Laravel Dusk Skill

Comprehensive assistance with Laravel Dusk browser automation and testing, providing expert guidance on writing expressive, easy-to-use browser tests for your Laravel applications.

When to Use This Skill

This skill should be triggered when:

• Writing or debugging browser automation tests for Laravel
• Testing user interfaces and JavaScript interactions
• Implementing end-to-end (E2E) testing workflows
• Setting up automated UI testing in Laravel applications
• Working with form submissions, authentication flows, or page navigation tests
• Configuring ChromeDriver or alternative browser drivers
• Using the Page Object pattern for test organization
• Testing Vue.js components or waiting for JavaScript events
• Troubleshooting browser test failures or timing issues

Quick Reference

1. Basic Browser Test

public function testBasicExample(): void
{
    $this->browse(function (Browser $browser) {
        $browser->visit('/login')
            ->type('email', 'user@example.com')
            ->type('password', 'password')
            ->press('Login')
            ->assertPathIs('/home');
    });
}

2. Using Dusk Selectors (Recommended)

<!-- In your Blade template -->
<button dusk="login-button">Login</button>
<input dusk="email-input" name="email" />

// In your test - use @ prefix for dusk selectors
$browser->type('@email-input', 'user@example.com')
    ->click('@login-button');

3. Testing Multiple Browsers

public function testMultiUserInteraction(): void
{
    $this->browse(function (Browser $first, Browser $second) {
        $first->loginAs(User::find(1))
            ->visit('/home');

        $second->loginAs(User::find(2))
            ->visit('/home');
    });
}

4. Waiting for Elements

// Wait for element to appear
$browser->waitFor('.modal')
    ->assertSee('Confirmation Required');

// Wait for text to appear
$browser->waitForText('Hello World');

// Wait for JavaScript condition
$browser->waitUntil('App.data.servers.length > 0');

// Wait when element is available
$browser->whenAvailable('.modal', function (Browser $modal) {
    $modal->assertSee('Delete Account')
        ->press('OK');
});

5. Form Interactions

// Text input
$browser->type('email', 'user@example.com')
    ->append('notes', 'Additional text')
    ->clear('description');

// Dropdown selection
$browser->select('size', 'Large')
    ->select('categories', ['Art', 'Music']); // Multiple

// Checkboxes and radio buttons
$browser->check('terms')
    ->radio('gender', 'male');

// File upload
$browser->attach('photo', __DIR__.'/photos/profile.jpg');

6. Page Object Pattern

// Generate page object
// php artisan dusk:page Login

// app/tests/Browser/Pages/Login.php
class Login extends Page
{
    public function url(): string
    {
        return '/login';
    }

    public function elements(): array
    {
        return [
            '@email' => 'input[name=email]',
            '@password' => 'input[name=password]',
            '@submit' => 'button[type=submit]',
        ];
    }

    public function login(Browser $browser, $email, $password): void
    {
        $browser->type('@email', $email)
            ->type('@password', $password)
            ->press('@submit');
    }
}

// Use in test
$browser->visit(new Login)
    ->login('user@example.com', 'password')
    ->assertPathIs('/dashboard');

7. Browser Macros (Reusable Methods)

// In AppServiceProvider or DuskServiceProvider
use Laravel\Dusk\Browser;

Browser::macro('scrollToElement', function (string $element) {
    $this->script("$('html, body').animate({
        scrollTop: $('{$element}').offset().top
    }, 0);");

    return $this;
});

// Use in tests
$browser->scrollToElement('#footer')
    ->assertSee('Copyright 2024');

8. Database Management in Tests

use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\DatabaseTruncation;

class ExampleTest extends DuskTestCase
{
    // Option 1: Run migrations before each test (slower)
    use DatabaseMigrations;

    // Option 2: Truncate tables after first migration (faster)
    use DatabaseTruncation;

    // Exclude specific tables from truncation
    protected $exceptTables = ['migrations'];
}

9. JavaScript Execution

// Execute JavaScript
$browser->script('document.documentElement.scrollTop = 0');

// Get JavaScript return value
$path = $browser->script('return window.location.pathname');

// Wait for reload after action
$browser->waitForReload(function (Browser $browser) {
    $browser->press('Submit');
})->assertSee('Success');

10. Common Assertions

// Page assertions
$browser->assertPathIs('/dashboard')
    ->assertRouteIs('dashboard')
    ->assertTitle('Dashboard')
    ->assertSee('Welcome Back')
    ->assertDontSee('Error');

