nock-record v0.3.9

Small wrapper around Nock Back, with improved ergonomics.

:heavy_check_mark: Testing framework agnostic\ :heavy_check_mark: Types included\ :heavy_check_mark: Works with promises (so enables async/await)

Workflow

If you're familiar with Jest Snapshots, the following workflow should feel familiar.

1. Record actual HTTP requests on first-time test run
2. Request + response are written to a file
3. A nock will be created on subsequent test runs, based on the previous recording

Installation

Make sure to install nock as well, as it's defined as a peer-dependency:

# yarn
yarn add nock-record nock -D

# npm
npm install nock-record nock -D

Usage

import { setupRecorder } from "nock-record";
import { getGithubProfile } from "./githubProfile";

const record = setupRecorder();

describe("#getGithubProfile", () => {
  it("should retrieve user info", async () => {
    // Start recording, specify fixture name
    const { completeRecording, assertScopesFinished } = await record("github-edorivai");

    // Run your function under test
    const result = await getGithubProfile("edorivai");

    // Complete the recording, allow for Nock to write fixtures
    completeRecording();
    // Optional; assert that all recorded fixtures have been called
    assertScopesFinished();

    // Perform your own assertions
    expect(result).toMatchSnapshot();
  });
});
