My GopherCon UK 2025 talk Climbing the Testing Pyramid: From Real Service to Interface Mocks in Go can be watched on youtube.

This is the first time I am speaking at GopherCon and also in front of a large audience of nearly 150 people.

This talk explores the various strategies for unit testing Go applications that interact with cloud services like S3. Testing against real cloud services is considered the gold standard, but it’s often impractical due to access restrictions, cloud costs and the difficulty of reliably simulating failure scenarios such as network partitions. The talk focuses on the various techniques and tools that can be used to test code that interact with cloud services.

The slides and the code used in the talk are available on github.
