### Copy over spec/support directory and add to rails_helper.rb:

require 'capybara/rails'
require 'capybara/rspec'
require "cancan/matchers"
require "paperclip/matchers"
```

### Uncomment

```
Dir[Rails.root.join('spec', 'support', '**', '*.rb')].each { |f| require f }
```

### Add in Rspec.config in rails helper
```
config.include OAuthHelper
  config.include FactoryBot::Syntax::Methods
  config.include Paperclip::Shoulda::Matchers

  # Filter lines from Rails gems in backtraces.
  config.filter_rails_from_backtrace!
  # arbitrary gems may also be filtered via:
  # config.filter_gems_from_backtrace("gem name")

  # Uncomment if using VCR
  #VCR.configure do |c|
  #  c.allow_http_connections_when_no_cassette = true
  #  c.cassette_library_dir     = 'spec/cassettes'
  #  c.hook_into                :webmock
  #  #c.default_cassette_options = { record: :new_episodes }
  #  #c.ignore_hosts 'codeclimate.com'
  #end

  config.before :each do
    if Capybara.current_driver == :rack_test
      DatabaseCleaner.strategy = :transaction
    else
      DatabaseCleaner.strategy = :truncation
    end
    DatabaseCleaner.start
  end

  config.after do
    DatabaseCleaner.clean
  end
```

### Add in rails_helper.rb after Rspec.config do ... end

```
Shoulda::Matchers.configure do |config|
  config.integrate do |with|
    # Choose a test framework:
    with.test_framework :rspec
    #with.test_framework :minitest
    #with.test_framework :minitest_4
    #with.test_framework :test_unit

    # Choose one or more libraries:
    #with.library :active_record
    #with.library :active_model
    #with.library :action_controller
    # Or, choose the following (which implies all of the above):
    with.library :rails
  end
end

Capybara.default_max_wait_time = 8
```

## Add to users factory
```
factory :user do
    sequence(:email) {|n| "user#{n}@example.org" }
    password { 'blahblah' * 10 }
    after(:create) {|user| user.add_role(:person)}
  end
  factory :admin, class: User do
    sequence(:email) {|n| "admin#{n}@example.org" }
    password { 'blahblah'* 10 }
    after(:create) {|user| user.add_role(:admin)}
  end
```

### Add oauth factories
spec/factories/oauth_access_token.rb
```
FactoryBot.define do
  factory :oauth_access_token do
    association :resource_owner, factory: :user
    token { 'cabee01dead23beef89' }
    refresh_token { 'dead23beef89cabee01' }
    expires_in { 2592000 }
  end
end
```

app/models/oauth_access_token.rb
```
class OauthAccessToken < ApplicationRecord
  # needed for testing with FactoryGirl
end
```

spec/factories/oauth_application.rb
```
FactoryBot.define do
  factory :oauth_application do
    name { 'TestApp' }
    uid { 'TestApp' }
    secret { 'deadbeef' }
    redirect_uri { 'http://e7.com/help/mobile' }
  end
end
```

app/models/oauth_application.rb
```
class OauthApplication < ApplicationRecord
  # needed for testing with FactoryGirl
end
```

## seed file 
```
users = [
  { name:"Alexii Carey", email: "[email protected]", password: "MYPASSWORD", password_confirmation: "MYPASSWORD", role: :admin }
]

users.each do |user|
  User.find_or_initialize_by(email: user[:email]).tap do |u|
    u.name = user[:name]
    u.password = user[:password]
    u.password_confirmation = user[:password_confirmation]
    u.save!
    u.add_role user[:role]
  end
end

roles = [
  { name: 'admin' }
]
roles.each do |role|
  Role.find_or_initialize_by(name: role[:name]).tap do |r|
    r.name = role[:name]
    r.save!
  end
end

# Don't forget to add the uid and secret here. I ususally copy or generate new ones
oauth_applications = [
  { name: "Mobile App", uid: "", secret: "", redirect_uri:	"urn:ietf:wg:oauth:2.0:oob"	},
]

oauth_applications.each do |oauth|
  OauthApplication.find_or_initialize_by(uid: oauth[:uid]).tap do |oa|
    oa.name = oauth[:name]
    oa.secret = oauth[:secret]
    oa.redirect_uri = oauth[:redirect_uri]
    oa.save!
  end
end
```

rake db:seed
