How do I use GoMock for testing in Go?

GoMock is a mocking framework for Go that helps you create mock objects for testing. First, you need to install it using go get github.com/golang/mock/gomock.

What are the steps to create a mock object?

To create a mock object, define an interface for the behavior you want to mock, then use the mockgen tool to generate the mock implementation.

Can you show me an example of generating a mock?

Sure! If you have an interface MyInterface, you can run mockgen -source=yourfile.go -destination=mock_myinterface.go -package=mypackage to generate the mock.

How do I use the generated mock in my tests?

In your test, create a new mock controller, then create an instance of your mock. You can set expectations and call methods on it just like a real object.
