My plan is to store a username and password as system environment variables and reference them in an Angularjs Protractor config file. I defined the variables in /etc/environment. This is what I've tried so far:

params: {

  login: {

    user: $E2E_USER,

    pass: $E2E_PASS

  }

}

I also tried this:

params: {

  login: {

    user: process.env.E2E_USER,

    pass: process.env.E2E_PASS

  }

}

Any help would be much appreciated!
