I am developing a Java library for communication via HTTP, and I want to test its reliability and performance in case of network problems such as packet loss, high latency, low bandwidth, and congestion. I'm using Apache's httpclient library for doing connections from client side, and Java's own com.sun.net.httpserver.HttpServer for starting up HTTP servers.
Are there libraries available that do that kind of thing, or should I roll my own? I guess I could try to plug my own org.apache.http.conn.scheme.SchemeSocketFactory into the client side, and simulate several of the problems mentioned above with that, but I'd prefer to use something that works already :-)
This is similar to question Creating TCP network errors for unit testing, but I'm looking for solutions involving Java on Linux. I've looked at click, which was suggested for that question, but I'm not sure it can provide what I'm looking for.
