We have an application which track the animal data in various locations called stations. Even without internet they user can save the data to local machine. Once those data save in the local pc they need to transfer (sync) these data to main office (local PC connect to local offices and get the data) database and save there. When local office user again want to get save the data of local office he or she need to sync down data from main office. In this sync up and down conflicts can happen. We have tool developed to handle the sync and sync down , also the conflict resolution
We need to test this scenarios for various combinations. What are the possible test combinations ?
Appreciate your help.
