Have someone unit testing examples using SST + GraphQL + AppSyncApi ?

Hey @Daniela Vaz, r u looking to unit test ur CDK code?

Ah I see… so you mean unit tests for your Lambda code

Yes

I’m not familiar with unit testing GraphQL, but for Lambda functions in general, I try to put all the business logic in side effect free functions that aren’t making AWS calls, and just unit test those functions.

Can you share some example with lambda functions ? It might help

We would need to put this together as an example but are you familiar with using Jest? https://jestjs.io You can add those tests in the

test/

dir and run

npx sst test

.

Hi Daniela. Are you familiar with unit testing in general? It’s no different with lambda. We use Jest and apply unit tests to each layer of the app, mocking any external calls made in the unit under test. This is an example of testing the lambda handler entry point
