AwesomeCo is a test data seeding harness, that can seed test data into a user or group namespace.

AwesomeCo uses FactoryBot in the backend which makes maintenance extremely easy. When a Model is changed, FactoryBot will already be reflected to account for the change.

Docker Setup

See AwesomeCo Docker Demo

GDK Setup

$ gdk start db
ok: run: services/postgresql: (pid n) 0s, normally down
ok: run: services/redis: (pid n) 74s, normally down
$ bundle install
Bundle complete!
$ bundle exec rake db:migrate
main: migrated
ci: migrated


The ee:gitlab:seed:awesome_co Rake task takes two arguments. :name and :namespace_id.

$ bundle exec rake "ee:gitlab:seed:awesome_co[awesome_co,1]"
Seeding AwesomeCo for Administrator


Where :name is the name of the AwesomeCo. (This will reflect .rb files located in db/seeds/awesome_co/*.rb)


Where :namespace_id is the ID of the User or Group Namespace

List of Awesome Companies

Each company (i.e. test data template) is represented as a Ruby file (.rb) in db/seeds/awesome_co.

AwesomeCo (db/seeds/awesome_co/awesome_co.rb)

$ bundle exec rake "ee:gitlab:seed:awesome_co[awesome_co,:namespace_id]"
Seeding AwesomeCo for :namespace_id

AwesomeCo is an automated seeding of this demo repository.


AwesomeCo seeding uses FactoryBot definitions from spec/factories which …

  1. Saves time on development
  2. Are easy-to-read
  3. Are easy to maintain
  4. Do not rely on an API that may change in the future
  5. Are always up-to-date
  6. Execute on the lowest-level (ActiveRecord) possible to create data as quickly as possible

From the FactoryBot README : factory_bot is a fixtures replacement with a straightforward definition syntax, support for multiple build strategies (saved instances, unsaved instances, attribute hashes, and stubbed objects), and support for multiple factories for the same class, including factory inheritance

Factories reside in spec/factories/* and are fixtures for Rails models found in app/models/*. For example, For a model named app/models/issue.rb, the factory will be named spec/factories/issues.rb. For a model named app/models/project.rb, the factory will be named app/models/projects.rb.

Taxonomy of a Factory

Factories consist of three main parts - the Name of the factory, the Traits and the Attributes.

Given: create(:iteration, :with_title, :current, title: 'My Iteration')

:iteration This is the Name of the factory. The file name will be the plural form of this Name and reside under either spec/factories/iterations.rb or ee/spec/factories/iterations.rb.
:with_title This is a Trait of the factory. See how it’s defined.
:current This is a Trait of the factory. See how it’s defined.
title: ‘My Iteration’ This is an Attribute of the factory that will be passed to the Model for creation.


In these examples, you will see an instance variable @owner. This is the root user (User.first).

Create a Group

my_group = create(:group, name: 'My Group', path: 'my-group-path')

Create a Project

# create a Project belonging to a Group
my_project = create(:project, :public, name: 'My Project', namespace: my_group, creator: @owner)

Create an Issue

# create an Issue belonging to a Project
my_issue = create(:issue, title: 'My Issue', project: my_project, weight: 2)

Create an Iteration

# create an Iteration under a Group
my_iteration = create(:iteration, :with_title, :current, title: 'My Iteration', group: my_group)

Frequently encountered issues

ActiveRecord::RecordInvalid: Validation failed: Email has already been taken, Username has already been taken

This is because, by default, our factories are written to backfill any data that is missing. For instance, when a project is created, the project must have somebody that created it. If the owner is not specified, the factory attempts to create it.

How to fix

Check the respective Factory to find out what key is required. Usually :author or :owner.

# This throws ActiveRecord::RecordInvalid
create(:project, name: 'Throws Error', namespace: create(:group, name: 'Some Group'))

# Specify the user where @owner is a [User] record
create(:project, name: 'No longer throws error', owner: @owner, namespace: create(:group, name: 'Some Group'))
create(:epic, group: create(:group), author: @owner)
