NodeJS: understanding variable scope in modules

Vote count:

Using NodeJS v0.12.1, in the following, I am trying to read an external file into a config object, and execute some tests using the values provided by that object.

I thought that config would be in scope for the before function, but I am getting the error ReferenceError: config is not defined for the first line in the before function. Why can't config be accessed within before?

module.exports = {
  config                  : require('../../testconfig.json'),
  before                  : function (browser) {
    pass = config.pass;
    siteroot = config.local.address + config.local.subdir;
  },
  after                   : function (browser) {
    //we'll come up with something later....
  },
  'Testing the Login page': function (browser) {
    var greeting = 'Welcome, ' + user + '!';
    browser
        .url(siteroot)
        .waitForElementVisible('body', 1000)
        .setValue('input[id=UserNameEdit]', user)
        .setValue('input[id=PasswordEdit]', pass)
        .click('#LoginBtn')
        .pause(1000)
        .assert.containsText('#usergreeting', greeting)
  }
};
