Reliable automation requires trust. Learn how PowerShell classes improve testability, how to write effective Pester tests, and why testing business logic, validation, and object behaviour can dramatically reduce the risk of production failures.

Classes are only the beginning. Learn how to organise domain objects, service classes, configuration, and reporting into reusable automation frameworks that scale beyond individual scripts without becoming overly complicated or difficult to maintain.

Explore how inheritance can reduce duplication and improve code reuse, while also learning why deep class hierarchies often become a liability. Understand when to use inheritance, when to prefer composition, and how to keep your object model simple and practical.

Refactor a traditional server health-check script into a practical PowerShell class. Discover constructors, methods, encapsulation, and object behaviour through a realistic example that demonstrates how classes can turn sprawling scripts into maintainable automation solutions.

PowerShell classes are not about making scripts look like C#. They’re about reducing complexity as automation grows. Learn when classes add real value, how they differ from PSCustomObject, and why long-lived automation projects often benefit from a more structured approach.
