I'm wondering, should this then force close all connections? What does net/http do in this case?

The use of Shutdown does not force all connections to close, but rather uses context to control the timeout after all listener have been closed.

func (s *Server) Shutdown() error { should be equivalent to s.ShutdownWithContext (context.Background())

Perhaps call the function Close instead. Remember it must try and gracefully shutdown first until context expires, then it kills all connections and shutsdown comprehensively.

ln := fasthttputil.NewInmemoryListener()
s := &Server{
Handler: func(ctx *RequestCtx) {
ctx.Success("aaa/bbb", []byte("real response"))

Can you add a time.Sleep(time.Millisecond*100) here and test that ShutdownWithContext returns correctly after the timeout? The test you have now just tests the code that is similar to what TestShutdown already tests. Thanks!
