My frontend is an EmberJS-based app. It's totally async in nature, so testing it with Capybara is pain and misery. On the other hand, Ember provides a fantastic test suite out of the box which makes acceptance testing fun and effective.
Normally, either fixtures or backend mocks are used to acceptance-test Ember apps. But testing against mocks does not satisfy me at all:
So I want to test against the real backend! It's trivial to set up Ember to use a local backend instance for testing. But the problem is that the backend will persist its state between individual tests and even test sessions.
That's why I'm thinking of implementing a special public API in Rails:
I'm a frontend dev with a sketchy knowledge of Rails. Factory Girl and Database Cleaner seem to be the right tools for the job, but there is absolutely no information how to use them outside Rails' normal test environment. I guess I need a controller or a Rails engine or something.
So the question is: how do I make an API in Rails that can be used by the frontend to tell Rails to set up a certain database state with a fixture factory, while Rails are running in a non-test mode i. e. serving REST API and not running through RSpec/Capybara/Cucumber?
Bonus feature: fixture factory properties should be defined on the frontend so that test code is stored in one place. Thus, the backend should be able to accept fixture factory properties via the special API. Defaults can still be defined in the backend's codebase.
I believe this could become an acceptance/integration testing best practice. If I manage to implement it, I promise to publish a gem.
API (application programming interface) testing is performed at the message layer without GUI. It is a part of integration testing that determines whether the APIs meet the testers' expectations of functionality, reliability, performance, and security.
Integration testing verifies the interface between two software units or modules. It focuses on checking if modules are communicating adequately and exposes any errors between integrated units.
Integration testing focuses on ensuring various components within a program or system can function together well. Acceptance testing focuses on the client's use of the system and how it functions as a whole unit, rather than on the specific interaction between different aspects.
May be something like this
config/routes.rb
namespace 'test_api' do
resource 'db_transaction', only: [:create, :destroy]
end if Rails.env.test?
controllers/test_api/db_transactions_controller.rb
require 'database_cleaner'
def create
DatabaseCleaner.start
end
def destroy
DatabaseCleaner.clean
end
