Rspec

Ruby Behavior driven development is Rpec. We will explore how to write specs with rspecs .


 we will not use yml fixture . yml fixtures sucks instead we use machinist and will use mocha as mocking framework

I assume you are on Mac or Linux .

First install rspec

sudo gem install rspec

then install rpsec-rails

sudo gem install rspec-rails

rails my_app

cd my_app

ruby script/generate rspec

cd spec

spec folder is home folder for all of you spec data for you app
