Our primer on modern QA automation tools – why you need them, what to look for, and some suggestions to kick off your shortlist.


What does a QA automation tool for a modern team look like? Doesn’t Selenium cut it anymore? Aren’t testing-related bottlenecks just a fact of 21st-century testing processes?
These are just a few of the questions we encounter when talking to teams across the industry about their testing needs. For the curious:
We’ve put together a quick primer on QA automation tools below – read on for the details.
Until this point, QA automation focused primarily on scripted tests that followed predefined paths through an application. These have generally been useful, but they were created for a very different software landscape.
Today's applications are dynamic, frequently updated, and often distributed across web, mobile, API, and cloud environments. This was not the case when Selenium first launched in 2004. The needs of modern software teams have moved beyond what established QA tools can provide for, for several reasons.
If your tool is using brittle selectors like CSS or XPath, even minor UI changes can break tests. In larger test suites, moving a button a few pixels to the left could break hundreds of tests.
And, as applications grow and you create more tests (without a proportional increase in the size of your engineering team), fixing these tests eats increasingly into time spent on other activities.
Modern DevOps and CI/CD pipelines have dramatically increased deployment frequency. And, increasing numbers of teams are accelerating their release cycle even further by using AI code creation tools.
Traditional testing approaches were not designed for this level of speed. As a result, teams often face a trade-off between speed and quality – we’re already seeing the effects of AI-generated code on production-level defects, for example.
Traditional QA tools only test scenarios that engineers explicitly define. It’s easy to miss user behaviors, edge cases, and complex workflows, which increases the risk of defects slipping through to production.
Traditional automation tools tell you what’s broken. They do not tell you why it’s broken. Your engineers still need to spend time investigating the defect from first principles.
If (like the majority of modern teams) your engineers run testing rather than outsourcing to an external QA team, this is a huge time burden – and it only gets bigger as your app grows.
Modern QA automation tools such as Momentic take a different approach to software testing automation. Rather than relying on rigid scripts and predefined rules, AI-driven features test with autonomy and intent. This means they can understand application behavior, adapt to changes, and help teams automate testing more efficiently.
Here’s how that supports modern teams more effectively than traditional tools:
Some features are more useful than others. Here are our top six:
There are various ways of automating testing without code (component/library-based tools, record-and-playback), but nothing is as efficient as describing what you want the test to do in plain English and letting the AI take care of the rest.
To really feel the benefits of an AI testing tool, self-healing features are a must-have. These will save you hours of engineering time per week.
A true AI native tool (rather than a traditional framework with some AI features bolted on) will offer agentic capability. This means that the AI can explore your app autonomously, flag gaps in coverage, and identify high-risk areas.
This doesn’t just save your engineers time. As your app grows and becomes more complex, it becomes easier to miss potential for unexpected user behavior and edge cases. Agentic AI provides a backstop, so that these don’t sneak through as you scale.
When tests fail, teams need quick answers. AI-powered diagnostics can identify likely causes, reduce troubleshooting time, and help engineers concentrate defect investigation on the most likely causes rather than starting from scratch each time.
Most tools will offer some form of CI/CD integration, but check how seamless it really is at the free trial/demo stage. You are implementing the technology of the future, not a clunky Oracle database from 2007. The ease of implementation should reflect this.
Look for compatibility with leading CI/CD platforms, source control systems, and developer workflows.
If you don’t have a native mobile app, chances are you will want one at some point in the future. At that point, your life will be much easier if your QA automation tool offers mobile-specific functionality, such as 1s emulator cold starts and app installs, seamless context switching, and embedded interactive previews.
Usual caveat: different organizations have different needs. Gather detailed requirements, check review sites, ask your network for their recommendations, and spend time on free trials/demos to find the right fit for you.

Hey, we back ourselves. If you want fast, intuitive AI testing features that save you time from day 1, get in touch.
Momentic’s AI-first features allow teams to create, execute, and maintain end-to-end tests with minimal manual effort. Natural language testing makes test creation significantly faster, while agentic AI functionality explores your app
Rather than converting instructions to code, Momentic interprets applications in a similar way to human testers. This powers the tool’s self-healing features, allowing tests to update with changes in the DOM.
Key features
Testim combines AI-driven automation with low-code test creation capabilities.
Its machine learning engine helps stabilize tests and reduce maintenance requirements while enabling teams to build automated workflows quickly.
The platform is particularly popular among organizations looking to accelerate test creation without abandoning customization options. Features are comprehensive, and the price tag reflects that, so this one is particularly popular with larger organizations.
Functionize focuses heavily on AI-powered test generation and maintenance.
Using natural language processing and machine learning, the platform helps teams create tests more efficiently and automatically adapt to application changes. Its cloud-based architecture also supports large-scale enterprise testing initiatives.
Mabl integrates testing directly into the development lifecycle and emphasizes continuous quality practices. The platform leverages machine learning to improve test reliability and identify issues earlier in the release process.
Mabl’s workflows are considered particularly engineer-friendly, making it a strong fit for DevOps-focused organizations.
Its developer-friendly workflow makes it a strong fit for DevOps-focused organizations.
Katalon combines traditional automation capabilities with growing AI-driven functionality. Its all-in-one testing platform supports web, mobile, desktop, and API testing, making it attractive to teams seeking broad coverage from a single solution.
If your team is big on visual UI testing, Applitools is worth looking at – either as a standalone tool or alongside broader automation frameworks to augment their visual quality assurance.
"We couldn’t reasonably scale with manual testing, and heavy scripted automation doesn’t solve the real problem – it just shifts the burden. Momentic was the only solution that helped us eliminate that burden.”
Glavin Wiechert (Founding AI Engineer, Coframe)
After implementing Momentic, Coframe now catches 80% of critical UI errors before deployment, all while speeding up end-to-end test creation by 70%.
For a tool that generates and deploys numerous website variants that can be tripped up by a single bug, Momentic has been invaluable in guaranteeing quality and removing bottlenecks.
