GoMock is a mocking framework for the Go programming language.
Go Reference
gomock is a mocking framework for the Go programming language. It integrates well with Go's built-in testing package, but can be used in other contexts too.
This project originates from Google's golang/mock repo. Unfortunately, Google no longer maintains this project, and given the heavy usage of gomock project within Uber, we've decided to fork and maintain this going forward at Uber.
Thou Shalt Write Tests.
A toolkit with common assertions and mocks that plays nicely with the standard library.
