Hello, testing community! A new wave of features and enhancements is here to make your testing job easier. 🚀
In October, we added support for Playwright accessibility testing, the ability to take responsive DOM screenshots in SmartUI and enhanced our UnderPass application for local testing. We also went live with many more such features and improvements in our other product offerings.
Let’s take a look!
With accessibility testing, you can ensure your websites and web apps are usable for everyone, including impaired users. In addition to Selenium and Cypress, TestMu AI now supports accessibility automation with Playwright, which lets you add accessibility checks to your Playwright tests. It means you can:
To enable the accessibility testing within your test suites, you need to set the accessibility: true in your configuration file. You can also specify other settings capabilities as shown below:
"accessibility": true, // Enable accessibility testing
"accessibility.wcagVersion": "wcag21a", // Specify WCAG version (e.g., WCAG 2.1 Level A)
"accessibility.bestPractice": false, // Exclude best practice issues from results
"accessibility.needsReview": true
TestMu AI SmartUI now allows you to capture responsive DOM screenshots using SmartUI SDK. Therefore, when your website changes the DOM based on viewport size or specific breakpoints, you can configure SmartUI SDK to adjust accordingly.
When using the SmartUI CLI, the SDK captures the DOM state at a specified viewport size in the test browser and then renders it across the browsers and resolutions you’ve set in your configuration file.
If your website changes DOM elements for different screen sizes, in that case, you need to make sure to resize the viewport in your test browser and capture a snapshot at each required width.
Refer to this documentation to get started with capturing responsive DOM screenshots.
In App Automation, you can now fetch app profiling metrics using API from your test sessions. You can integrate this API into your CI/CD pipelines or automation frameworks. With this, you can easily fetch real-time performance data, such as CPU usage, memory consumption, disk usage, and network activity.
To retrieve profiling details, you can simply send a request to the TestMu AI API using your TestMu AI Username and Access Key along with the relevant session ID. The response will include comprehensive metrics in JSON format, making it easy to integrate with other tools or reporting systems for further analysis.

We’ve added new features in Test Manager to make managing test cases easier and more organized.



UnderPass is a desktop application that lets you test local websites quickly without triggering the TestMu AI Tunnel from CLI. We’ve now further upgraded this UnderPass application from Electron v7 to the latest Electron v32. It can help you achieve better stability, performance, and compatibility across all operating systems.
Also, the UnderPass application is now available for European Union (EU) users.

Here are some new features that UnderPass application offers:
In the Test Analytics, we have optimized the date filtering for grouping tests. You can now group your test data Hourly, Daily, Weekly, and Monthly. It will help you perform in-depth time-based analysis.

Earlier this year, we went live with our first-ever certification for mobile automation, i.e., the Appium 101 Certification.
We have further expanded the TestMu AI Certifications pool by launching yet another certification for mobile automation testing. This time, it is Espresso 101 Certification.

Espresso 101 Certification is ideal for anyone wanting to level up their Android app testing skills. With this certification, you can get:
As you can see, October was a month packed with exciting updates. From certifications to advanced testing capabilities, we’re committed to empowering you to deliver high-quality websites and mobile apps!
Stay tuned for more innovative features and improvements coming your way!
