Laravel Dusk provides an expressive, easy-to-use browser automation and testing API. By default, Dusk does not require you to install JDK or Selenium on your local computer. Instead, Dusk uses a standalone ChromeDriver installation. However, you are free to utilize any other Selenium compatible driver you wish.
To get started, you should install Google Chrome and add the laravel/dusk
Composer dependency to your project:
composer require --dev laravel/dusk
Warning If you are manually registering Dusk's service provider, you should never register it in your production environment, as doing so could lead to arbitrary users being able to authenticate with your application.
After installing the Dusk package, execute the dusk:install
Artisan command. The dusk:install
command will create a tests/Browser
directory, an example Dusk test, and install the Chrome Driver binary for your operating system:
php artisan dusk:install
Next, set the APP_URL
environment variable in your application's .env
file. This value should match the URL you use to access your application in a browser.
Note If you are using Laravel Sail to manage your local development environment, please also consult the Sail documentation on configuring and running Dusk tests.
If you would like to install a different version of ChromeDriver than what is installed by Laravel Dusk via the dusk:install
command, you may use the dusk:chrome-driver
command:
# Install the latest version of ChromeDriver for your OS...
php artisan dusk:chrome-driver
# Install a given version of ChromeDriver for your OS...
php artisan dusk:chrome-driver 86
# Install a given version of ChromeDriver for all supported OSs...
php artisan dusk:chrome-driver --all
# Install the version of ChromeDriver that matches the detected version of Chrome / Chromium for your OS...
php artisan dusk:chrome-driver --detect
Warning Dusk requires the
chromedriver
binaries to be executable. If you're having problems running Dusk, you should ensure the binaries are executable using the following command:chmod -R 0755 vendor/laravel/dusk/bin/
.
By default, Dusk uses Google Chrome and a standalone ChromeDriver installation to run your browser tests. However, you may start your own Selenium server and run your tests against any browser you wish.
To get started, open your tests/DuskTestCase.php
file, which is the base Dusk test case for your application. Within this file, you can remove the call to the startChromeDriver
method. This will stop Dusk from automatically starting the ChromeDriver:
/**
* Prepare for Dusk test execution.
*
* @beforeClass
*/
public static function prepare(): void
{
// static::startChromeDriver();
}
Next, you may modify the driver
method to connect to the URL and port of your choice. In addition, you may modify the "desired capabilities" that should be passed to the WebDriver:
use Facebook\WebDriver\Remote\RemoteWebDriver;
/**
* Create the RemoteWebDriver instance.
*/
protected function driver(): RemoteWebDriver
{
return RemoteWebDriver::create(
'http://localhost:4444/wd/hub', DesiredCapabilities::phantomjs()
);
}
To generate a Dusk test, use the dusk:make
Artisan command. The generated test will be placed in the tests/Browser
directory:
php artisan dusk:make LoginTest
Most of the tests you write will interact with pages that retrieve data from your application's database; however, your Dusk tests should never use the RefreshDatabase
trait. The RefreshDatabase
trait leverages database transactions which will not be applicable or available across HTTP requests. Instead, you have two options: the DatabaseMigrations
trait and the DatabaseTruncation
trait.
The DatabaseMigrations
trait will run your database migrations before each test. However, dropping and re-creating your database tables for each test is typically slower than truncating the tables:
<?php
namespace Tests\Browser;
use App\Models\User;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Laravel\Dusk\Chrome;
use Tests\DuskTestCase;
class ExampleTest extends DuskTestCase
{
use DatabaseMigrations;
}
Warning SQLite in-memory databases may not be used when executing Dusk tests. Since the browser executes within its own process, it will not be able to access the in-memory databases of other processes.
Before using the DatabaseTruncation
trait, you must install the doctrine/dbal
package using the Composer package manager:
composer require --dev doctrine/dbal
The DatabaseTruncation
trait will migrate your database on the first test in order to ensure your database tables have been properly created. However, on subsequent tests, the database's tables will simply be truncated - providing a speed boost over re-running all of your database migrations:
<?php
namespace Tests\Browser;
use App\Models\User;
use Illuminate\Foundation\Testing\DatabaseTruncation;
use Laravel\Dusk\Chrome;
use Tests\DuskTestCase;
class ExampleTest extends DuskTestCase
{
use DatabaseTruncation;
}
By default, this trait will truncate all tables except the migrations
table. If you would like to customize the tables that should be truncated, you may define a $tablesToTruncate
property on your test class:
/**
* Indicates which tables should be truncated.
