Rspec with guard without rails

one liner about rspec and guard

Rspec - RSpec is testing tool for the Ruby programming language. It is designed to make Test-Driven Development a productive and enjoyable experience.
More @ http://rspec.info/

Guard - Guard is a command line tool to easily handle events on file system modifications. So you don't have to run the test each and every time when you change the files. Guard keeps you focus on the tests and text editor or IDE.

The simple way

Step:1 - Clone the project

$git clone git://github.com/mohanraj-nagasamy/rspec-test.git

Step:2 - Run the following commands

$cd rspec-test
$ls -l

lib - is where your source goes.
spec - is where your tests goes (RSpec files)

Step:3 - Install rspec

Now install the rspec gem if you haven't installed yet. Try rspec -v to test it.

$gem install rspec

Step:4 - Install guard

Now install the guard gem if you haven't installed yet. Try guard -v to test it.

$gem install guard

Step:5 - Run the guard

$guard -i -n f -c

It will watch for the file changes and runs the test for you. You don't have to run the tests every time when you change the files (including tests and the file you are testing).

Step:6 - Open the code in some editor

$subl . #Sublime in my case

Stay focus on the editor and keep writing tests.

Step:7 - Have fun

Remember:
lib - is where your source goes.
spec - is where your tests goes (RSpec files).
And the movie memento - TDD is kind of that exp.

The manual way

Some people want to do it by manually on their own. So here are the steps.
But you may have to modify the following files or copy from - https://github.com/mohanraj-nagasamy/rspec-test.git

.rspec
Guardfile

Step:1 - create dirs

$mkdir rspec-test/{lib,spec}
$cd rspec-test

The folder structure will look like-

$rspec-test
	-lib
	-spec

lib - is where your source goes.
spec - is where your tests goes (RSpec files)

Step:2 - Install rspec gem

now install the rspec gem if you haven't installed yet. Try rspec -v to test it.

$gem install rspec

$rspec --init #It will create .rspec file and spec_helper.rb.

Copy fine tuned from - https://github.com/mohanraj-nagasamy/rspec-test.git

Step:3 - Create test first

Let's say you want to test User spec. Create user_spec.rb inside spec dir

$subl spec/user_spec.rb #open file

#spec/user_spec.rb 
require 'user'

describe User do
	it "should be equal" do
		user = User.new
		user.name = "test-1"
		user.name.should be == "test-1"
	end
end

Step:4 - Create something to fail/pass the test

create user.rb inside lib dir

$subl lib/user.rb 

#lib/user.rb 

class User
	attr_accessor :name
end

Step:5 - Run tests with rspec

$rspec spec/user_spec.rb -f d -c

You should be able to see the test running successfully.

Step:6 - Let's automate with guard.

Install the guard gem if you haven't installed yet. Try guard -v to test it.

$gem install guard

$guard init # This is will create Guardfile.

You may not need all the contents so copy Guardfile from - https://github.com/mohanraj-nagasamy/rspec-test.git

Step:7 - Run the guard

$guard -i -n f -c

It will watch for the file changes and runs the test for you. You don't have to run the tests every time when you change the files (including tests and the file you are testing).

Step:8 - Open the code in some editor

$subl . #Sublime in my case

Stay focus on the editor and keep writing tests.

Step:9 - Have fun

Remember:
lib - is where your source goes.
spec - is where your tests goes (RSpec files).
And the movie memento - TDD is kind of that exp.
