Oauth into test/partial Salesforce environment

[camrail]

Hi there

Thanks for the library!

How is the Oauth login domain set? I have this running however it seems to be just working for our production instance and I'm not sure how to set it to the test or partial environment.

In the returned Oauth object the instance_url is login.salesforce.com when I am wanting it to be for one of the test environments like test.salesforce.com

Is there any way to switch this? Thanks.
