In Jest, `nock.restore()` prevents subsequent mocks from working

What is the expected behavior? Individual tests pass, running them as part of a describe block should also pass

What is the actual behavior? The first time a test makes a request its fine, but all of the subsequent requests are triggering errors:

Error: connect ECONNREFUSED 127.0.0.1:80

    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1054:14)

How to reproduce the issue Running any of these tests individually works great, running the describe block the first one works, the 2nd and 3rd throw the error

import axios from 'axios'
import httpAdapter from 'axios/lib/adapters/http'
import nock from 'nock'

const host = 'http://localhost';
axios.defaults.baseURL = host;
axios.defaults.adapter = httpAdapter;

afterEach(() => {
    nock.restore();
});

describe('hmm', () => {
    test('1', async () => {
        nock(host).get('/test1').reply(200, 'hello world');
        const rsp = await axios.get('/test1');
        expect(rsp.data).toBe('hello world');
    });

    test('2', async () => {
        nock(host).get('/test2').reply(200, 'hello world');
        const rsp = await axios.get('/test2');
        expect(rsp.data).toBe('hello world');
    });

    test('3', async () => {
        nock(host).get('/test3').reply(200, 'hello world');
        const rsp = await axios.get('/test3');
        expect(rsp.data).toBe('hello world');
    });
});

This currently works for me:

beforeEach(() => {
  if (!nock.isActive()) {
    nock.activate();
  }
});

afterEach(() => {
  nock.restore();
});

You’ve managed to expertly answer my weirdly worded question, so well done. That’s all making sense now. I’ll play around with it a bit more and see what works out well and submit a PR for that readme portion.

Thanks again
