Martin Kowaleski, Director of Sales Engineering at Applitools led a powerful session at MTES 2024 illustrating the power of Visual AI automation testing. He gave a brief overview of visual testing and its importance, then provided an in-depth demonstration of how Kobiton and Applitools integrate to empower testers by automating visual testing.
Kowaleski had been in the industry for over 20 years. He has a background in dynamic storytelling, problem solving, and is a proven pre-sales leader in technical solutions achieving real business outcomes.
Applitools sets the industry standard for AI-powered test automation, embedding AI throughout the testing lifecycle. The Applitools Intelligent Testing Platform is remarkably intuitive, enabling every team member—from design and development to QA, operations, marketing, and product teams—to contribute to quality assurance, regardless of coding expertise. With Applitools, companies can accelerate their testing processes, perform comprehensive quality checks, and ensure superior product delivery through proactive, continuous testing.
Visual testing, as defined by Martin, is “the process of validating all the visual aspects of an application’s UI on all platforms.” This testing extends beyond Appium, Espresso, or XCUI. It ensures that the content, images, and buttons appear correctly.
Since functional testing can balloon test scripts if you use it to validate the size and position of visual elements, visual testing can be useful for developers. There are two forms of visual testing: manual and automated. Each has advantages and disadvantages; you must decide what works best for your system.
Manual testing consumes a lot of time and effort. This form of testing is done by comparing two screenshots: a baseline and the latest version of the app. Each screen must be tested individually on each device and with each unique screen orientation. Kowaleski did the math and to conduct a manual test for one screen on your app, there would be 40 different screen orientations to test using Android and IOS operating systems. That is a lot of testing!
Automated visual testing can be a good option to get your whole team involved in the testing process. This form of testing compares the visual elements of each screen through Appium, XCUI, Espresso, or Webdriver. By automating your visual testing, your team can reap these benefits:
There are two types of visual testing: Pixel comparison and Visual AI. Pixel comparison involves taking bitmap screenshots of the new screen and comparing them to a baseline bitmap to detect subtle differences. However, it has limitations. It cannot accurately test overlaps, affecting dynamic content testing. Additionally, it struggles with mobile apps due to dynamic elements like date, time, battery status, and display settings, which can result in false positives.
Visual AI testing uses algorithms to test for differences. Visual AI can be used in both static and dynamic environments. There are many use cases Visual AI testing covers that pixel does not. These include:
Visual AI in native mobile automation offers more testing coverage for less work. It is able to test a range of visual elements on OS, browser, screen orientation, and resolution combinations.
Kowaleski gave an example of pixel comparison vs Visual AI testing on an e-commerce app. The pixel comparison would have failed the test because users sort products differently, and each time a user searches for a product, the products show up differently. In this case, Visual AI testing would be a better option as it tests using an algorithm.
Kowaleski demonstrated his workflow through a manual testing session on the Kobiton platform. Watch the full demo here, but in the meantime, here is a quick summary:
Kobtion’s integration with Applitools allows for greater collaboration within the testing environment. Martin Kowaleski verified that Applitools and Kobiton’s integration is a
“Powerful capability to run a mixed session for Kobiton.”
