+# Factory objects in GitLab QA
+
+In GitLab QA we are using factories to create resources.
+
+Factories implementation are primarily done using Browser UI steps, but can also
+be done via the API.
+
+## Why do we need that?
+
+We need factory objects because we need to reduce duplication when creating
+resources for our QA tests.
+
+## How to properly implement a factory object?
+
+All factories should inherit from [`Factory::Base`](./base.rb).
+
+There is only one mandatory method to implement to define a factory. This is the
+`#fabricate!` method, which is used to build a resource via the browser UI.
+Note that you should only use [Page objects](../page/README.md) to interact with
+a Web page in this method.
+
+Here is an imaginary example:
+
+```ruby
+module QA
+  module Factory
+    module Resource
+      class Shirt < Factory::Base
+        attr_accessor :name, :size
+
+        def initialize(name)
+          @name = name
+        end
+
+        def fabricate!
+          Page::Dashboard::Index.perform do |dashboard_index|
+            dashboard_index.go_to_new_shirt
+          end
+
+          Page::Shirt::New.perform do |shirt_new|
+            shirt_new.set_name(name)
+            shirt_new.create_shirt!
+          end
+        end
+      end
+    end
+  end
+end
+```
+
+### Define API implementation
+
+A factory may also implement the three following methods to be able to create a
+resource via the public GitLab API:
+
+- `#api_get_path`: The `GET` path to fetch an existing resource.
+- `#api_post_path`: The `POST` path to create a new resource.
+- `#api_post_body`: The `POST` body (as a Ruby hash) to create a new resource.
+
+Let's take the `Shirt` factory example, and add these three API methods:
+
+```ruby
+module QA
+  module Factory
+    module Resource
+      class Shirt < Factory::Base
+        attr_accessor :name, :size
+
+        def initialize(name)
+          @name = name
+        end
+
+        def fabricate!
+          Page::Dashboard::Index.perform do |dashboard_index|
+            dashboard_index.go_to_new_shirt
+          end
+
+          Page::Shirt::New.perform do |shirt_new|
+            shirt_new.set_name(name)
+            shirt_new.create_shirt!
+          end
+        end
+
+        def api_get_path
+          "/shirt/#{name}"
+        end
+
+        def api_post_path
+          "/shirts"
+        end
+
+        def api_post_body
+          {
+            name: name
+          }
+        end
+      end
+    end
+  end
+end
+```
+
+The [`Project` factory](./resource/project.rb) is a good real example of Browser
+UI and API implementations.
+
+### Define dependencies
+
+A resource may need an other resource to exist first. For instance, a project
+needs a group to be created in.
+
+To define a dependency, you can use the `dependency` DSL method.
+The first argument is a factory class, then you should pass `as: <name>` to give
+a name to the dependency.
+That will allow access to the dependency from your resource object's methods.
+You would usually use it in `#fabricate!`, `#api_get_path`, `#api_post_path`,
+`#api_post_body`.
+
+Let's take the `Shirt` factory, and add a `project` dependency to it:
+
+```ruby
+module QA
+  module Factory
+    module Resource
+      class Shirt < Factory::Base
+        attr_accessor :name, :size
+
+        dependency Factory::Resource::Project, as: :project do |project|
+          project.name = 'project-to-create-a-shirt'
+        end
+
+        def initialize(name)
+          @name = name
+        end
+
+        def fabricate!
+          project.visit!
+
+          Page::Project::Show.perform do |project_show|
+            project_show.go_to_new_shirt
+          end
+
+          Page::Shirt::New.perform do |shirt_new|
+            shirt_new.set_name(name)
+            shirt_new.create_shirt!
+          end
+        end
+
+        def api_get_path
+          "/project/#{project.path}/shirt/#{name}"
+        end
+
+        def api_post_path
+          "/project/#{project.path}/shirts"
+        end
+
+        def api_post_body
+          {
+            name: name
+          }
+        end
+      end
+    end
+  end
+end
+```
+
+**Note that dependencies are always built via the API fabrication method if
+supported by their factories.**
+
+### Define attributes on the created resource
+
+Once created, you may want to populate a resource with attributes that can be
+found in the Web page, or in the API response.
