Best practices for mocking third-party clients e.g. AWS SDK in nitro
i am writing integration tests for my nitro framework API (nitro.build). I'm currently using nitro-test-utils to spin up a global nitro server instance to run my $fetchRaw requests against. The problem is I need to mock some calls to AWS services inside some internal functions of my endpoints. I can't seem to get vi.mock or vi.spyOn to work as they don't seem to target the function or AWS clients bundled in my running server instance. I only need to mock the functions in some tests, and i need to be able to set the desired response payload from within my test.

Hi @Danny. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

I'm sorry, but the knowledge sources do not contain explicit information or best practices specifically for mocking third-party clients like the AWS SDK in Nitro integration tests. The available documentation and examples focus on mocking Nuxt auto-imports, components, and endpoints using helpers like

mockNuxtImport, mockComponent, and registerEndpoint for unit testing within the Nuxt ecosystem, but do not address mocking external libraries or SDKs within a running Nitro server instance during integration tests.
If your AWS SDK usage is encapsulated in composables or utility functions, you might be able to use mockNuxtImport to mock those, as shown for other auto-imported composables. However, for direct third-party dependencies bundled in the server, the provided sources do not describe a supported or recommended approach for mocking them in the context of a running Nitro server instance or integration tests. You may need to consult Nitro or Vitest documentation directly or seek community advice for this specific use case.
If you have control over the abstraction layer (e.g., wrapping AWS SDK calls in your own composables or modules), you could mock those abstractions using mockNuxtImport as described in the docs, but this is not the same as mocking the SDK itself within the Nitro runtime environment Nuxt Testing: mockNuxtImport.
