Feature Testing: Protecting Your Application

Feature tests send HTTP requests to your app and assert responses.

  ## Create test
  
  ```bash
  php artisan make:test PostTest
  ```
  
  ## Example test
  
  ```php
  public function test_posts_page_loads() {
    $response = $this->get('/posts');
    $response->assertStatus(200);
  }
  ```
  
  ## Authenticated test
  
  ```php
  $user = User::factory()->create();
  $this->actingAs($user)
    ->post('/posts', ['title' => 'Test', 'body' => 'Body text'])
    ->assertRedirect('/posts');
  ```
  
  ## Test flow
  
  ```mermaid

    A[Test] --> B[HTTP Request]
    B --> C[Laravel App]
    C --> D[Response]
    D --> A
  ```
  
  Tests help you refactor with confidence.
