Integration fakes prevent accidental real API calls during Laravel testing by using in-memory replacements bound via contracts and facades. This ensures tests remain deterministic and isolated from real-world interactions.

A contract-based fake in Laravel is an in-memory replacement implementing a shared interface for an external service. It uses container bindings and facades to intercept calls, enabling deterministic testing without real-world interactions.

You assert application calls using built-in assertion helpers provided by the integration fake. These helpers record incoming calls and verify that specific integrations were executed with the exact expected parameters during testing.

Yes, Laravel integration fakes support seeded responses and exceptions. This provides predictable outputs for tests, ensuring your application handles both successful interactions and expected failures deterministically.

Yes, this approach works for testing payment gateways and courier integrations in PHP. You design in-memory fakes based on service contracts, preventing actual API calls while providing clear assertion capabilities.

The best way to isolate external dependencies in Laravel feature tests is using integration fakes. By binding in-memory replacements to contracts via the container, you prevent real-world interactions and gain call recording for reliable assertions.
