Published: June 2026 | Reading time: approx. 14 minutes Category: Quality assurance

Automated tests are an indispensable part of professional software development. They give you the assurance that your application works as expected, and allow you to make changes without having to be afraid to destroy something. Laravel offers an excellent testing infrastructure from home.

Types of tests in Laravel

Test type Description Location

**Unit tests * * Testing individual classes/methods isolated tests/unit/

**Feature tests * * Test all HTTP requests and answers tests/feature/

**Browser tests * * Test the application in real browser (Dusk) tests/Browser/

Run tests

Run all tests

php artisan test

♪ Unit tests only php artisan test --testsuite=Unit

♪ Only feature tests php artisan test --testsuite=Feature

♪ A specific test php artisan test --filter=UserTest

Your First Feature Test

php artisan make:test UserRegistrationTest

namespace Tests\Feature;

use Tests\TestCase; use Illuminate\Foundation\Testing\RefreshDatabase;

class UserRegistrationTest extends TestCase ♪ use RefreshDatabase;

public function test registration page can be rendered(): void ♪ $response = $this->get('/register');

$response>assertstatus(200); }

public function test new users can register(): void ♪ $response = $this->post('/register'), [ ‘name’ => ‘Test User’, ‘email’ => ‘test@example.com’, ‘password’ => ‘password’, 'password confirmation' => 'password', ),

$this->assertAuthenticated(); $response>assertRedirect('/dashboard'); } }

Database Testing with RefreshDatabase

The RefreshDatabase train resets the database after each test:

use Illuminate\Foundation\Testing\RefreshDatabase;

class PostTest extends TestCase ♪ use RefreshDatabase;

public function test posts can be created(): void ♪ $user = User:factory()->create();

$response = $this->actingAs($user)->post('/posts'), [ 'title' => 'My first contribution', 'content' => 'This is the content', ),

$this->assertDatabaseHas('posts'), [ 'title' => 'My first contribution', ), } }

Model Factories for Test Data

// database/factories/PostFactory.php class PostFactory extends factory ♪ public function definition(): array ♪ return ‘title’ => fake()->sentence(), ‘content’ => fake()->paragraph(3, true), 'user id' => User:factory(), ‘published’ => fake()->boolean(), ), }

public function published(): static ♪ return $this->state(fn (array $attributes) => [ ‘published’ => true, ), } }

// Use in tests $post = post:factory()->create(); Article 3

HTTP-Tests: Assertions

public function test api returns posts(): void ♪ Post::factory()->count(3)->create();

$response = $this->getJson('/api/posts'
