E-commerce Test Automation with Cypress

This project contains end-to-end tests for a mock e-commerce application using Cypress with TypeScript and the Page Object Model pattern.

Overview

The tests automate two main flows:
1. Successful order flow - a user who can complete a purchase successfully
2. Failed order flow - a user whose payments are always declined

Setup

1. Clone the repository
2. Install dependencies:

   npm install

   

3. Set up environment variables:
- Create a cypress.env.json file (already included but should not be committed to version control in a real project)
- Or use a .env file with the necessary credentials

Running the Tests

Run all tests:

npm test

Run tests in headless mode:

npm run test:headless

Run specific test flow:

npm run test:success  # Successful order flow

npm run test:failure  # Failed order flow

Open Cypress GUI:

npm run cypress:open

Environment Variables

The following environment variables are used:

- CYPRESS_USERNAME: Username for successful login
- CYPRESS_PASSWORD: Password for both users
- CYPRESS_FAILURE_USERNAME: Username for the user with failed payments

These can be set in:
1. cypress.env.json file (for local development)
2. .env file
3. CI/CD pipeline environment variables

Test Application

The tests are designed for the mock e-commerce application located at:
https://v0-imagine-deals.vercel.app

Notes

- This is a demo project for testing purposes only
- The application simulates payment scenarios:
- Any total ending in .99 will simulate a declined payment
- Any total ending in .88 will simulate a network error
