Nightwatch.js installs a test environment through a configuration file

Question

Noob Node Warning. How to programmatically establish which configuration object to use when starting a test?

It was quite difficult to find the final answer.

Setup:

/e2e-tests
    |-globals.js
    |-product.page.notify.stock.js
|-nightwatch.json 
|-nightwatch 

• nightwatch.json = setup
• nightwatch = #!/usr/bin/env node require('nightwatch/bin/runner.js');
• e2e-tests / globals.js Overkill and does not show implementation
• productpage.notify.stock.js

var SITE_URL = 'http://dev.local/', //this needs to be set somehow production||dev
  AJAX_URL = 'ajaxproc/getrandomoutofstock', //relative so this doesn't need to change
  select = '#mysize',
  emailError = '.error-message',
  outOfStockItem = {
    id: false,
    url: false
  };

module.exports = {
  'Get backorder stock url': function(browser) {
    browser.url(SITEURL + AJAX_URL)
      // ommitted for brevity
  },
  'Check notify stock on product page': function(client) {

    client.url(SITE_URL + outOfStockItem.url);
    // ommitted for brevity
  },

  // remaining test stuff - not needed
};

Run codeHide result

I saw this method here MateuszJeziorski , but omits the means to get the process arguments. The examples provided by the night review also do not answer this question. I think the end result of the command would look something like this:

nightwatch -somekindofparametertosetenvironment -t e2e-tests/product.page.notify.stock
