yarn add cypress-parallel
In your package.json add a new script:

"cy:parallel" : "cypress-parallel -s cy:run -t 2 -d
...
}
Sample:
``
-a '\"--config baseUrl=http://localhost:3000\"'
``
npm run cy:parallel
or
Run with npx (no package installation needed)
``
npx cy:parallel -s cy:run -t 2 -d

"cy:parallel" : "cypress-parallel -s cy:run -t 4 -m false"
...
}
NB: If your cypress-multi-reporters module is not found on the same level as your Cypress suite (e.g. in a mono-repo) then you can specify the module directory for Cypress to search within.
`typescript``
"scripts" :{
...
"cy:parallel" : "cypress-parallel -s cy:run -t 4 -n .../../../node_modules/cypress-multi-reporters"