+For instance, once you create a project, you may want to store its repository
+SSH URL as an attribute.
+
+To define an attribute, you can use the `product` DSL method.
+The first argument is the attribute name, then you should define a name for the
+dependency to be accessible from your resource object's methods.
+
+Let's take the `Shirt` factory, and define a `:brand` attribute:
+
+```ruby
+module QA
+  module Factory
+    module Resource
+      class Shirt < Factory::Base
+        attr_accessor :name, :size
+
+        dependency Factory::Resource::Project, as: :project do |project|
+          project.name = 'project-to-create-a-shirt'
+        end
+
+        # Attribute populated from the Browser UI (using the block)
+        product :brand do
+          Page::Shirt::Show.perform do |shirt_show|
+            shirt_show.fetch_brand_from_page
+          end
+        end
+
+        def initialize(name)
+          @name = name
+        end
+
+        def fabricate!
+          project.visit!
+
+          Page::Project::Show.perform do |project_show|
+            project_show.go_to_new_shirt
+          end
+
+          Page::Shirt::New.perform do |shirt_new|
+            shirt_new.set_name(name)
+            shirt_new.create_shirt!
+          end
+        end
+
+        def api_get_path
+          "/project/#{project.path}/shirt/#{name}"
+        end
+
+        def api_post_path
+          "/project/#{project.path}/shirts"
+        end
+
+        def api_post_body
+          {
+            name: name
+          }
+        end
+      end
+    end
+  end
+end
+```
+
+#### Inherit a factory's attribute
+
+Sometimes, you want a resource to inherit its factory attributes. For instance,
+it could be useful to pass the `size` attribute from the `Shirt` factory to the
+created resource.
+You can do that by defining `product :attribute_name` without a block.
+
+Let's take the `Shirt` factory, and define a `:name` and a `:size` attributes:
+
+```ruby
+module QA
+  module Factory
+    module Resource
+      class Shirt < Factory::Base
+        attr_accessor :name, :size
+
+        dependency Factory::Resource::Project, as: :project do |project|
+          project.name = 'project-to-create-a-shirt'
+        end
+
+        # Attribute inherited from the Shirt factory if present,
+        # or from the Browser UI otherwise (using the block)
+        product :brand do
+          Page::Shirt::Show.perform do |shirt_show|
+            shirt_show.fetch_brand_from_page
+          end
+        end
+
+        # Attribute inherited from the Shirt factory if present,
+        # or a QA::Factory::Product::NoValueError is raised otherwise
+        product :name
+        product :size
+
+        def initialize(name)
+          @name = name
+        end
+
+        def fabricate!
+          project.visit!
+
+          Page::Project::Show.perform do |project_show|
+            project_show.go_to_new_shirt
+          end
+
+          Page::Shirt::New.perform do |shirt_new|
+            shirt_new.set_name(name)
+            shirt_new.create_shirt!
+          end
+        end
+
+        def api_get_path
+          "/project/#{project.path}/shirt/#{name}"
+        end
+
+        def api_post_path
+          "/project/#{project.path}/shirts"
+        end
+
+        def api_post_body
+          {
+            name: name
+          }
+        end
+      end
+    end
+  end
+end
+```
+
+#### Define an attribute based on an API response
+
+Sometimes, you want to define a resource attribute based on the API response
+from its `GET` or `POST` request. For instance, if the creation of a shirt via
+the API returns
+
+```ruby
+{
+  brand: 'a-brand-new-brand',
+  size: 'extra-small',
+  style: 't-shirt',
+  materials: [[:cotton, 80], [:polyamide, 20]]
+}
+```
+
+you may want to store `style` as-is in the resource, and fetch the first value
+of the first `materials` item in a `main_fabric` attribute.
+
+For both attributes, you will need to define an inherited attribute, as shown
+in "Inherit a factory's attribute" above, but in the case of `main_fabric`, you
+will need to implement the
+`#transform_api_resource` method to first populate the `:main_fabric` key in the
+API response so that it can be used later to automatically populate the
+attribute on your resource.
+
+If an attribute can only be retrieved from the API response, you should define
+a block to give it a default value, otherwise you could get a
+`QA::Factory::Product::NoValueError` when creating your resource via the
+Browser UI.
