In the span of only a few months, AI has reshaped the landscape of almost every industry around the world in both positive and negative ways. Indeed, there is still a lot of room for improvement for this groundbreaking technology, but if businesses don’t embrace it, they’re sure to be left behind. In the QA industry, “AI testing” will become the norm in the next few years, bringing incredible advancements in the way we think and do software testing.
In this article, we’ll explore the concept of AI testing in-depth, see how AI can optimize testing, and share the pioneering AI testing tools that you can leverage to transform your QA workflows.
Before diving into the concept of AI testing, we must first have a common understanding of Artificial Intelligence (AI). AI has become a buzzword recently after the introduction of ChatGPT - a revolutionizing chatbot. So, what is AI?
AI can be defined as the simulation of human intelligence via machines that are programmed to perform tasks that require advanced cognitive abilities, such as data analysis, decision-making, learning, and adapting to new information. In a way, basic programming can only instruct computers to strictly perform a limited set of tasks, whereas AI systems have a certain degree of autonomy to them.
AI testing is the process of evaluating the functionality, performance, and reliability of a system with the help of AI. It still involves the same core techniques used in traditional software testing, but these techniques have been drastically improved by AI technology.
When talking about traditional software testing, we usually think of a hybrid testing approach: partially automated and partially manual. Testers leverage automation testing tools to perform repetitive test cases so that they can focus more on tasks that require human reasoning such as decision-making and planning.
Once incorporated with AI, these tools will be able to assist testers in those advanced human reasoning tasks. It will bring the scalability of these tools to an even higher level, so testers can gradually move on to more strategic tasks. No longer just “testing tools”, they are AI-powered testing tools.

AI testing can also be understood as testing for AI-based systems, or “testing for AI”. These AI systems incorporate various AI techniques, including machine learning, natural language processing (NLP), computer vision, deep learning, and expert systems, to process a tremendous amount of data to recognize patterns and make intelligent decisions.
Testing AI systems is similar to testing any other systems, and involves a six-step process from requirement analysis to test cycle closure. The major difference is that AI systems tend to also display extremely complex, diverse, and highly probabilistic behaviors. The number of scenarios to be tested is huge, and therefore
data-driven testing is usually the most common approach.
According to the State of Software Quality Report 2024, AI is most commonly applied for test case generation, both in manual testing (50% respondents agreed) and automation testing (37%). Test data generation is another domain where AI shines through, with 36%.

Here are some more benefits of adopting AI in QA:
1. AI Enables Faster and Smarter Test Creation
AI can help QA testers generate test scripts both more quickly and intelligently. Usually these automated test scripts must be developed by a tester with engineering expertise using a test automation framework like Selenium; after that they have to be continuously maintained as changes are made to the source code. However, we can now provide a prompt in plain language that instructs the AI to create a test for a specific scenario, and it’ll write one in just seconds for you.
The trick is to know problem formulation, i.e., clearly defining the focus, scope, and boundaries of the test for the AI to generate new tests. Over time, as the AI learns more about the user behavior in your application under test (AUT), it can slowly adapt its test generation to fit with your specific business needs. It identifies your testing patterns by reviewing requirements, existing test cases, as well as logged test cases, to suggest the most relevant test cases for you.
2. AI Can Quickly Generate Test Data for Data-Driven Testing
In certain cases, to test comprehensively you would need a large volume of data, or a huge number of data combination inputs.
For example, testing the search functionality for thousands of different queries on existing products and locations of an e-commerce website. Instead of creating those data points from scratch or spending hours finding a suitable dataset on the internet, you can simply instruct the AI to generate a dataset for you. The high level of customization allows you to prepare mock test data for almost any scenarios you can think of.

3. AI Makes Test Maintenance Effortless
Software and websites are updated all the time, especially in organizations that employ the Agile testing methodology. Test scripts written to test an element can quickly fail when the code is updated. For example, if we wrote a test to click on a button with the ID "login-button," changing this ID for any reason will cause the test to fail. Having to update a large number of test cases every time code changes occur (quite frequently) is a time-consuming process.
With the coding part now slightly offloaded to AI, testers are left with the daunting task of test maintenance, which can also be addressed easily with AI. AI can simply regenerate the test scripts each time a code change occurs. For example, if it can’t find an object with its current locator, the AI will attempt to use another locator and continue to run the test. This is known as the Self healing mechanism.
4. AI Enhances Visual Testing
Visual testing used to be quite a formidable task as human testers have to use their own eyes to spot visual differences between the UI-before-deployment and the UI-after-deployment. Visual testing tools can indeed identify visual changes better, but they can’t distinguish changes that affect the users and changes that do not. AI-powered visual testing tools, on the other hand, take that into consideration, and therefore can identify bugs more accurately.

ChatGPT is undoubtedly shaking up the AI world, and the tremendous advantages it can bring to software testers can’t be ignored. However, the trick to using ChatGPT is to master prompt engineering, and at a higher level, problem decomposition. With certain testing bottlenecks, we can now consider how a tool like ChatGPT can assist us, and then come up with a methodological solution that can be converted into a prompt. GPT won’t test for you, but it can be instructed to take over the more repetitive and mundane tasks, while QA teams move to the strategic planning areas.
AI will not render testers obsolete, and it is essential for QA engineers to familiarize themselves with AI and its potential to enhance software development. From a job market perspective, the rise of AI testing will actually intensify the demand for highly skilled and specialized QA experts that know AI prompt engineering to utilize vast volume input data to make decisions and reach conclusions faster.
