Visual Testing: A Complete Guide
Brittney Lawrence
It was my first month as Kobiton’s CTO in January 2018, and I found myself right at the forefront of what felt like an AI awakening in software testing. I remember attending a bustling conference where Jason Arbon passionately spoke about his startup, test.ai, igniting a spark of excitement in me. Just a few booths down, Moshe Milman from Applitools was dazzling the crowd with live demonstrations of AI-powered visual testing. Meanwhile, competitors like Bitbar were making bold claims about their AI’s ability to automatically test mobile apps—simply upload your app, and their AI would navigate through it, hunting down bugs like a digital detective. It all sounded like magic! But reality quickly checked my enthusiasm when their depth-first navigation didn’t know when to stop, leaving me staring at a timeout failure message hours later. It was a humbling reminder that while AI holds immense promise, the path to flawless automation is still being paved.
Here we are, 7 years later, and while AI in software testing has made undeniable strides, it’s clear we’re still grappling with some significant challenges. AI Testing Agents are emerging with bold promises—automating routine test cases, identifying bugs with lightning speed, and simplifying once-tedious workflows. But let’s cut through the hype: many of these so-called agents are little more than fancy wrappers around tools like ChatGPT. They often fall short when it comes to true adaptability and nuanced understanding, leaving human testers to step in for unexpected scenarios or complex user flows. The initial thrill of endless AI potential has matured into a more cautious perspective: while the possibilities are exciting, we’re still miles away from achieving Artificial General Test Intelligence (AGTI). In this guide, we’ll dive into the real limitations holding AI Testing Agents back and explore how the breakthroughs anticipated in 2025 could help us move closer to realizing their full potential. Stick with me—we’ve got plenty to uncover.
So grab a cozy seat and let’s unravel the fascinating world of AI Testing Agents. By the end, you’ll not only understand the jargon but have a sense of which AI testing strategies might give your dev or QA team a competitive edge.
Let’s start by tackling the most pressing question of all: what on Earth is an AI Testing Agent? You may already be familiar with AI in some capacity: maybe you’ve used chatbots on retail websites or tried out text-to-image generation tools. But the notion of an “AI Testing Agent” is more specialized.
An AI Testing Agent is essentially a form of artificial intelligence dedicated to software testing tasks. Think of it as a “digital coworker” with the power to examine your application, spot functional, performance, and other issues, and even adapt testing scenarios on the fly—just like an experienced software tester might do manually. But don’t worry, this digital teammate isn’t here to replace testers; instead, it’s designed to handle the tedious, repetitive tasks so human testers can focus on the creative, high-value work they do best.
To understand AI Testing Agents better, it helps to zoom out a little and see them within the broader AI ecosystem. AI is a blanket term for computational algorithms and models that simulate human intelligence, typically featuring traits like learning and problem-solving. Inside this big tent, we have:
So, if the big umbrella is AI and each of those bullet points are specialized skill sets, AI Testing Agents fall under the subset of AI specialized in software testing. They combine various AI techniques to automate, optimize, and even strategize the testing process.
Let’s break it down. Imagine you’re testing a mobile application. Normally, you’d write test scripts for a framework like Selenium or Appium, or you’d rely on manual testers to navigate through the app step by step. The AI Testing Agent is supposed to change the game by automating much of this process, but it’s important to understand what makes it truly agentic versus simply an application of AI.
This is where the AI uses techniques like computer vision or natural language processing to collect information about your application—its UI elements, user flows, and possible interactions. While impressive, this is just standard AI doing what it’s trained to do: recognize patterns and extract details.
Here, the AI creates a computational model of the application’s states and transitions—essentially mapping out how users might navigate through the app. This phase lays the groundwork for testing but doesn’t yet involve decision-making or autonomy. It’s still a traditional application of AI. Kobiton’s Appium Script Generation is an example of leveraging Generative AI using Model Building.
This is where the agent part comes into play. Unlike basic AI, which operates within predefined parameters, an agent actively decides what tasks to perform based on its understanding of the app. It might determine, for example, that clicking a particular button, entering varied data, or testing edge cases will likely reveal critical bugs. This decision-making and adaptability elevate it beyond simple automation. Kobiton’s Scriptless Automation listens to tester’s actions and learns how to test mobile applications.
The real promise of AI Testing Agents lies in their ability to go beyond simply flagging failures. In theory, a true agent learns from its testing results, refining its approach to improve test coverage and accuracy over time. This continuous feedback loop—analyzing outcomes, updating strategies, and autonomously evolving—is what should set AI Testing Agents apart. However, this promise remains largely unfulfilled. While we see incremental progress, most current implementations fall short of the adaptability and independent reasoning needed to approach Artificial General Test Intelligence (AGTI). True AGTI would enable agents to learn complex testing strategies across diverse applications and environments without human intervention—a capability we’re still striving to achieve.
