AI in Quality Assurance: How AI is Transforming Future of Quality Assurance

Key Takeaways

• The global market for AI-enabled testing has reached around USD 500 million.
• AI can help QA achieve better automation, integration with Gen AI, and predictions for quality failures.
• It offers benefits like resource optimization, quicker bug detection, and quality engineering.
• QA teams might face challenges regarding edge cases, transparency, and security while implementing AI.

“We understand human mental processes only slightly better than a fish understands swimming.”

‍John McCarthy, an American computer scientist, stated this belief more than 40 years ago. Surely, his commitment to understanding the human mental process led him to ideate one of the most revolutionary ideas in computer science—artificial Intelligence (AI). Since then, AI has helped us develop software, utilize it to streamline our business offerings and maintain another essential aspect of digital ecosystems—quality assurance.

QA has come a long way from manual testing during the waterfall times to continuous testing with DevOps and CI/CD. Our inclination towards automation, collaborative operations, and product security has led us to outsource our QA to managed testing services. This shows that we are past mere performance, functionality, and UI consistency checkpoints with our modern software applications. 

Thanks to AI, QA experts can now evaluate more nuanced software aspects, including scalability, security, data integrity, interoperability, and more. That is why the current market evaluation for AI in software testing, as per reports, is around USD 500 million. Therefore, it is imperative that businesses now engage with AI for the gifts it brings to software quality assurance.

Role of AI in Quality Assurance

As our dependence on software has grown across industries, our quality parameters have also evolved. We now want our applications to be more adaptive to changing conditions, synchronous for distributed environments, and compliant with varying geographical regulations. In addition, rising cyberattacks mandate that we “quality check” applications and platforms for security vulnerabilities.

AI helps us expand the efforts essential for such a level of quality standards. Here’s the role for AI that you should seek while looking for QA consulting in the future:

• Enabler of Automation: One of the most traditional utilities associated with AI is its ability to automate. In the case of QA, AI can help with generative test cases automatically while also enabling autonomy for different software testing types like unit testing, functional testing, etc. With assistance from various machine learning algorithms, it can analyze user stories and understand different checkpoints that make sense for any software from the quality point of view.
• Regulator of Continuous Testing: AI tools can easily integrate with CI/CD pipelines to make continuous testing smoother and more aligned with a business's QA needs. They can help trigger tests that automatically work in tandem with the ongoing development lifecycle and offer quality-related feedback in real-time.
• Mediator for Generative AI: Integrating AI with the QA process opens up the QA strategies for engaging with Generative AI as well. This would help improve test planning, test coverage, and an overall envisioning of different test scenarios. Once Generative AI gets involved in the QA process, the software becomes more reliable on all quality fronts.
• Foreseer of Quality Failures: AI cannot only help evaluate all the quality checkpoints but also predict how software quality might fall short. Its ability to analyze historical data can help QA teams with this predictive capability. Only AI can help preemptively identify high-risk areas and potential chances of quality bugs.

Benefits of AI in QA

Integration of AI can make the entire QA process more productive, precise, and personalized as per business requirements. This is why AI-driven software testing is gaining appeal. Here are some of the essential benefits it can offer:

‍

• Optimizing QA Resources: The more complex the software, the more resource-intensive its QA process. Take penetration testing, for instance. It can very likely take weeks before any meaningful results are reached. AI can help optimize resource utilization for QA by offering features like automated QA testing, predictive analytics, customized test plans, and more.
• Streamlining Bug Detection: AI can bring technologies like neural networks, natural language processing, and more that can help enhance the entire bug-finding process. AI tools can help understand user stories and generate test cases accordingly. They can also help analyze the quality requirement and plan for more nuanced QA that might not be possible for non-AI tools.
• Enabling Quality Engineering: AI can broaden the scope of QA and accommodate other quality-oriented processes, such as data quality control, workflow consistency, and more. If integrated with generative AI, it can refine the QE process by self-generating test scenarios that cater to more nuanced traceability matrices.
• Integration with CI/CD: AI can help enable continuous testing so smoothly throughout the CI/CD pipeline by preparing automated test scripts that won’t disrupt the other parts of the cycle. AI-enabled test scripts also ensure faster testing and quicker release without compromising quality and performance.

Challenges of AI in Quality Assurance

‍

Any apprehensions about allowing AI to take over your QA apparatus stem from the broader concerns about AI in general. The potential risks posed by adopting AI regarding accuracy and security lead to different challenges that object to the AI and QA marriage.

• Handling Edge Cases: Much quality assurance revolves around efficiently handling edge cases, which are rare but can have a vast impact on the software product’s quality. Such cases need intuitive oversight, which AI has not yet been able to achieve.
• Critical Errors: AI heavily depends on the quality of the training data. If the AI tools being used need to be more sophisticated to understand the nuance of complex business use cases, this can lead to oversight of critical bugs in quality and security.
• Security and Data Privacy: Access to large datasets by AI tools can lead to leaks in sensitive business data that can be easily targeted by cyber threat actors. AI can also oversee or misinterpret some compliance regulations, leading to loopholes in data privacy and access control.
• Cognitive Bias: More often than not, AI-driven operations run on training data that comes from a very limited demographic (even when coming in a sizeable volume). This creates a lack of diversity and, therefore, a cognitive bias in its operation that can affect the test case generation and proactive assessments for QA teams.
• Transparency: Another concern with AI is its “hidden ways.” The different factors that help operate AI in a particular way are much beyond the comprehension of a non-AI expert. This can make it difficult for QA teams to understand why a particular element in the software is tagged as a bug without understanding the reasoning AI took for that conclusion.
• Limited Test Coverage: The data offered to train AI needs to be highly diverse. If this criteria is not met, AI can leave a lot of demographics and business use cases from its QA coverage leading to incomplete or skewed results in QA drives.

Best Practices for Implementing AI in QA

Certain practices must be included in implementing AI in quality assurance to mitigate the above challenges. These challenges would help the QA teams ensure more business-oriented and customer-centric processes to ensure product quality.

• Prioritizing Security: The QA process must be more sensitive toward data privacy, access control, network exposure, etc. The AI models, therefore, will have to be trained on encrypted data, role-based access, and multi-layer protection for sensitive data. Separate security protocols for AI integration must be adapted and regularly updated.
• Rigorously Tested AI Models: Validating AI models before deploying them into the QA ecosystems is also an essential practice. QA teams can continuously monitor the AI tools for their accuracy, effectiveness, and alignment with the software's evolving quality needs.
• Co-pilot with other QA processes: A strategic approach towards adopting AI for QA would require enough space for non-AI QA resources to work in tandem with the AI tools. This would ensure a balanced testing environment for all QA goals and would allow the AI resources enough time to evolve from their initial shortcomings.
• Explainable AI: Implementing explainable AI or XAI is also highly recommended to keep the decision-making process transparent. This would build more trust towards AI-generated QA results and would enable teams to better deal with any anomalies.
