Udemy – Design and Build API Automation Framework from Scratch

In the course, I have first covered, how to automate HTTP Methods(Post, Put, Get and Delete) using plain Java code. Then I have covered  framework building by following layered approach, building the framework from bottom up.

I approach API Automation Framework Design using Bottom Up Layered Approach with following layers :

• Service Layer – Implement the HTTP Method Calls
• Model Layer – Define Request and Response Model Classes
• Helper Layer – Create Request Object and Call Service Layer Method Call
• Test Layer – Implement Test Cases and Use Helper Layer to Call APIs
• Data Layer – Provide Data to Tests using Data Providers
• Validation Layer – Implement Response Validation Methods for API
• Runner Layer –  Enable Test Runs via CLI Commands, and thus via CI/CD Tools
• Environment Layer – Enable Tests to Run on Multiple Environments
• Report Layer – Add Reporting and Logging for Test Runs

The layered approach helps the framework to be easy and quick to scale and maintain. This design approach can be applied to either Java or Python tech stack.