If you’ve hung around the tech world for more than five minutes, you’ve probably bumped into the buzz around AI agents—especially in software testing. Everyone’s touting them as the next big thing. But let’s set the record straight: many so-called “AI agents” are actually just AI workflows or automations wearing a trendy buzzword costume.
And while that might sound like a minor technicality, it’s actually a big deal—especially if you’re looking to harness the genuine power of AI in your testing pipeline. Mixing up real AI agents with simpler automations can lead to inflated promises, half-baked results, and a whole lot of frustration. So let’s dig into the differences and how they shape the way you approach your testing strategy.
In the realm of software testing, we often see tools described as “agents” that promise magical, autonomous results—like discovering hidden bugs at lightning speed. But scratch the surface, and you might find these “agents” are really just orchestrated scripts, advanced automations, or linear AI workflows.
When you mistake an AI workflow for a true AI agent, you risk setting unrealistic expectations. For instance, a fancy script that runs regression tests based on a set schedule might be powerful, but it’s not going to adapt, learn new testing strategies on the fly, or pivot when the code changes drastically. That’s where the concept of “agency” really comes into play.
Let’s break down each category in the context of testing, so you know exactly what you’re dealing with.
Automations handle predefined, rule-based tasks—and do them without human intervention. They’re straightforward, deterministic, and extremely efficient for repetitive testing scenarios.
Example in Testing
You might have a script that automatically checks your login page with a handful of valid and invalid credentials. It’s dependable and runs exactly as programmed, but it has zero ability to test new conditions or “think” outside its coded rules.
Strengths
Weaknesses
AI Workflows combine deterministic processes (like a typical automation pipeline) with some AI capability—say, a language model that writes test scripts or flags potential test gaps. They’re more flexible than plain automations but still bound by overall task-specific rules and structure.
Example in Testing
Think of a workflow that automatically runs a suite of regression tests whenever you push new code, then uses a language model (like ChatGPT) to create a brief report highlighting failures or suspicious patterns. It’s more “intelligent” than a simple script, but it’s still following a prearranged path.
Strengths
Weaknesses
Real AI agents go beyond scripted flows and rigid logic. They’re autonomous, adaptive, and capable of non-deterministic tasks—which means they can learn from feedback, pivot strategies, and adjust to new or unexpected conditions, much like a human tester might.
Example in Testing
Imagine an AI testing agent that not only executes a test suite but also learns that certain areas of your application (like payment processing) are notoriously buggy. It then devotes extra energy to testing those components, tries new inputs it hasn’t seen before, and refines its own strategy based on user behavior trends. That’s true adaptability.
Strengths
Weaknesses
If you’re evaluating a new testing tool, or you’re building one in-house, here are the core qualities that set real AI agents apart:
If the answer to most of these questions is “no,” you might be dealing with an AI workflow (still valuable!) rather than a full-fledged agent.
This next question can leave people scratching their heads, especially if they just stepped into the realm of AI in software QA. The phrases “AI Testing Agent” and “Testing AI Agents” sound suspiciously similar, right? Let’s break down both:
Both are important, but they’re different tasks requiring different sets of data, tools, and expertise.
A lot of folks get these two concepts tangled because of how they’re named. If you see a reference to an “AI agent in testing,” it might take a moment to figure out which side of the coin you’re dealing with. Just remember:
Understanding the difference ensures that your approach—tools, objectives, metrics—are aligned with your goals. If you’re wanting to integrate more automation into your QA, you might be searching for an “AI Testing Agent.” If you’re building a brand-new AI product and want to ensure it behaves responsibly, you’re going to be “Testing AI Agents.”
If you’ve been following the AI conversation in natural language processing (NLP) tools—and particularly large language models (LLMs)—you may have heard the term “Retrieval Augmented Generation” (RAG). Though it sounds a bit fancy and might conjure images of robot librarians or futuristic data archives, RAG is actually quite straightforward once you know the basics.
Retrieval Augmented Generation is a technique that combines two major steps:
So how does something from the realm of advanced NLP tie back to software testing? Let’s break it down with some real-world scenarios that show the promise of Retrieval Augmented Generation (RAG) in AI Testing Agents:
Because RAG integrates these two critical functions—accessing a rich knowledge base (retrieval) and generating contextually relevant outputs (NLP-based generation)—it significantly enhances the accuracy and relevance of AI Testing Agents. While we’re not yet at the point of fully realizing this potential, advancements like these are paving the way for tools that could fundamentally reshape software testing by providing detailed, context-aware insights that augment human expertise.
