Getting started

To install via the nuget package console

Install-Package Toxiproxy.Net

A copy of toxiproxy compiled for windows is in the compiled folder. Linux, Darwin and Windows builds are available from the official release site

Usage

The unit tests give a good overview of how to fully use the api. Here are some examples to get started -

Start Toxiproxy

_proxyProcess = new Process()
    {
        StartInfo = new ProcessStartInfo(@".\packages\Toxiproxy.Net\compiled\Win64\toxiproxy-server-2.1.2-windows-amd64.exe")
    };
_proxyProcess.Start();

Set up a proxy

var connection = new Connection();
var client = connection.Client();

//proxy all traffic from 127.0.0.1:44399 to https://google.com
var localToGoogleProxy = new Proxy() { 
    Name = "localToGoogle", 
    Enabled = true, 
    Listen = "127.0.0.1:44399", 
    Upstream = "google.com:443" 
};

client.Add(localToGoogleProxy);

Disable a proxy

var connection = new Connection();
var client = connection.Client();
var proxy = client.FindProxy("localToGoogle");

proxy.Enabled = false;
proxy.Update();

Timeout a proxy

var connection = new Connection();
var client = connection.Client();
var proxy = client.FindProxy("localToGoogle");

var timeoutProxy = new TimeoutToxic();
timeoutProxy.Attributes.Timeout = 100;
timeoutProxy.Toxicity = 1.0;

proxy.Add(timeoutProxy);
proxy.Update();

Return a list of all proxies

var connection = new Connection();
var client = connection.Client();

client.All();

Reset all proxies to a good state automatically

// assuming the proxy is running with its default settings e.g. localhost:8474
// and there is a connection defined with the name "ms_sql"
// create a connection to toxiproxy that will call reset on disposal
// this resets the state of all the toxics and re-enables all of the proxies
    using (var connection = new Connection(true))
    {

        // find the upstream latency toxic
        var proxy = connection.Client().FindProxy("ms_sql");
        var latency = (LatencyToxic)proxy.GetToxicByName("Latency");


        // set a latency of 1 second 
        latency.Attributes.Latency = 1000;

        // save it
        proxy.Update();

        // do your test....

    }
