What is a Factory in Laravel?
Why Interviewers Ask This
This is a classic screening question for Laravel roles. Hiring managers ask it early in interviews to gauge your baseline understanding and determine if you can communicate technical concepts clearly.
Answer
Model Factories generate fake model instances for testing and seeding. Generate: php artisan make:factory UserFactory --model=User. Factories use the Faker library to generate realistic fake data. Define state: public function definition(): array { return ["name" => $this->faker->name, "email" => $this->faker->email, "password" => bcrypt("password")]; }. Create instances: User::factory()->make() (not persisted), User::factory()->create() (saved to DB), User::factory()->count(10)->create() (bulk). Override specific attributes: User::factory()->create(["name" => "Alice"]). Define states for special conditions: User::factory()->admin()->create(). Factories are essential for feature tests and development data.
Pro Tip
If you're unsure about a detail, say so honestly and explain your reasoning. Interviewers respect candidates who can think through uncertainty rather than bluffing.
