Not actively maintained, may not work with latest node.js runtimes. If you are interested in maintaining toxy, please open an issue.
Hackable HTTP proxy to simulate server failure scenarios, systems resiliency testing and unexpected network conditions, built for node.js.
It was mainly designed for failure resistance testing, when toxy becomes particularly useful in order to cover fault tolerance and resiliency capabilities of a system, especially in disruption-tolerant networks and service-oriented architectures, where toxy may act as MitM proxy among services in order to inject failure.
toxy allows you to plug in poisons, optionally filtered by rules, which essentially can intercept and alter the HTTP flow as you need, performing multiple evil actions in the middle of that process, such as limiting the bandwidth, delaying network packets, injecting network jitter latency or replying with a custom error or status code. It primarily operates at L7, although it can simulate L3 network conditions.
toxy can be fluently used programmatically or via HTTP API. It was built on top of rocky, a full-featured middleware-oriented HTTP proxy, and it's also pluggable in connect/express as standard middleware.
Requires node.js +4.
