Problem:

• given:
  • I have an engine with several users that have access to Optimize
  • Optimize has successfully synced the users and imported the engine data
  • I create a collection in Optimize and add several user roles
• when:
  • Optimize starts another identity sync
  • the request to the engine for fetching the application authorizations returns a response with a status other than 200 OK, e.g. 500 server error
• then:
  • all the roles of the collections are being removed from the collections
• expected:
  • there are to options that need to be discussed:
    • either Optimize does a retry with backoff until it fetches all the application authorizations successfully
    • it stops the sync and does another retry when the identity sync is triggered again

Hint:

• it might make sense to have a look all the engine failing tests if those are considering both request failures, wrong status code and connection interruptions
• we might want to create a utility class that allows to perform a fetch with retry which we've already implemented in other places, e.g. the import
