Is there a way to create unit tests for Salesforce to Salesforce without setting SeeAllData=true? 

I can't seem to create test objects for PartnerNetworkRecordConnection and PartnerNetworkConnection. Is there a way to create unit test cases without using live test data for Salesforce to Salesforce? 

Is there a way to have an auto-number that is shared between two Salesforce to Salesforce organizations? Essentially, I want an auto-number that is synchronized between two organizations such that it can be used to identify new objects getting created.