If you’ve spent any time in software development or QA, you’ve likely wrestled with the same challenges: looming deadlines, ambiguous requirements, and that seemingly endless backlog of regression tests. It’s the hydra of software testing—fix one bug, and three more rear their ugly heads. While AI Testing Agents won’t replace the intuitive and creative skills of manual testers or automation engineers, they can ease the load by handling repetitive and data-intensive tasks, freeing your team to focus on the strategic, nuanced work that drives quality.
Let’s explore five key areas where AI Testing Agents, powered by emerging technologies, are reshaping software testing—and where they’re still working toward their full potential.
Time is always at a premium, and development teams are constantly under pressure to ship features or fix bugs before the next sprint. While traditional automation tools like Appium allow for parallel test execution, AI Testing Agents take this a step further by introducing intelligent prioritization and adaptive coverage. Through Kobiton’s partnership with Appsurify, AI Testing Agents can analyze recent code changes and focus testing efforts exclusively on the functionality impacted by those changes. For example, in a retail application, instead of running the entire suite of checkout tests, the agent might prioritize testing updates to the payment gateway or promotional code functionality if those areas were modified in the latest commit.
By leveraging this targeted approach, teams can achieve faster execution times and uncover critical issues more efficiently. This integration ensures that feedback is not only rapid but also highly relevant, allowing teams to address high-risk areas with confidence while maintaining the agility required in modern DevOps cycles.
Human testers are brilliant at spotting patterns and creatively exploring applications, but even the best testers can get tired or overlook edge cases. AI Testing Agents are relentless. They methodically test every button, input field, and workflow, ensuring no stone is left unturned. Strategies like coverage-based exploration enable these agents to focus on parts of the code that are often ignored, such as rarely used features or obscure configurations.
For example, Kobiton has used its Performance Validations to benchmark the Delta mobile app against competitors, ensuring key performance metrics like load time and responsiveness meet or exceed user expectations. By continuously comparing application performance to a growing knowledge base, AI Testing Agents help identify subtle issues that might otherwise escape detection.
One of the most exciting promises of AI Testing Agents is their ability to adapt and learn. If an agent detects recurring issues—say, frequent failures in payment processing—it can generate new test scenarios targeting those vulnerabilities. Over time, the agent’s testing strategy evolves, making the suite smarter and more aligned with the application’s needs.
This adaptability could see significant advances with the introduction of Meta’s Large Concept Model (LCM). Unlike traditional Large Language Models (LLMs), LCM operates in a high-dimensional semantic space, allowing it to grasp abstract ideas and actions across languages and modalities. Applied to testing, this could mean agents capable of understanding complex workflows without being tied to specific programming languages or UI frameworks. For example, an agent using LCM could test a multilingual e-commerce platform, identifying gaps in user experience across languages and modalities in a single testing cycle.
If you’ve ever spent a sprint fixing broken test scripts after a UI redesign, you know how tedious and time-consuming maintenance can be. AI Testing Agents can alleviate this pain point by re-mapping workflows dynamically. When an application’s structure changes, the agent updates its understanding without requiring manual intervention, reducing maintenance costs and effort.
With tools like OpenAI’s Reinforcement Fine-Tuning (RFT) and Kobiton’s Self-Healing Automation this could become even more efficient. By learning from minimal examples, the agent can quickly adapt to new workflows or components, ensuring that your test suite remains robust and relevant as your application evolves. For instance, after a major UI update to a fintech app, an AI Testing Agent could identify and adjust broken test paths within hours instead of days.
AI Testing Agents aren’t just for the QA team—they improve communication across the entire product pipeline. Continuous testing powered by AI provides real-time insights for developers, helps product managers track feature stability, and offers executives early visibility into potential release risks.
Kobiton’s Performance Validations demonstrate this beautifully. By integrating with Jira, AI Testing Agents can pull in known bugs and determine whether to link a test failure to an existing issue or create a new one. This streamlined workflow ensures that everyone—developers, testers, and stakeholders—stays on the same page, reducing the friction that often slows down software delivery.
AI Testing Agents offer a glimpse into the future of software testing—one where tedious tasks are automated, and humans focus on creativity, strategy, and innovation. But let’s not oversell their capabilities just yet. While technologies like RFT and LCM bring us closer to the dream of smarter, more autonomous agents, many challenges remain. Current AI Testing Agents excel at predefined tasks and structured workflows but still struggle with truly nuanced, domain-specific reasoning.
