LARAVEL Professional Standards & Competencies 3

Question 1

What is the professional standard for writing Laravel feature tests that interact with the database?

Accepted Answer

Use the `RefreshDatabase` or `DatabaseTransactions` trait to reset state between tests

Answer

The `RefreshDatabase` trait runs migrations fresh per test suite and `DatabaseTransactions` wraps each test in a rolled-back transaction to ensure isolation.

Question 2

Which approach is the Laravel-recommended way to authorize actions in controllers?

Accepted Answer

Use Gate facades or Policy classes with `authorize()`

Answer

Laravel Policies and Gates provide a clean, centralized authorization layer called via `$this->authorize()` in controllers.

Question 3

What does it mean to follow the 'thin controller, fat model' principle in Laravel professionally?

Accepted Answer

Business logic resides in models/services, while controllers only handle HTTP input/output

Answer

Thin controllers delegate business logic to models or service classes, making controllers responsible only for receiving requests and returning responses.

Question 4

Which Laravel tool is the professional standard for managing database schema changes across a team?

Accepted Answer

Using Laravel Migrations with version-controlled migration files

Answer

Migrations provide version-controlled, team-shareable database schema changes that can be applied or rolled back consistently.

Question 5

What is the recommended Laravel practice for handling complex query logic that is reused across multiple controllers?

Accepted Answer

Define named scopes on the Eloquent model or use a Repository class

Answer

Eloquent local scopes encapsulate reusable query constraints on the model, while Repositories centralize more complex data-access patterns.
