Connectum API Reference / @connectum/testing / index / mockService

Function: mockService()

mockService<S>(service, impl): MockService

Defined in: testing/src/mockResolver.ts:44

Type-safe constructor for a MockService. Pairs a service descriptor with handlers typed against it.

A handler that throws a ConnectError answers with exactly that error. Any other exception (a typo in the mock, a rejected promise, a thrown string) reaches the caller as a ConnectError with code Internal, the exception's own message and the exception itself as cause, so a broken mock shows up in the test output instead of as an anonymous "internal error".
