mattscilipoti-model_steps

Attempt to answer 4 needs:

  1. Support creation of models with attributes

  2. Uniquely identify models in cucumber steps

  3. Reference associated models

  4. Support factory derivations i.e. user_admin, user_manager

Attempt:

Assume:

User belongs_to Organization
User has_many Courses
Course belongs_to Topic
User has_friendly_id :login

Note: it is dependent on friendly_id: http://github.com/norman/friendly_id

General: a step that ends in colon (:) expects a cucumber table.

  1. Support creation of models with attributes

Given these Users exist:
  |login  |first_name |last_name |
  |tester |joe        |tester    |
  |anon   |John       |Doe       |
  * only one row is required.  Works the same for one, or more, rows.

This will call:
  Factory(:user, :login => 'tester', :first_name => 'joe', :last_name => 'tester')
  Factory(:user, :login => 'anon', :first_name => 'John', :last_name => 'Doe')

Comparison:
pickle:
  Single:    
     Given a user exists with login: "tester", first_name: "joe", last_name: "tester"

  Multiple:
  Given the following Users exist
    |login  |first_name |last_name |
    |tester |joe        |tester    |
    |anon   |John       |Doe       |

factory_girl:
  Given
  1. Uniquely identify models in cucumber steps

Model:friendly_id
User:Matt

Possible options:
  User:"Matt"
  User|matt
  1. Reference associated models

A. utilize associations in tables
  Given these people exist:
  |name |organization |
  |Matt |Dept. A|

This will identify that 'role' is an association and perform the equivalent of:
   Role.find_by_name('Admin') || Factory(:role, :name => 'Admin') #using Factory(:role, Topic.friendly_column_name => 'Admin')

B. ModelA has many ModelBs
  Given User:Matt has these Courses:
    |name  |topic   |
    |B101  |Biology |
    |CS101 |CompSci |

  Executes:  
    Factory(:user, :course => :name => 'B101', :topic => Topic.find('Biology') || Factory(:topic, Topic.friendly_column_name => 'biology'))
    Factory(:user, :course => :name => 'CS101', :topic => Topic.find('CompSci'))
  1. Support factory derivations i.e. user_admin, user_manager

Given this User(Admin) exists:
  |first_name |
  |Jane       |

Executes:
  Factory(:user_admin, :name => 'Jane')

Given a User(with associations) exists

Executes:
  Factory(:user_with_associations)

Note on Patches/Pull Requests

  • Fork the project.

  • Make your feature addition or bug fix.

  • Add tests for it. This is important so I don't break it in a future version unintentionally.

  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but

    bump version in a commit by itself I can ignore when I pull)
  • Send me a pull request. Bonus points for topic branches.

Thanks for your help and patches!
