Hi, there! 👋

This is a special fork of the Real World App you can use to install and set up Cypress and write tests from scratch for the purpose of learning Cypress or teaching Cypress to others. The Cypress project and some extraneous dependencies and config were removed, but the application is exactly the same. Enjoy!

---

A payment application to demonstrate real-world usage of Cypress testing methods, patterns, and workflows.

💬 Note from maintainers

This application is purely for demonstration and educational purposes. Its setup and configuration resemble typical real-world applications, but it's not a full-fledge production system. Use this app to learn, experiment, tinker, and practice application testing with Cypress.

Happy Testing

Features

🛠 Built with React, XState, Express, lowdb, Material-UI and TypeScript ⚡️ Zero database dependencies 🚀 Full-stack Express/React application with real-world features and tests 👮‍♂️ Local Authentication 🔥 Database Seeding with End-to-end Tests 💻 CI/CD + Cypress Dashboard

Getting Started

The Cypress Real-World App (RWA) is a full-stack Express/React application backed by a local JSON database (lowdb).

The app is bundled with example data (data/database.json) that contains everything you need to start using the app and run tests out-of-the-box.

🚩 Note

You can login to the app with any of the example app users. The default password for all users is s3cret. Example users can be seen by running npm run list:dev:users.

Prerequisites

The only requirement for this project is to have Node.js version 12 installed on your machine. Refer to the .node-version file for the exact version.

TypeScript will be added as a local dependency to the project, so no need to install it.

Installation

npm install

Run the app

npm run dev

Start Cypress

npm run cypress:open

Tests

Type	Location
api	cypress/tests/api
ui	cypress/tests/ui
unit	src/__tests__

Database

• The local JSON database located in data/database.json and is managed with lowdb.

• The database is reseeded each time the application is started (via npm run dev). Database seeding is done in between each Cypress End-to-End test.

• Updates via the React frontend are sent to the Express server and handled by a set of database utilities

• Generate a new database using npm run db:seed.

• An empty database seed is provided along with a script (npm run start:empty) to view the application without data.

Additional NPM Scripts

Script	Description
dev	Starts backend in watch mode and frontend
start	Starts backend and frontend
types	Validates types
db:seed	Generates fresh database seeds for json files in /data
start:empty	Starts backend, frontend and Cypress with empty database seed
tsnode	Customized ts-node command to get around react-scripts restrictions
list:dev:users	Provides id and username for users in the dev database

For a complete list of scripts see package.json

Code Coverage Report

The Cypress Real-World App uses the @cypress/code-coverage plugin to generate code coverage reports for the app frontend and backend.

To generate a code coverage report:

1. Run npm run cypress:run --env coverage=true and wait for the test run to complete.
2. Once the test run is complete, you can view the report at coverage/index.html.
