Modules

bfx-api-mock-srv

This module hosts mock servers for the WSv2 and RESTv2 Bitfinex APIs, and is intended for testing the Bitfinex API libraries.

Classes

MockRESTv2Server ⇐ MockServer

REST v2 API server mock

Exposes the same routes as the real API, and maps them to a response table. Multiple potential responses can be defined for endpoints with arguments, with the best match sent to clients on request.

i.e. If the following responses are configured:

  • orders.tBTCUSD: [42]
  • orders: [41]

A GET on /v2/auth/r/orders/tBTCUSD/hist would return [42], but a query for a different symbol (tETHUSD) would return [41].

MockServer ⇐ events.EventEmitter

Mock server base class, listens for commands to get/set responses

MockWSv2Server ⇐ MockServer

Acts as a mock for v2 of the Bitfinex websocket API. Responses to available commands are loaded from data/ws2.json and can be modified at runtime. The command API allows for arbitrary packets to be injected into the ws stream.

Responses are of the form [{ packets: [...] }], where mulitple packets are sent in order. A packet can be a string referencing another response by key.
