The context library recommends never using a nil Context, and context.Background() provides an empty Context appropriate for use in unit tests.

OAuth2 for Go
oauth2 package contains a client implementation for OAuth 2.0 spec.
Installation
go get golang.org/x/oauth2
See godoc for further documentation and examples.
App Engine
In change 96e89be (March 2015) we removed the oauth2.Context2 type in favor
of the context.Context type from
the golang.org/x/net/context package
This means its no longer possible to use the "Classic App Engine"
appengine.Context type with the oauth2 package. (You're using
Classic App Engine if you import the package "appengine".)
To work around this, you may use the new "google.golang.org/appengine"
package. This package has almost the same API as the "appengine" package,
but it can be fetched with go get and used on "Managed VMs" and well as
Classic App Engine.
See the new appengine package's readme
for information on updating your app.
If you don't want to update your entire app to use the new App Engine packages,
you may use both sets of packages in parallel, using only the new packages
with the oauth2 package.

"golang.org/x/net/context"

var c appengine.Context = appengine.NewContext(r)
c.Infof("Logging a message with the old package")
var ctx context.Context = newappengine.NewContext(r)

Transport: &oauth2.Transport{
