Define Sections

Sometimes it is useful to define sections of a page. Sections do 2 things:

  • Provide a level of namespacing under the page
  • Provide element-level nesting so that any element defined within a section is a descendant of its parent section in the DOM

Declare sections

You can create sections using the sections property:

nightwatch/pages/samplePage.js
module.exports = {
  sections: {
    menu: {
      selector: '#gb',
      elements: {
        mail: {
          selector: 'a[href*="mail"]'
        },
        images: {
          selector: 'a[href*="imghp"]'
        }
      }
    }
  }
};

Using sections in tests

Your tests would use it as follows:

tests/sampleTest.js
describe('sample test with page objects', function() {
  it('Test', function (browser) {
    var google = browser.page.google();
    google.expect.section('@menu').to.be.visible;
    
var menuSection = google.section.menu; menuSection.expect.element('@mail').to.be.visible; menuSection.expect.element('@images').to.be.visible;
menuSection.click('@mail');
browser.end(); }); });

Note that every command and assertion on a section (other than expect assertions) returns that section for chaining. If desired, you can nest sections under other sections for complex DOM structures.

Nesting page object sections

nightwatch/pages/samplePage.js
module.exports = {
  sections: {
    menu: {
      selector: '#gb',
      elements: {
        mail: {
          selector: 'a[href*="mail"]'
        },
        images: {
          selector: 'a[href*="imghp"]'
        }
      },
      sections: {
        apps: {
          selector: 'div.gb_pc',
          elements: {
            myAccount: {
              selector: '#gb192'
            },
            googlePlus: {
              selector: '#gb119'
            }
          }
        }
      }
    }
  }
};

Using a nested section in your test is straightforward:
tests/sampleTest.js
describe('sample test with page objects', function() {
  it('Test', function (browser) {
    var google = browser.page.google();
    google.expect.section('@menu').to.be.visible;
    
var menuSection = google.section.menu; var appSection = menuSection.section.apps; menuSection.click('@appSection');
appSection.expect.element('@myAccount').to.be.visible; appSection.expect.element('@googlePlus').to.be.visible;
browser.end(); }); });
