easy-network-stub

An easy class to mock a lot of network requests in any e2e framework or in rapid prototyping.

Framework specific packages 🧪

• Cypress
• Playwright
• Angular (third party & for rapid prototyping)

Motivation 💥

When running tests in e2e frameworks, sometimes you want to mock all network requests. Especially when running tests in a CI environment. This package provides an easy and type safe way to mock network requests for a whole API.

Also, when you are prototyping a new feature, you might want to mock a whole API to get a feeling for the UI. This package provides an easy way to do so.

Features 🔥

✅ Easy to setup and use

✅ Type safe url and query parameters

✅ Add your own parameter matchers

✅ Works asynchronously (Promise based)

✅ Supports failing of stubbed requests

✅ Supports EventSource & ndjson

✅ Supports WebSockets

✅ No production dependencies

✅ ESM exports

The primary use case for this package is to create a mock server for your tests so that they do not need real network requests.

Built With 🔧

• TypeScript

Usage Example 🚀

You can find usage examples in the existing framework-specific wrappers for this package: Playwright or Cypress

WebSockets

When testing a WebSocket connection, you can use the EasyWsStub class. This helper will create a WebSocket server that your client connects to. You can then send messages to the client and receive messages from the client.

import { EasyWsStub } from 'easy-network-stub/ws';

const wsStub = new EasyWsStub(1337, 'connect');
await wsStub.init();
wsStub.send('{"value": "test123"}');


wsStub.close();

Strongly typed api parameters

You can add types to parameters and they will be parsed. Out of box 'string', 'number' and 'boolean' are supported. You can add your own types and parsers though.
