        name: 'foo',
      },
    },
  };
};
const mockedNetworkFetch = createMockedNetworkFetch(createResponse, { timeout: 100 }); // you can simulate network latency
const client = new ApolloClient({
  link: createHttpLink({ uri: 'http://localhost:3000', fetch: mockedNetworkFetch }),
  cache: new InMemoryCache(),
