Mock Provider

"AIOS Mock" ships in AI Open SDK (core). It is an in-memory provider for text and image generation: no HTTP and no API keys.

Core and provider logic that you cover in CI should pass with Mock. Live API keys stay out of the pipeline.

Why it matters

AI calls are side effects. With Mock you assert on prompts, structured output, and tool loops deterministically:

• Tests run without secrets or network
• Failures stay reproducible
• Provider outages do not block CI

Setup

1. Depend on AI Open SDK (core).
2. Queue the next response (or error / tool call) on the factory.
3. Call "AIOS Client" with Mock.Model(...) or Mock.ImageModel(...).

Mock: Codeunit "AIOS Mock";
Client: Codeunit "AIOS Client";
Result: Codeunit "AIOS Generate Result";
begin
    Mock.SetNextResponse('Hello from mock');
    Result := Client.GenerateText(Mock.Model('mock-model'), 'Hello');
end;

The queued response comes back verbatim, which is what makes assertions stable:

Hello from mock

So the test asserts on a known value rather than on whatever a live model happened to say:

Assert.AreEqual('Hello from mock', Result.Output(), 'Unexpected output');

Image: Mock.SetNextImageBase64(...) then Client.GenerateImage(Mock.ImageModel(...), ...).
