Slow server

Sometimes one has to test again a service which may behave slowly.

How to

Slow-server enables this type of testing. You can do a request to the service with the query parameter response_time. The server will stall the request untill that timeout (in milliseconds) is matched. At that point it will return a status as described in the query parameter return_status (which will default to 200 OK if omitted).

Example

curl -vvv 'http://localhost:8080?response_time=1000&return_status=201' -vvv

yields the following response

* Rebuilt URL to: http://localhost:8080/?response_time=1000&return_status=201
*   Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 8080 (#0)
> GET /?response_time=1000&return_status=201 HTTP/1.1
> Host: localhost:8080
> User-Agent: curl/7.51.0
> Accept: */*

Service responded with status code 201, delayed by 1000 milliseconds. Use the query parameter `response_time` to give the timeout in milliseconds, or specify the returned status code using `return_status`.
