Use the power of design patterns to solve different software automation related problems - Python

• Hide bad APIs behind better ones
• Automation related: represent each page (including elements and action over them) of an application as an object

• Targeted app: https://www.youtube.com
• Implement base page:
  • Currently supported:
    • open/quit the browser
    • wait for elements to be visible
  • Feature methods:
    • generic validator
    • different clicks
• Each new page created will extend the base class
• Implement a search for a video as example:
  • enter a string to query e.g. Python
  • click on search button
  • filter result list based on a keyword e.g. Python
  • select the video found based on this query
• In tests section, under page_object_pattern package, two tests are performed:
  • a simple one to perform the wait for element action from base class
  • a search flow
  • note that from now on the test implementation is hidden in a specific page;
  • to perform some tests, you just have to call different page specific methods

###Summery

• Creational design pattern.
• Provides an easy way to create a single instance of an object.

###Example

• Access the same instance of the driver session class.

1. The entire definition of the object class is encapsulated in the builder class:

   • The outer class exposes a method that returns the instance of the inner class.

2. Design a class that handles the instantiation.

   • Inject the definition of the desired class in the singleton factory and the factory is responsible for returning the same instance.
