## This script can be used to detect simple order dependencies if one of tests is failing when some other test(or tests, independently) is being run before it.
## Script will not give reliable results if the dependency is complex - e.g. two specific tests must be run before for affected one to fail.
## Script will refine results with each rspec run: more runs will result smaller UNSAFE lists. Files from previous script runs are used too

## Ensure that you have config.order = 'random' in RSpec.configure block .

## Running rspec with different seeds to collect data
RSPEC_RUN_COUNT = 5 #set to 0 to analyze already existing rspec_*.txt files

RSPEC_RUN_COUNT.times do

# This is a skeleton for testing models including examples of validations, callbacks,

# Pick and choose what you want, as all models don't NEED to be tested at this depth.

# I'm always eager to hear new tips & suggestions as I'm still new to testing,

This is a small collection of scripts showing how to use require.js. It's only one of several ways of setting up a require.js project, but it's enough to get started.

At its core, require.js is about three things:

1. Dependency management
2. Modularity
3. Dynamic script loading

The following files show how these are achieved.
