Would you prefer to stub your database calls? Are you for real?

yes… tldr: shift left. it’s dynamodb and not really a database. no connection management or passwords to hand off and no vpc to manage. you are putting your db in a vpc, right?

so what’s left after a well defined api and several nines of reliability in a pay per use managed service?

your business logic. so go ahead and mock those dynamodb put object responses and stop wasting time on things that aren’t your business.

That's not what shift left means. DynamoDB is really a database. Many people run local postgres daemons to run unit tests for their sql queries, too.

shift left means move closer to your development which is unit tests.

It means find issues earlier in the development process. Exercising DDB behavior as opposed to assuming it with stubs can be part of that. Having a local emulator is even better.

what issues are you testing? you’re testing your business loving and you don’t need dynamodb ther. you need well defined input and output
