nock-proxy

Mock network requests with nock through a proxy - perfect for real-life environments like end-to-end tests on a real browser.

Install

npm install nock-proxy

How does it work

Nock overrides the http.request function of the node process it is running in. This means that we can spawn a simple pass-through proxy server which will reply with a mock if said mock is being expected via nock.

Example

const nock = require("nock")
const nockProxy = require("nock-proxy")

// Launch the proxy server on your desired port on localhost.
// Don't forget to setup your browser to use this proxy.
nockProxy(8081)

// Setup your mocks via nock, as usual. Use the option allowUnmocked
// to avoid errors from unexpected requests.
nock("http://www.example.de", { allowUnmocked: true })
    .get(/.*/)
    .reply(219, {
        hello: "world",
    })

One test for end-to-end and integration

nock-proxy turns end-to-end tests into integration tests: Simply set up the browser to pass through nock-proxy for having mocks like in an integration test environment. Don't pass through the proxy for using real-world network requests.
