Using nock with sinon fake timers

This is more of a question rather than an issue report.

When I use Sinon to fake the current date and time like so: Sinon.useFakeTimers(new Date("2016-01-01T00:11:22+10:00").getTime());

And then I call Nock to intercept, it never registers the URL (confirmed by turning debugging on).

However if I don’t use Sinon fake timers and I use something like mockdate js, it works.

Just curious as to what is happening here.

Thanks.

Having the same problem as described above. I have a method that does long polling (and uses setTimeout to trigger itself in time intervals). When I use sinon fake timers nock requests are not fired at all.

My test code looks like this:

import "../utils"
import { expect } from "chai"
import * as sinon from "sinon"
import nock = require("nock")
import { Resource } from "../../src/resources/Resource"
import { Scope } from "nock"
import { POLLING_INTERVAL } from "../../src/constants"

describe("Charges", () => {
    let resource: Resource
    let scope: Scope
    const testEndpoint = "http://localhost:80"
    let sandbox: Sinon.SinonSandbox

    beforeEach(() => {
        resource = new Resource()
        scope = nock(testEndpoint)
        sandbox = sinon.sandbox.create({
            properties: ["spy", "clock"],
            useFakeTimers: true
        })
    })

    afterEach(() => {
        nock.cleanAll()
        sandbox.restore()
    })

    context("route GET /poll", () => {
        it("should perform long polling until condition is met", () => {
            let repeats = 3
            const spy = sandbox.spy(global, "fetch")
            const scopeScope = scope
                .get(/\/poll$/i)
                .thrice()
                .reply(200, () => {
                    sandbox.clock.tick(POLLING_INTERVAL)
                    return { status : repeats-- === 0 ? "success" : "pending" }
                }, { "Content-Type" : "application/json" })

            return resource.poll("1", "1").should.eventually.eql({ status : "success" })
                .then(() => expect(spy).to.have.been.calledThrice)
        })
    })

})
