Initial import of Radiant 0.9.1, which is now packaged as a gem. This is an
import of the tagged 0.9.1 source checked out from GitHub, which isn't quite
the same as the gem distribution - but it doesn't seem to be available in an
archived form and the installed gem already has modifications, so this is
the closest I can get.

| 1 | = Dataset |
| 2 | |
| 3 | Dataset provides a simple API for creating and finding sets of data in your database. Check out Dataset::RecordMethods and Dataset::ModelFinders. |
| 4 | |
| 5 | Dataset loads data intelligently if you use 'nested contexts' in your tests (RSpec, anything that uses Test::Unit::TestCase subclassing for creating nested contexts): |
| 6 | |
| 7 | describe Something do |
| 8 | dataset :a => Dataset :a is loaded (at the right time) |
| 9 | |
| 10 | it 'should whatever' |
| 11 | end |
| 12 | |
| 13 | describe More do |
| 14 | dataset :b => Dataset :b is loaded. :a data is still there |
| 15 | |
| 16 | it 'should' |
| 17 | end |
| 18 | end |
| 19 | |
| 20 | describe Another do => Database is restored to :a, without re-running :a logic |
| 21 | it 'should' |
| 22 | end |
| 23 | end |
| 24 | end |
| 25 | |
| 26 | The goal is to see a marked improvement in overall test run speed, basing this on the assumption that it is faster to have the OS copy a file or mySQL dump and load. Of course, we may find this to be a false assumption, but there were plenty of bugs in the former 'Scenarios' - addressing that afforded the opportunity to test the assumption. |

| 28 | |
| 29 | Dataset does not prevent you from using other libraries like Machinist or factory_girl. If you were to used either of those, you could have a dataset like this: |
| 30 | |
| 31 | require 'faker' |
| 32 | |
| 33 | class OrganizationsDataset < Dataset::Base |
| 34 | Sham.name { Faker::Name.name } |
| 35 | |
| 36 | Organization.blueprint do |
| 37 | name { Sham.name } |
| 38 | end |
| 39 | |
| 40 | def load |
| 41 | name_model Organization.make, :org_one |
| 42 | end |
| 43 | end |
| 44 | |
| 45 | The benefit is that you can reuse interesting sets of data, without sacrificing the utility of those other libraries. |
| 46 | |
| 47 | describe Organization, 'stuff' do |
| 48 | dataset :organizations |
| 49 | end |
| 50 | |
| 51 | describe Organization, 'other stuff' do |
| 52 | dataset :organizations |
| 53 | end |
| 54 | |
| 55 | |
| 56 | Get things installed, then read more in the Dataset documentation at http://aiwilliams.github.com/dataset |

| 59 | == Installation |
| 60 | |
| 61 | Install the plugin: |
| 62 | |
| 63 | ./script/plugin install git://github.com/aiwilliams/dataset.git |
| 64 | |
| 65 | In your test_helper.rb/spec_helper.rb: |
| 66 | |
| 67 | require 'dataset' |
| 68 | class Test::Unit::TestCase |
| 69 | include Dataset |
| 70 | datasets_directory "#{RAILS_ROOT}/spec/datasets" |
| 71 | end |
| 72 | |
| 73 | If you don't use rspec_on_rails, or you have specs that aren't of the RailsExampleGroup type, you should do this in spec_helper.rb: |
| 74 | |
| 75 | require 'dataset' |
| 76 | class Spec::Example::ExampleGroup |
| 77 | include Dataset |
| 78 | datasets_directory "#{RAILS_ROOT}/spec/datasets" |
| 79 | end |
| 80 | |
| 81 | If you were a user of the Scenarios plugin, and want to do as little as possible to get going (assumes you are using rspec_on_rails): |
| 82 | |
| 83 | require 'dataset' |
| 84 | Scenario = Scenarios = Dataset |
| 85 | class Test::Unit::TestCase |
| 86 | include Dataset |
| 87 | class << self |
| 88 | alias_method :scenario, :dataset |
| 89 | end |
| 90 | end |
| 91 | class ScenariosResolver < Dataset::DirectoryResolver |
| 92 | def suffix |
| 93 | @suffix ||= 'Scenario' |
| 94 | end |
| 95 | end |
| 96 | Dataset::Resolver.default = ScenariosResolver.new("#{RAILS_ROOT}/spec/scenarios") |
| 97 | |