// Form assertions
$browser->assertInputValue('email', 'user@example.com')
    ->assertChecked('remember')
    ->assertSelected('role', 'admin')
    ->assertEnabled('submit-button');

// Element assertions
$browser->assertVisible('.success-message')
    ->assertMissing('.error-alert')
    ->assertPresent('button[type=submit]');

// Authentication assertions
$browser->assertAuthenticated()
    ->assertAuthenticatedAs($user);

Key Concepts

Dusk Selectors vs CSS Selectors

Dusk selectors (recommended) use HTML

dusk

attributes that won't change with UI updates:

• More stable than CSS classes or IDs
• Explicitly mark elements for testing
• Use

  @

  prefix in tests:

  $browser->click('@submit-button')

• Add to HTML:

  <button dusk="submit-button">Submit</button>

CSS selectors are more brittle but sometimes necessary:

• .class-name

  ,

  #id

  ,

  div > button

• Can break when HTML structure changes
• Use when you don't control the HTML

Waiting Strategies

Always wait explicitly rather than using arbitrary pauses:

• waitFor('.selector')

  - Wait for element to exist

• waitUntilMissing('.selector')

  - Wait for element to disappear

• waitForText('text')

  - Wait for text to appear

• waitUntil('condition')

  - Wait for JavaScript condition

• whenAvailable('.selector', callback)

  - Run callback when available

Page Objects

Organize complex test logic into Page classes:

• Define URL, assertions, and element selectors
• Create reusable methods for page-specific actions
• Improve test readability and maintainability
• Generate with:

  php artisan dusk:page PageName

Browser Macros

Define reusable browser methods for common patterns:

• Register in service provider's

  boot()

  method
• Use across all tests
• Chain like built-in methods
• Example: scrolling, modal interactions, custom assertions

Working with This Skill

For Beginners

1. Start with basic tests: Use simple

   visit()

   ,

   type()

   ,

   press()

   , and

   assertSee()

   methods
2. Use Dusk selectors: Add

   dusk

   attributes to your HTML for stable selectors
3. Learn waiting: Always use

   waitFor()

   instead of

   pause()

   for reliable tests
4. Run tests: Execute with

   php artisan dusk

   to see results

For Intermediate Users

1. Implement Page Objects: Organize complex tests with the Page pattern
2. Use database traits: Choose between

   DatabaseMigrations

   or

   DatabaseTruncation

3. Create browser macros: Define reusable methods for common workflows
4. Test authentication: Use

   loginAs()

   to bypass login screens
5. Handle JavaScript: Use

   waitUntil()

   for dynamic content and AJAX

For Advanced Users

1. Multi-browser testing: Test real-time features with multiple browsers
2. Custom waiting logic: Use

   waitUsing()

   for complex conditions
3. Component pattern: Create reusable components for shared UI elements
4. CI/CD integration: Set up Dusk in GitHub Actions, Travis CI, or other platforms
5. Alternative drivers: Configure Selenium Grid or other browsers beyond ChromeDriver

Best Practices

1. Use Dusk selectors (

   dusk

   attributes) instead of CSS classes for stability
2. Wait explicitly with

   waitFor()

   methods instead of arbitrary

   pause()

3. Organize with Page Objects for complex test scenarios
4. Leverage database truncation for faster test execution
5. Create browser macros for frequently repeated actions
6. Scope selectors with

   with()

   or

   elsewhere()

   for specific page regions
7. Test user behavior rather than implementation details
8. Use authentication shortcuts like

   loginAs()

   to skip login flows
9. Take screenshots with

   screenshot()

   for debugging failures
10. Group related tests and use

    --group

    flag for targeted execution

Troubleshooting

Common Issues

ChromeDriver version mismatch:

php artisan dusk:chrome-driver --detect

Elements not found:

• Use

  waitFor('.selector')

  before interacting
• Check if element is in an iframe
• Verify selector with browser dev tools

Tests failing randomly:

• Replace

  pause()

  with explicit waits
• Increase timeout:

  waitFor('.selector', 10)

• Use

  waitUntil()

  for JavaScript conditions

Database state issues:

• Use

  DatabaseTruncation

  trait
• Reset data in

  setUp()

  method
• Check for transactions in application code

Notes

• Laravel Dusk uses ChromeDriver by default (no Selenium/JDK required)
• Supports alternative browsers via Selenium WebDriver protocol
• Tests are stored in

  tests/Browser

  directory
• Page objects go in

  tests/Browser/Pages

• Screenshots saved to

  tests/Browser/screenshots

  on failure
• Console logs saved to

  tests/Browser/console

  for debugging
