Refactoring and Test Fakes: Crafting Resilient Code with Confidence

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 this talk, I'll discuss the best approaches for using test fakes, mocks, stubs, and what are the pros and cons for each. How we can avoid writing brittle tests, slowing down development, and build scalable apps that can stand the test of time.

What a Long Strange Trip it's Been: A Year In Android

The Android community is a fast evolving society of excellent people who passionately involve themselves in their ecosystem. This means the progress of developments can be fast, blazingly fast!

Inspired by other content creators and newsletters that keep us informed about the most recent events, I decided to document news, events, and releases every week for a year. Starting from the end of Droidcon Berlin, the world’s best Android developer conference.

Accompany me in this journey to look over all the events of this last year, from the end of Droidcon Berlin 2022 up until right now!
