What's going on here? So.. This is the task implementation for an interview, with requirement details located here. Before review, need to pay attention to the section below.
-
Horizontal Layer Implementation: Oh yes, we will not see classical vertical architecture style here. This architecture style is suitable only for apps, which will scale in functionality and complexity over time. In any case this example showcases how a module can be structured with a separation between the infra, logic, and presentation layers with clear dependency direction towards the domain layer. Each module is self-contained and can be easily removed due to transparent logical boundaries.
-
Expression Evaluation: I've decided to find the correct answer through evaluating expressions at runtime on the server side. Although, of course, it is better to store the correct answers in DB - less code, simpler and faster. But it will be boring for a test task.
The application has several routes that demonstrate the basic functionality:
GET /api/testing/questions: Fetches and randomizes the questions for the test.POST /api/testing/evaluate: Evaluates the submitted answers and returns the test results.GET /api/testing/results: Retrieves the test result stats.DELETE /api/testing/results: Clears all test result stats.
To get the application up and running, follow these steps:
- Clone the repository from GitHub.
- Make sure, that's port 8080 has not been used.
- Run
docker-compose up --build. - Run migrations
docker-compose exec testing_app php /var/www/bin/console doctrine:migrations:migrate --no-interaction - Open http://localhost:8080/.
