[Refactoring proposal] Test app structure refactoring

Bắt đầu bằng cách đọc test/fixtures/active_record.rb và test_helper.rb để lập bản đồ schema, các model, controller, resource, route, cấu hình và monkey-patch mà chúng chứa. Tách từng loại component vào các file test được đề xuất và include chúng từ test_helper.rb. Hoàn thành khi ứng dụng test vẫn giữ nguyên hành vi và cấu trúc của nó khớp với bố cục được đề xuất.

Description

Currently, we put all kind of components of our test app in side test/fixtures/active_record.rb. It contains schema, models, controllers and resources. The file’s name is quite misleading since it contains more than active_record related stuffs. And it’s a 2000 lines file, a little bit too long.

And in the meantime, test_helper.rb has the routes, test configurations, monkey-patches and test app configurations.

As a new contributor, I need to spend more time to figure out the test setup under this structure.

So I suggest we can do a small refactoring, to extract and put different types of components into their own files. Like:

test 
 |——— schema.rb # for schema
 |——— models.rb # for models
 |——— controllers.rb # for controllers
 |——— resources.rb # for resources
 |——— routes.rb # for routes
 |——— app.rb # for app configs
 |——— test_helper.rb # test configs, monkey-patchings and requires

Now we can just include these component files inside test_helper.rb and it’ll be more easier for new contributors to understand the test app.
