Overview

• This repo is structured similar to how other "Monorepos" work.
• Each example project has its own Cypress configuration, tests, backend and frontend assets.
• Each of these example projects share a single "root" Cypress that is installed in the root node_modules folder.
• This structure looks different from normal projects, but its the easiest way to manage multiple projects without installing Cypress independently for each one.

Installation

## install all dependencies
npm install

Opening Cypress GUI

cd ./examples/testing-dom__drag-drop
# start local server
npm start &
# and open Cypress GUI
npm run cypress:open

Running from the CLI

Same as running Cypress GUI but with cypress run command (and any CLI arguments)

cd ./examples/testing-dom__drag-drop
# start local server
npm start &
# run Cypress tests headlessly
npm run cypress:run

### runs all example projects in specific browser
### similar to cypress run --browser <name>
npm run cypress:run -- --browser chrome

### sends test results, videos, screenshots
### to Cypress dashboard
npm run cypress:run -- --record

Development

See Development.md
