Set the IP address of the outgoing test request

[apratheek]

Hi, is there any way to set the IP address of the mock request? I have a use case where I need to know the IP address of the incoming request. The library sets the IP address to an empty string. I need to set it to a particular value (could default to 127.0.0.1). Any help would be much appreciated.

Thanks

I've been doing this by setting a fake server address directly after creating the engine:

e := NewEngine()
e.Server.Addr = FakeServerAddress

Rather than using c.Request().Host directly this must be matched on the server side with something like:

// get the IP address of the running server
func GetServerAddress(c echo.Context) string {
	serverAddress := c.Request().Host
	if serverAddress == "" {
		// normally we use the address given in the HTTP request
		// this is not set by gofight in unit tests so we use the listener address instead
		if c.Echo().Server != nil {
			serverAddress = c.Echo().Server.Addr
		} else if c.Echo().Listener != nil {
			serverAddress = c.Echo().Listener.Addr().String()
		}
	}
	return serverAddress
}

as this could be a different IP & port. For example, if your server is running inside a docker container.
