Discussion: is interface just for mocking a good idea? about mockery HOT 1 CLOSED

Hi, thanks for your discussion. I looked over the details of your project and it is indeed very clever. You do not see many projects interacting with Go's IR, so this is a fairly novel (to me) method of what is ultimately a style of dependency injection.

Questions I have:

 Instead, it relies on the IR representation employed by the go compiler.

What guarantees does Go provide on the compatibility of the IR across language versions? Is this essentially identical to the backwards-compatability promise?

Do you have any writing on the specifics of how you do the IR Rewriting? I'm personally interested to hear more.

At the moment, I am not convinced that such a style of DI is somehow superior in theory to interfaces, as it has become a community-wide standard, and as such I fear that you will meet major headwinds against modifying that standard. However, your idea itself is quite interesting and I welcome the discussion.

from mockery.
