Process

Approach:

• Broke the task down into clear user stories
• Used TDD (red, green, refactor) to work through each story (as evidenced by my commits)
• Started with feature tests and broke these down into more focused unit tests
• Planned classes carefully to ensure I adhered to the Single Responsibility Principle
• Ensured tests were isolated from other classes to remove any external dependencies from individual spec files
