Loading of different URLs w/ PageObjects fails

[davidlinse]

I think there might be an unexpected behavior when one attempts to load different URLs with a Page-Object. Please see the following two examples.

module.exports = {
  after: function(browser) {
    browser.end();
  },

  // works as expected
  'Attempt to load multiple pages with browser': '' + function(browser) {

    browser
      .url('http://nightwatchjs.org')
      .waitForElementPresent('body', 10000)
      .assert.urlContains('nightwatchjs.org')

      .url('http://golem.de')
      .waitForElementPresent('body', 10000)
      .assert.urlContains('golem.de')

      .url('http://github.com')
      .waitForElementPresent('body', 10000)
      .assert.urlContains('github.com');
  },

// fails gracefully
'Attempt to load multiple pages w/ page objects': function(browser) {

    var page = browser.page.Google();

    page
      .navigate()  // http://google.com set as url property in page-object
      .waitForElementPresent('body', 10000)
      .assert.urlContains('google.com')
      .api.perform(function() {
        page.url = function() { return 'http://nightwatchjs.org'; };
      });

    page
      .navigate()
      .waitForElementPresent('body', 10000)
      .assert.urlContains('nightwatchjs.org')

      .api.perform(function() {
        page.url = 'http://github.com';
      })
      .waitForElementPresent('body', 10000)
      .assert.urlContains('github.com');
  }
};

I could not find a way to update the url property of a page-object.
@beatfactor maybe you can shed some light ?

I'm having this same issue with dynamic URLs.

The way its implemented now is that urls are evaluated at page object creation, not at time of navigate. Re-defining the value of url in the middle of the test will not alter the outcome of the url and will instead fail due to the fact that the value of url at that point is expected to be a string (resolved from string or function on creation) rather than a function.
