Test Refactor: Setting up FactoryBot and Contexts Module

[PeterNotFound114]

Overview

This PR proposes a new testing framework for Binder using the Factory Pattern provided by FactoryBot to create test instances, and the module system to organize test objects into module Contexts. This is consistent with patterns used throughout the course Application Design and Development (67-272).

Deliverables

• Automated factory generation with scripts that parses db/schema.rb to get all columns and associations from DB schema (in case migration changes / new migrations are added)
• Factory files generated via scripts
• Set files and contexts.rb file under test/ outlining general structure of test object creation

Next Steps

• Rename all non-FK columns that ends with "_id"
• Migrate fixture objects to objects created using FactoryBot
• Explore possibilities of automated ERD generation using similar scripts as the one parsing the schema file
