[Question] ExpressJS + Typescript + Jest: Not able to record tests.

[theomelo]

Description

I clearly don't know how to configure test recording. 🙈

The problem

I'm not able to record my tests.

What I tried to do

1. Set up a simple app using ExpressJS + Typescript + Jest.

   • GH Repo
   • Codesandbox [ Select DevTools → Tasks → test:record ]

• When running the tests, they pass without error but don't create the record anywhere.

2. Running your Typescript Node example locally.

• Without changing anything, it fails. It uses setup-polly-jest to configure Polly.js, so I tried replicating the example without success.

  • GH Repo
  • Codesandbox [ Select DevTools → Tasks → test:record ]

• The error bellow happens when running my app (which you should also see in the sandbox)

$ ./node_modules/.bin/jest --runInBand
 FAIL  src/__tests__/server.test.ts
  ● Test suite failed to run

    PollyError: [Polly] Adapter matching the name `node-http` was not registered.

The rest of this issue doesn't consider setup-polly-jest since it's unrelated to my problem with Polly.js

export default polly;

[codemariner]

this is happening to me as well

[tabrez96]

Try directly passing adapters like this:

const polly = new Polly(
  'testing',
  {
    adapters: ['@pollyjs/adapter-node-http'],
    mode: 'replay',
    persister: '@pollyjs/persister-fs',
    persisterOptions: {
      fs: {
        recordingsDir: path.resolve(__dirname, '../__recordings__')
      }
    },
    recordIfMissing: true
  }
);

This is happening to me as well. I can't seem to record on code sandbox using fs and local-storage isn't persisting in my headers @offirgolan do you have any guidance? My polly config is super simple and it doesn't seem to be working?

import { Polly } from "@pollyjs/core";
import LocalStoragePersister from "@pollyjs/persister-local-storage";
import NodeHttpAdapter from "@pollyjs/adapter-node-http";
import FSPersister from "@pollyjs/persister-fs";
import FetchAdapter from "@pollyjs/adapter-fetch";

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

const config = {
  adapters: ["fetch"],
  persister: "fs",
  logLevel: "info",
  recordFailedRequests: true,
  recordIfMissing: true,
  recordFailedRequests: true,
  mode: "replay",
  persisterOptions: {
    fs: "./recording",
  },
};

export function pollyConfig(name) {
  const polly = new Polly(name, config);
  polly.server
    .any()
    .on("response", (req) =>
      console.log(JSON.stringify({ result: req }, null, 2)),
    );
  return polly;
}

@theomelo have you had any luck?

[theomelo]

@Josiassejod1, unfortunately, no. It's worth noting that I haven't been working with that stack for a while. Since there are other people with this issue, I will keep it open for now.
