These are steps to setup a new project in ROR.
You must configure and install your Gems individually instead of copying the Gemfile from a previous project.

Refer to Heroku setup if you want to push your project to Heroku.

Setup directory

# Create directory in ~/workspace
mkdir ./testproject
cd ./testproject

Test driven development

Write failing test case first (RED)

• Write test cases strictly to expose core functions and errors
• Your test cases guard your app from future changes
• Test cases also tells how your app works
• Think about how other codes will impact your code
• Test cases test on the coding's behavior, not implementation.

Write the simplest code to satisfy test case (GREEN)
