Page Object properties

• We have pages, elements, sections and commands properties under ./lib directory. They are the page object properties required by nightwatch.js. For more information on how to define them please refer this.
• page is the highest level page object property, defined base on one particular page.
• One page can have multiple sections.
• It is useful to define sections of a page. Sections do two things:
  1. Provide a level of namespacing under the page
  2. Provide element-level nesting so that any element defined within a section is a descendant of its parent section in the DOM
• elements are the places that your tests will interact with through commands and assertions on each page. This is made simple using the elements property so that all your elements are defined in a single place.
• You can add commands to your page object using the commands property. This is a useful way to encapsulate logic about the page that would otherwise live in a test, or multiple tests.
• command will be called in the context of the page or section where it is defined.
