing.
The problem is very few teams have the man-hours to address all of these issue with hand-written tests. So wouldn’t it be nice if a visual testing tool could minimize this overhead?
As a matter of fact, there are visual testing platforms that offer a smarter way for handling the everyday challenges of UI testing. Actually, I am working with a team that’s building an integrated visual testing platform of this kind. Let’s see what it can offer.
Screenster is an intelligent cloud-based platform that you can characterise as screenshot comparison 2.0.0.
Instead of merely capturing and contrasting screenshots, it generates visual baselines of the UI complete with DOM snapshots and lists of parents for every element. Instead of making you hand-code tests or tinker with auto-generated scripts, it records UX sessions and stores them as series of editable test steps. Instead of taking days to automate a UI test suit, it takes hours.
Below, you’ll find a glimpse of the smart functionality offered by Screenster.
Hand-coding your way around an ever-changing piece of a UI screenshot isn’t exactly a streamlined process. Besides, dealing with page coordinates is a real headache when you test complex responsive layouts.
With Screenster, excluding a dynamic UI region from future comparison is as simple as a couple of mouse clicks. What’s more, the platform will detect about 99% of dynamic content automatically during the first test run.
Timeouts are frustrating, and they contribute to the fragility of UI tests. Instead of making you deal with timeouts, Screenster will automatically determine the optimal waiting time for every test step. Yet again, a process that used to be tedious will no longer bother you.
The general philosophy with tools like Screenster is that your UI testing tool mustn’t slow you down. To get a glimpse of what you can expect from Screenster, check out the video below. In this clip, you’ll see that a basic test for an Ajax-heavy web application with rich UI can be recorded in under 3 minutes.
Okay, so how long does it actually take you to set up an automated screenshot tool? When working with Screenster, you deal with a readymade cloud solution. Sure, you’ll need to install a server, but you won’t have to tinker with dozens of separate modules and dependencies. One of the few things that comes as a separate plugin is the solution for CI support.
One more thing. In contrast to using one of the 13 tools mentioned in this post, Screenster doesn’t enforce the need of learning to code. Your manual QAs and business team can master the platform on the go — it’s really this simple. Doesn’t this sound like something you should definitely try?
As every developer knows, what works in the ideal scenario (a.k.a. your production environment) won’t necessarily work in the real world. That’s why you need tools like Retrace to help you quickly track down bugs and performance issues to keep things running smoothly.
Load testing, just one of many valuable testing methods you can use before release to ensure that your application is bug-free and runs seamlessly, is the process of testing whether an application can withstand the load of concurrent users, requests, and data volumes when in use. In other words, load testing is a must for determining if your applications can stand up to real-world use conditions.
There are many load testing tools available today for all kinds of applications and organization. In this article, we’ll look at 50 different load testing tools and highlight the key features of each of them.
