Colossus S3 testing

[ignazio-bovo]

Unit testing

The interface itself doesn't present precondition that should be tested in isolation. I will skip this for now

Integration testing

The IConnectionHandler will be mocked, for these tests. The objective is to test the interaction between Service and IConnectionHandler, with Service being

• Sync/StorageProviderSyncTask
• Sync/DeleteObject
• getFile
• AcceptObject

E2E (local)

• content scenario run with STORAGE_PROVIDER_ENABLED=true and wrong AWS credential should panic and shut down Colossus immediately (to avoid lost objects errors)
• content scenario run with localstack and STORAGE_PROVIDER_ENABLED=true and correct setting should provide a successful scenario run
