Function TestOnCloseHooks_NilReceiver

internal_test.go:932–937

TestOnCloseHooks_NilReceiver ensures run() on a nil registry is a safe no-op. baseClient embedded in Conn/Tx does initialize the registry, but defensive nil-safety lets future constructors add the field without breaking Close().

(t *testing.T)

// defensive nil-safety lets future constructors add the field without
// breaking Close().
func TestOnCloseHooks_NilReceiver(t *testing.T) {
	var h *onCloseHooks
	if err := h.run(); err != nil {
		t.Fatalf("run() on nil = %v, want nil", err)
	}
}

// TestOnCloseHooks_ConcurrentRegisterSameID hammers the registry with many
// goroutines re-registering under the same id. The registry must remain
