This is a quick tutorial on how to test code using the GoMock mocking library and the standard library testing package testing.
GoMock is a mock framework for Go. It enjoys a somewhat official status as part of the github.com/golang organization, integrates well with the built-in testing package, and provides a flexible expectation API.
This is not an exhaustive list of all interfaces in Go's standard library.
I only list those I think are important.
Interfaces defined in frequently used packages (like io, fmt) are included.
Interfaces that have significant importance are also included.
All of the following information is based on go version go1.8.3 darwin/amd64.
