Fixture, a simple fixture for rspec and others

What is it?

####It

is a very simple and lightweight fixture easy to use
can be used under various situations
requires no other libraries

Installation

gem install fixture

How to use

####write fixture

#spec/fixtures.rb

Fixture.manage User do
  assign :user1 do
    name 'Taro Yamada'
	email { #this is a block }
	created_at Time.now
  end

  assign :user2 do
    name { Faker::Name.name + 's' }
    email Faker::Internet.email
    deleted true
  end
end

Fixture.manage Post do
  assign :post1 do
    title 'title1'
	body '....'
	user_id { Fixture.get(:user1).id }
  end
end

Of cource, you can add many records at once by like this.

#####use faker

require 'faker'
Fixture.manage User do
  1000.times do |i|
    assign "user#{i+1}".to_sym do
      name  Faker::Name.name
      email Faker::Internet.email   
    end
  end
end

#####use csv file

require 'csv'
Fixture.manage User do
  CSV.read('path/to/data.csv').each.with_index(1) do |row, i|
    assign :"user#{i}" do
      name row[0] 
      email row[1]
    end
  end
end

And you can put it as separate files in other directory.

Fixture automatically loads

spec/fixtures.rb
spec/fixtures/*.rb
test/fixtures.rb
test/fixtures/*.rb

####load fixture

#spec/spec_helper.rb
require 'fixture'	
Fixture.load

if you don't want to insert records but use model's instances,

Fixture.prepare

instead of Fixture.load.

####use fixture

#spec/models/user_spec.rb

describe User do
  let (:user) { Fixture.get(:user2) }
.....

##Assumption

Fixture assumes that model classes

have accessor methods to each attributes(i.e; columns of record)
have save! or save method to insert new record
