One way is to use theCYPRESS_prefix.

To make things simpler (OS independent), use packagecross-env.

Install

npm install --save-dev cross-env

package.json

"scripts": { "cy:run": "cross-env CYPRESS_ENVI=QA cypress run", ... }

Test with a simple test:

it('检查cross-env是否已设置CYPRESS_ENVI', () => { expect(Cypress.env('ENVI')).to.eq('QA') // 通过 })

Using the following command worked for me:

Set the value of the environment variable as follows:

$env:ENVI=QA(on Windows)

And change the script command as follows:

UseENV=%ENVI%instead ofENV=${ENVI}

"cy:parallel" : "cypress-parallel -s cy:run -t 4 -d cypress/e2e/features/ -m false -a '\"--env ENV=%ENVI%\"'"
