// This file does not import KituraNet and is relying on the typealias of
// HTTPStatusCode. This test is a simple response test to check that referring
// to HTTPStatusCode builds and runs without error. Other existing tests
// that import KituraNet should be sufficient to show that the typealias does not
// interfere in that case.
