Is there possibility to test application before posting it to Google Apps marketplace for approving?
As I know, basic requirements is to support Single SignOn, but if I currently haven't Google app account, can I test my implementation of Single SignOn integration in other way? Is there some google test account, or test SSO portal?
Thanks.
No, but why don't you create a Google Apps account. The basic version is free for upto 10 accounts. All you need is a domain name.