+
+Let's take the `Shirt` factory, and define a `:style` and a `:main_fabric`
+attributes:
+
+```ruby
+module QA
+  module Factory
+    module Resource
+      class Shirt < Factory::Base
+        attr_accessor :name, :size
+
+        dependency Factory::Resource::Project, as: :project do |project|
+          project.name = 'project-to-create-a-shirt'
+        end
+
+        # Attribute fetched from the API response if present if present,
+        # or from the Shirt factory if present,
+        # or from the Browser UI otherwise (using the block)
+        product :brand do
+          Page::Shirt::Show.perform do |shirt_show|
+            shirt_show.fetch_brand_from_page
+          end
+        end
+
+        # Attribute fetched from the API response if present if present,
+        # or from the Shirt factory if present,
+        # or a QA::Factory::Product::NoValueError is raised otherwise
+        product :name
+        product :size
+        product :style do
+          'unknown'
+        end
+        product :main_fabric do
+          'unknown'
+        end
+
+        def initialize(name)
+          @name = name
+        end
+
+        def fabricate!
+          project.visit!
+
+          Page::Project::Show.perform do |project_show|
+            project_show.go_to_new_shirt
+          end
+
+          Page::Shirt::New.perform do |shirt_new|
+            shirt_new.set_name(name)
+            shirt_new.create_shirt!
+          end
+        end
+
+        def api_get_path
+          "/project/#{project.path}/shirt/#{name}"
+        end
+
+        def api_post_path
+          "/project/#{project.path}/shirts"
+        end
+
+        def api_post_body
+          {
+            name: name
+          }
+        end
+
+        private
+
+        def transform_api_resource(api_response)
+          api_response[:main_fabric] = api_response[:materials][0][0]
+          api_response
+        end
+      end
+    end
+  end
+end
+```
+
+**Notes on attributes precedence:**
+
+- attributes from the API response take precedence over attributes from the
+  factory (i.e inherited)
+- attributes from the factory (i.e inherited) take precedence over attributes
+  from the Browser UI
+- attributes without a value will raise a `QA::Factory::Product::NoValueError` error
+
+## Creating resources in your tests
+
+To create a resource in your tests, you can call the `.fabricate!` method on the
+factory class.
+Note that if the factory supports API fabrication, this will use this
+fabrication by default.
+
+Here is an example that will use the API fabrication method under the hood since
+it's supported by the `Shirt` factory:
+
+```ruby
+my_shirt = Factory::Resource::Shirt.fabricate!('my-shirt') do |shirt|
+  shirt.size = 'small'
+end
+
+expect(page).to have_text(my_shirt.brand) # => "a-brand-new-brand" from the API response
+expect(page).to have_text(my_shirt.name) # => "my-shirt" from the inherited factory's attribute
+expect(page).to have_text(my_shirt.size) # => "extra-small" from the API response
+expect(page).to have_text(my_shirt.style) # => "t-shirt" from the API response
+expect(page).to have_text(my_shirt.main_fabric) # => "cotton" from the (transformed) API response
+```
+
+If you explicitely want to use the Browser UI fabrication method, you can call
+the `.fabricate_via_browser_ui!` method instead:
+
+```ruby
+my_shirt = Factory::Resource::Shirt.fabricate_via_browser_ui!('my-shirt') do |shirt|
+  shirt.size = 'small'
+end
+
+expect(page).to have_text(my_shirt.brand) # => the brand name fetched from the `Page::Shirt::Show` page
+expect(page).to have_text(my_shirt.name) # => "my-shirt" from the inherited factory's attribute
+expect(page).to have_text(my_shirt.size) # => "small" from the inherited factory's attribute
+expect(page).to have_text(my_shirt.style) # => "unknown" from the attribute block
+expect(page).to have_text(my_shirt.main_fabric) # => "unknown" from the attribute block
+```
+
+You can also explicitely use the API fabrication method, by calling the
+`.fabricate_via_api!` method:
+
+```ruby
+my_shirt = Factory::Resource::Shirt.fabricate_via_api!('my-shirt') do |shirt|
+  shirt.size = 'small'
+end
+```
+
+In this case, the result will be similar to calling `Factory::Resource::Shirt.fabricate!('my-shirt')`.
