What you'll learn

Testing AI systems introduces a new set of challenges for software testers. This training explores the common risks you need to manage, and how testing approaches can be used when working with artificial intelligence and machine learning systems. You’ll learn how ML models influence system behaviour and how to validate AI-driven applications in modern software development environments.

Foundations of artificial intelligence

Build a practical understanding of artificial intelligence and how AI-enabled systems differ from traditional software. You’ll explore core AI technologies, development frameworks and common architectures used in modern applications. This foundation helps you recognise where AI introduces new behaviours and testing considerations.

Machine learning fundamentals

Learn how machine learning systems are developed and trained. You’ll work through core ML workflows, including how training and validation datasets are used, and see how data quality directly affects model performance. The module also explores how to select appropriate algorithms and tackle common challenges, so you can make more informed testing decisions.

Testing AI-based systems

Understand how testing strategies change when working with AI-driven applications. You’ll explore how AI systems are specified and validated across different test levels, with a focus on selecting and managing the right test data to support reliable outcomes. The course also introduces specialised techniques, such as adversarial and metamorphic testing, helping you apply the right approach to address the unique risks and behaviours of AI-based systems.

AI quality characteristics

AI-based systems introduce unique quality concerns. You’ll examine challenges such as bias, transparency and explainability, as well as the risks associated with probabilistic behaviour. You’ll learn how testers evaluate these characteristics to ensure AI-enabled systems remain reliable and trustworthy.
