@gmlewis I am stuck here for long time, please help me with this
I wrote the unit test but I don't know how to test it. I read how to contribute file aka contributing.md, but when I forked the repository and run go build ./... and go test ./... and it failed to find packages but when I clone go-github and run same commands then I am able to build and compile

It looks like you are missing dependencies needed by this package. You should be able to run go get -u github.com/google/go-github and it will get all the needed dependencies. Alternatively, you can run go get -u on each package that is missing, but that shouldn't be necessary.
