gomocklinter

A linter that checks the usage of go mocking libraries

Note: The original golang/mock package is archived and the maintained fork is go.uber.org/mock.
This linter supports both.

Installation & usage

$ go install github.com/hendrywiranto/gomocklinter@latest
$ gomocklinter ./...

or build the binary and use go vet

$ go build -o gomocklinter main.go
$ go vet -vettool=./gomocklinter ./...

Motivation

As highlighted in https://pkg.go.dev/github.com/golang/mock/gomock#NewController

New in go1.14+, if you are passing a *testing.T into this function you no longer need to call ctrl.Finish() in your test methods.

Examples

// Bad
func TestFoo(t *testing.T) {
	mock := gomock.NewController(t)
	defer mock.Finish() // no need to call this since go1.14
}

// Good
func TestFoo(t *testing.T) {
	mock := gomock.NewController(t)	
}
