# Skyforge

Forge mock objects for your test with immense power! This one is currently in development, 
and not close to being done. So what are we planning to do here?

## !!! THIS IS THEORETICAL, UNDER CONSTRUCTION !!!

## Trace

Using Mockingjay, trace a ruby hash to make a generator for more objects like it.

# Playing off of my prompt idea, let's take it one step further:

name = prompt for: 'Name', validate: { with: /\w+/, or: 'Invalid name given!' }

# Where if given invalid input it will say:
# Error: Invalid name given
# Name:
