This document discusses the importance of good design principles for test automation code. It provides examples of applying basic design concepts like avoiding duplication and separating concerns when automating tests using the Robot Framework and Selenium. The examples start simply by extracting duplicated steps in a single test into keywords and variables. They progress to splitting functionality across multiple files as "resources" and parameterizing tests to run with different data values. The goal is to demonstrate how non-programmers can design maintainable automated tests by applying basic coding best practices.