The breakthroughs expected in 2025 hold immense promise, but we’re not there yet. By understanding both the potential and limitations of today’s tools, we can better prepare for the transformative changes on the horizon. Until then, AI Testing Agents are here to help—not replace—your team, empowering them to focus on what they do best: ensuring your users get the best possible experience.
It’s one thing to talk about how AI Testing Agents fit into today’s software development ecosystem, but let’s face it: technology moves at a breakneck pace. To future-proof your strategy, you want to know where AI Testing Agents might be heading. So let’s close out with a little bit of informed speculation (mixed with a dash of hope) about how AI Testing Agents will improve by 2025.
By 2025, we can expect AI Testing Agents to have better “understanding” of applications, thanks to more sophisticated machine learning and natural language processing. Instead of just iterating through user paths, they’ll parse system requirements, user stories, Figma designs, and developer notes to create tests that are context-aware. You might see them referencing design guidelines or coding best practices to automatically generate new test cases, even before your team explicitly tells them to do so.
We’ve already seen testing move from a post-development activity to a continuous integration and continuous delivery (CI/CD) pipeline. By 2025, AI Testing Agents will likely become first-class citizens within these pipelines. They’ll automatically coordinate with version control systems, container orchestration (think Docker, Kubernetes), and CI/CD tools to spin up ephemeral environments and run massive test suites on demand. They’ll also collaborate in real time with other AI-driven tools (like code linting bots and security scanning agents).
One of the big constraints in software testing is always time and resources. You can’t test everything, so you have to pick and choose. Future AI Testing Agents will be able to assess risk in real time—for example, factoring in the complexity of the code change, recent bug history, or even developer skill levels (some devs might be more prone to certain errors!) From there, they’ll prioritize tests that are statistically more likely to reveal defects. This dynamic test prioritization ensures that you spend your limited test resources more effectively.
As AI Testing Agents become more autonomous, they’ll go beyond just reporting “Hey, something broke.” They’ll begin to pinpoint root causes, perhaps even offering solutions like “There is likely a null pointer exception in the PaymentService
class around line 52.” Over time, these AI Agents may even propose or implement bug fixes automatically—what we might call “self-healing” test scripts. Some frameworks already have partial versions of this in place, but we can expect it to be far more robust and widespread by 2025.
With the growing spotlight on AI ethics—especially around privacy, transparency, and fairness—AI Testing Agents may incorporate these values into the testing process. They’ll systematically check for issues like data leakage, compliance with regulations (GDPR, HIPAA, etc.), or hidden biases in the user experience. So not only will your code be functional; it’ll also be more likely to respect user data and meet ethical standards.
Picture multiple specialized AI Testing Agents, each with its own strengths—one focuses on security vulnerabilities, another on performance bottlenecks, and a third on UI/UX flows. By 2025, we might see collaborative AI swarms that share data and insights in real time. This synergy could lead to test coverage that’s not just broad, but also deeply interconnected, catching multi-dimensional issues that single-purpose tools might overlook.
As AI Testing Agents improve, we can expect the user experience around them to become more accessible. No-code or low-code interfaces might let non-technical team members easily configure and launch AI-driven tests. This democratization of AI means smaller companies and teams without dedicated data scientists can still reap the benefits of advanced test automation.
With the rise of agile methodologies, DevOps practices, and an ever-accelerating feature release cycle, software testing has become a linchpin in modern software development. AI Testing Agents represent the next big leap. They’re not a panacea that makes human expertise obsolete—but they are powerful allies that can shoulder the burden of repetitive testing, adapt to new challenges, and even harness advanced NLP techniques like retrieval augmented generation to continuously refine their strategies.
To recap:
Whether you’re a QA lead at a large enterprise or a lean startup founder wearing multiple hats, AI Testing Agents are definitely something to keep on your radar (if they aren’t already part of your strategy). The future of software testing isn’t just about automating yesterday’s scripts; it’s about embracing AI to explore new frontiers and deliver bulletproof applications in record time.
Sure, AI still has a long way to go, and it’s not without its challenges, from model bias to the need for high-quality training data. But if you’re reading this, you’re already ahead of the curve—because knowledge is half the battle, and you’re equipping yourself with the insights you need to make informed decisions about the next generation of software testing tools.
Thanks for reading, and here’s to building better software—together with AI. If you have questions or stories about your own experiences integrating AI Testing Agents into your workflow, don’t hesitate to join the conversation. The more we share, the smarter we all become. And remember: the best testers keep learning, iterating, and adapting—just like the very AI agents that are set to revolutionize our industry.
