Go for C# developers: Where to define interfaces

When writing Go code the general guideline is not to create interfaces unless it is really needed. A good example would be an interface with only one concrete implementation. Now for the mind boggling part; in C# we would probably create that interface if the type needs to be faked in some test while in Go you wouldn't. Or actually you would. But in a different place...


Another example on ways to to make your code testable

Before you go crazy on me screaming that making code testable for the sake of testability is bad I'd like to agree. However testable code have other nice properties like loose coupling for example - something you likely want.
