Can anyone advice on how should I go about testing my APIs using jest?

Are you already familiar with Jest?

I have used it before a couple of times with sst stacks so yep, I am.

I ask because it's no different to testing anything else. Are you aiming to do unit or integration testing?

unit tests primarily.

Then it's all about mocking external dependencies

okay, but where should I be creating my tests, sst had a tests directory, should I be writing my tests in them?

I'd say that's for testing your infrastructure is deployed properly, it sounds like you want to test the code that will be run by that infrastructure. I therefore have a separate test folder inside my src folder for our tests

Yes, I want to test my code, okay, that makes sense. Where do you trigger the tests via CI?

I have an npm script that is run before deployment

so basically it’s something like

deploy: yarn test && yarn sst deploy

, is that the case?

Yes, or call it via a separate hook predeploy. E.g. In seed there are a couple of hooks you can use predeploy to run scripts

okay, thank you, as always, you were quick. I really appreciate the guidance. 🙏

No worries 😊
