You'll want to look into gomock and mockgen. To get started mocking,
you'll need an interface, so maybe writing a receiver function
encapsulating os.Hostname(), then consuming that with an interface.
type OsClient struct {}
func (o *OsClient) GetOSHostname() (string, error) { return os.Hostname() }
type HostnameGetter interface { GetOSHostname() (string, error) }
Gomock repo w/ documentation: https://github.com/golang/mock
Nice intros to gomock:
