An introduction to set up a good testing environment in Ruby on Rails 4
My understanding of continuous testing is that, there is a testing tool in the background, which while developing and modifying code, it will continuously notify you the broken of correct code. I usually set up the testing environment using `RSpec`, `Spork` and `Guard`. The setup process may easily go wrong. Thus I made a note of the process.
I found many developers being confused by all the levels of testing in Rails, and some concepts in software testing. Rails community has a very very strong awareness of TDD, and even BDD. Apps are designd using an Outside-in approach, which makes me feel really comfortable and also effective.
In order to do unit testing easier, one should keep a word in mind: Isolation. Try your best to isolate the irrelevant things from your class, and make them easy to config.
