Mockery is a project that creates mock implementations of Golang interfaces. It inspects source code and generates implementations of the interface that aid in testing.
In addition to providing a number of different styles of mocks, mockery also allows users to provide their own template files that will then be rendered using a set of template data, methods, and functions that provide comprehensive typing information about the Go interface in question.
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.
