In cypress.json there is one env variable:

  "env": {
    "AUTH_TOKEN": "token_1"
  },

I have multiple users in db and would like to test them separately without editing cypress.json. Cypress documentation provides two possible ways how to override env variables form command line:

cypress run --env AUTH_TOKEN="token_2"

and

AUTH_TOKEN="token_2" cypress run

When I run cypress interface with

npm run cy:open --env AUTH_TOKEN="token_2"

or

AUTH_TOKEN="token_2" npm run cy:open

token_1 does not get overriden with token_2. Why is cypress ignoring options provided in command line?

npm run requires a -- to pass parameters to script cy:open in package.json,

npm run cy:open -- --env AUTH_TOKEN="token_2"

or use yarn

yarn cy:open --env AUTH_TOKEN="token_2"

or bypass the script

yarn cypress open --env AUTH_TOKEN="token_2"

or

npx cypress open --env AUTH_TOKEN="token_2"
