RpcCallSpy class

An IRpcInterceptor that records every RPC call for later inspection.

Attach to RpcTestApp or RpcApp to capture calls during tests, then assert on entries, callsTo, callCount, etc.

final spy = RpcCallSpy();
final app = await RpcTestApp.start(
  modules: [EchoModule()],
  interceptors: [spy],
);

final client = EchoCallerContract(app.caller);
await client.ping(PingRequest('hello'));
await client.ping(PingRequest('world'));

expect(spy.callCount, 2);
expect(spy.callsTo('EchoService', 'ping'), hasLength(2));
expect(spy.entries.first.success, isTrue);
expect(spy.wasCalled('EchoService', 'ping'), isTrue);
