How to record only external requests?

I’m trying to use pollyjs to test express js endpoint. It works fine until record is persisted to file. After that it just skips actual app code, so that test becomes always green. I assume this is because localhost(127.0.0.1) request/response is being intercepted by polly. Is it possible to record only external requests to prevent this?

app.js:

router.get('/widgets', async (req, res) => {
  //some external remote calls
}

polly_config.js:

module.exports = {
  adapters: ['node-http'],
  persister: 'fs',
  persisterOptions: {
    fs: {
      recordingsDir: `${__dirname}/http_recordings`,
    },
  },
  recordFailedRequests: true,
  recordIfMissing: false,
  matchRequestsBy: {
    headers: false,
  },
};

app.spec.js:

const chai = require('chai');
const { expect } = chai;
const chaiHttp = require('chai-http');
chai.use(chaiHttp);

const { Polly } = require('@pollyjs/core');
const NodeHttpAdapter = require('@pollyjs/adapter-node-http');
const FSPersister = require('@pollyjs/persister-fs');
const pollyConfig = require('./polly_config');

Polly.register(NodeHttpAdapter);
Polly.register(FSPersister);

describe('app', () => {
  const testPort = 3001;
  before(() => {
    app.listen(testPort);
  });

  describe('GET widgets', () => {
    it('returns widgets requested', async () => {
      const polly = new Polly('get_widgets', pollyConfig);

      const response = await chai.request(`http://127.0.0.1:${testPort}`)                                           
                                 .get(`/widgets`)
      expect(response).to.have.status(200);

      await polly.stop();
    });
  });

If you’re using mocha, I highly recommend using the setupMocha test helper.

import { setupMocha as setupPolly } from '@pollyjs/core';

describe('app', function() {
  const testPort = 3001;

  before(() => {
    app.listen(testPort);
  });

  setupPolly({ ...pollyConfig });

  beforeEach(function() {
    const { server } = this.polly;

    server.any(`http://127.0.0.1:${testPort}/*`).passthrough();
  });

  describe('GET widgets', () => {
    it('returns widgets requested', async () => {
      const response = await chai.request(`http://127.0.0.1:${testPort}`).get(`/widgets`)
      expect(response).to.have.status(200);
    });
  });
});

Correct. I’m gonna go ahead and close this issue. Feel free to reopen or create a new one if you have any more questions.
