The closing decision on which approach to use relies on the vision of the whole organization and the team. Whichever you select, there are generally 5 areas an AI/ML system can provide the most:
Automated Smart Test Case Generation
ChatGPT has significantly influenced the software engineering field, demanding newcomers to improve their skills to meet growing requirements. ChatGPT can be used to write test cases in the software testing field, but it’s not a one-size-fits-all solution. Traditional automated test scripts require constant maintenance to understand updated code, which is challenging for automation testers in the dynamic, agile environment. The integration of AI/ML in software testing offers a simple language prompts that help crafting tests for precise scenarios and accelerate test maintenance work.
Test Case Recommendation
Machine Learning is a powerful tool that can learn from data and make forecasts without being programmed for each scenario. As time passes, AI learns about user usage and make test plans to align with business demands. For eCommerce websites with thousands of products and continuous updates, Machine Learning analyzes user engagement data, i.e., product views, checkout steps, and cart abandonment. As the AI collects and evaluates this data, it identifies patterns and patterns, allowing it to customize testing to imitate real user engagement. The AI then focuses on testing the checkout process and product connections. As more AI is utilized, it improves, and in the future, AI/ML could become a predictive analytics engine capable of identifying potential issues based on learned patterns. This helps QA managers and Team Leaders make more informed decisions.
Test Data Generation
Comprehensive testing for global eCommerce websites requires a large volume of data with various inputs. This can be challenging due to differences in shipping fees, package weight, geographic zone, distance, carrier selection, coupons, and extra charges. AI/ML can help generate a mock data set for testing without collecting real-life data. By commanding the AI to provide addresses in regions, detailed information like shipping weight, time zones, and additional fees can be incorporated, saving time and effort.
Test Maintenance for Regression Testing
Agile testing often encounters updates in software and websites, causing test scripts to fail due to code changes. This can be time-consuming and a common issue during regression testing sessions. To address this, AI can automatically regulate test scripts when code changes occur, using a Self-Healing Mechanism. Reducing the load on testers and ensuring tests continue running smoothly even when code changes help maintain the integrity of software and websites.
Defect Prediction
AI and ML models can assess historical defect data, code complexity and susceptibilities, and other significant criteria to classify possible matters in existing software releases. Testers might use these predictions to preventively aim certain areas for testing, reducing the risk of flaws reaching production.
Visual Testing
Visual testing is a challenging task for software testers. It includes comparing screenshots of the user interface before and after launch. Computers often identify minor visual variations as visual bugs, which don’t significantly impact user experience. Different computers extract images differently, making them technically different but not visually clear. Some UI elements, like the cart icon on eCommerce websites, change frequently, making test scripts mistake visual differences for bugs. AI has addressed this issue by omitting certain zones and identifying rational differences between screenshots, providing AI the competence to view visual testing from a more human perspective, allowing for more effective integration into QA teams. AI/ML has advanced extensively in recent years, delivering numerous potential applications in various situations.
