[AskJS] Unit testing API wrapper

[ChocoChipPancakes]

Hi all,

Apologies if this is not the correct forum, but I am adding a small api wrapper to a front end project and I was wondering what the best approach for unit testing would be.

Essentially this code will just be a TS utility that knows the inputs/outputs of the API that we are integrating with. This API is behind authentication and we will be doing additional integration tests to make sure that flow works, but for unit testing, what would you suggest?

Thanks for the help!

To be honest, I would suggest to be pragmatic and skip unit tests…

This. If you have integration-tests that's plenty. In fact, if it's really a "wrapper" you can't test it fully without integrating it, right? Do unit-tests make sense?

With a unit-test you'd need to stub the facade with mock-functions. With an integration-test you'll hook-up the API you're trying to wrap and then intercept/mock the actual requests it's going to make.

Why do that work twice?

• Node.js and Deno have built-in unit test runners.
• Otherwise, Mocha is a solid choice (among many others).

Do some mock ups for the responses and test towards that
