GoMock Documentation

The sample directory provides a non-trivial example of mocking interfaces. Use these files to understand the workflow:

• user.go: Contains the source code and interfaces intended for mocking.
• user_test.go: Demonstrates how to use mocks in actual tests, including creating mock objects and setting up expectations.
• mock_user_test.go: The actual code generated by mockgen. You can find the go:generate command used to create this file in ../gomock/matchers.go.

To see a complete demonstration of GoMock in action—including interface definition, mock generation, and expectation setting—you can run the provided sample tests using the following command:

go test github.com/golang/mock/sample

Install the mockgen tool using go install for Go 1.16+ or go get for older versions. Ensure $GOPATH/bin is in your PATH.
