How to use RSpec and ZenTest in a standalone Ruby project
First install the RSpec and ZenTest gem:
$ sudo gem install rspec zentest
Next create the spec folder:
$ cd project_folder
$ mkdir spec
Save the following to spec/helper.rb:
$LOAD_PATH.unshift File.dirname(__FILE__) + '/..'
require 'rubygems'
require 'spec'
#require 'spec/rake/spectask' not needed, because ZenTest supports rspec now
Now create spec/transcoder_spec.rb, and add the following test to it:
require File.dirname(__FILE__) + '/helper'
require File.dirname(__FILE__) + '/../transcoder.rb'
context "Transcoder" do
setup do
# Setup your stuff here
end
it "should support 3gp format" do
Transcoder.convert("me_and_you.3gp").should == true
end
end
Let's not forget the class we're testing, put this code in lib/transcoder.rb:
class Transcoder
def initialize
end
def self.convert(file)
return true
end
end
Note that autotest automatically looks for your code in the lib folder.
Now run the test with the zentest command:
autotest
Change your files and autotest will run the test again.
