- This repo is structured similar to how other "Monorepos" work.
- Each
example projecthas its own Cypress configuration, tests, backend and frontend assets. - Each of these
example projectsshare a single "root" Cypress that is installed in the rootnode_modulesfolder. - This structure looks different from normal projects, but its the easiest way to manage multiple projects without installing Cypress independently for each one.
## install all dependencies from the root directory
npm installcd ./examples/testing-dom__drag-drop
# start local server
npm start &
# and open Cypress GUI
npm run cypress:openSame 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 -- --recordYou can find the recording at the Cypress Dashboard linked below
