Test Doubles

Crafting resilient code is one of the most important things we do as software developers, but it’s much easier said than done! Building with confidence requires an appropriate test harness and automated safeguards to ensure your software is robust. In most real world scenarios, we don’t have the luxury of working with a green field project, so it can be difficult to apply best practices whilst maintaining legacy code. How then can we refactor, and effectively utilise test fakes appropriately?...

In software development, mocking is a popular technique used to simulate dependencies and test behaviour without relying on external systems. However, as with any technique, there are pros and cons to using mocks. In this talk, I’ll discuss why using mocks may not be the best approach and why we should instead use fakes or in-memory implementations of well-defined interfaces. We will explore the drawbacks of mocks, including how they can lead to brittle tests, slow down development, and make it difficult to refactor code....
