How deeply does Machine Learning System Design cover integration test?

Explains comprehensive testing and backward compatibility but does not detail individual test cases or implementation techniques.

Integration test

As explained in Machine Learning System Design

A test that evaluates interactions among multiple software components or between a component and an external system.

An integration test checks whether multiple components work harmoniously together, especially when releasing infrastructure such as a model wrapper that depends on software, services, or system requirements. section 13.5.1

Use integration testing to:

Verify that wrapper changes do not disrupt existing services. section 13.5.1
Check interactions with software updates, third-party services, and system requirements. section 13.5.1
Validate that preprocessing, feature engineering, and related pipelines remain consistent during model rollout. section 13.5.1

Supermegaretail wrapper release

Before releasing a demand-prediction wrapper, run comprehensive integration tests across its services and dependencies. Confirm backward compatibility so existing services continue operating, then monitor system health, uptime, response times, and error rates after deployment. section 13.5.1

GET /predictions?query=<query_string>&parameters=<parameters>&version=
<version>
&limit=<limit>&request_id=<request_id>&sku=<sku>&entity_id=<entity_id>
&group=<group_type>

Use the prediction endpoint as the integration boundary, checking that requests carrying query, parameters, version, and entity identifiers reach the correct services. section 13.5.1

mockinguses · Mocking is a testing technique that replaces a real dependency with a controlled substitute to simulate behavior or inspect interactions.
mutable shared stateuses · Mutable shared state is data or computational state that multiple components or execution contexts can access and whose value can change over time.
end-to-end testingincludes · End-to-end testing evaluates a complete system workflow across integrated components, from an external or user-relevant input to an observable outcome.
out-of-process dependencyuses · An out-of-process dependency is a dependency that runs outside the application's execution process and provides access to data or services external to in-memory execution.
real dependencyuses · A real dependency is an actual implementation or external service whose behavior or state is used during a test instead of a test double.