*
* @var array
*/
protected $tablesToTruncate = ['users'];
Alternatively, you may define an $exceptTables
property on your test class to specify which tables should be excluded from truncation:
/**
* Indicates which tables should be excluded from truncation.
*
* @var array
*/
protected $exceptTables = ['users'];
To specify the database connections that should have their tables truncated, you may define a $connectionsToTruncate
property on your test class:
/**
* Indicates which connections should have their tables truncated.
*
* @var array
*/
protected $connectionsToTruncate = ['mysql'];
To run your browser tests, execute the dusk
Artisan command:
php artisan dusk
If you had test failures the last time you ran the dusk
command, you may save time by re-running the failing tests first using the dusk:fails
command:
php artisan dusk:fails
The dusk
command accepts any argument that is normally accepted by the PHPUnit test runner, such as allowing you to only run the tests for a given group:
php artisan dusk --group=foo
Note If you are using Laravel Sail to manage your local development environment, please consult the Sail documentation on configuring and running Dusk tests.
By default, Dusk will automatically attempt to start ChromeDriver. If this does not work for your particular system, you may manually start ChromeDriver before running the dusk
command. If you choose to start ChromeDriver manually, you should comment out the following line of your tests/DuskTestCase.php
file:
/**
* Prepare for Dusk test execution.
*
* @beforeClass
*/
public static function prepare(): void
{
// static::startChromeDriver();
}
In addition, if you start ChromeDriver on a port other than 9515, you should modify the driver
method of the same class to reflect the correct port:
use Facebook\WebDriver\Remote\RemoteWebDriver;
/**
* Create the RemoteWebDriver instance.
*/
protected function driver(): RemoteWebDriver
{
return RemoteWebDriver::create(
'http://localhost:9515', DesiredCapabilities::chrome()
);
}
To force Dusk to use its own environment file when running tests, create a .env.dusk.{environment}
file in the root of your project. For example, if you will be initiating the dusk
command from your local
environment, you should create a .env.dusk.local
file.
When running tests, Dusk will back-up your .env
file and rename your Dusk environment to .env
. Once the tests have completed, your .env
file will be restored.
To get started, let's write a test that verifies we can log into our application. After generating a test, we can modify it to navigate to the login page, enter some credentials, and click the "Login" button. To create a browser instance, you may call the browse
method from within your Dusk test:
<?php
namespace Tests\Browser;
use App\Models\User;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Laravel\Dusk\Browser;
use Laravel\Dusk\Chrome;
use Tests\DuskTestCase;
class ExampleTest extends DuskTestCase
{
use DatabaseMigrations;
/**
* A basic browser test example.
*/
public function test_basic_example(): void
{
$user = User::factory()->create([
'email' => '[email protected]',
]);
$this->browse(function (Browser $browser) use ($user) {
$browser->visit('/login')
->type('email', $user->email)
->type('password', 'password')
->press('Login')
->assertPathIs('/home');
});
}
}
As you can see in the example above, the browse
method accepts a closure. A browser instance will automatically be passed to this closure by Dusk and is the main object used to interact with and make assertions against your application.
Sometimes you may need multiple browsers in order to properly carry out a test. For example, multiple browsers may be needed to test a chat screen that interacts with websockets. To create multiple browsers, simply add more browser arguments to the signature of the closure given to the browse
method:
$this->browse(function (Browser $first, Browser $second) {
$first->loginAs(User::find(1))
->visit('/home')
->waitForText('Message');
$second->loginAs(User::find(2))
->visit('/home')
->waitForText('Message')
->type('message', 'Hey Taylor')
->press('Send');
$first->waitForText('Hey Taylor')
->assertSee('Jeffrey Way');
});
The visit
method may be used to navigate to a given URI within your application:
$browser->visit('/login');
You may use the visitRoute
method to navigate to a named route:
$browser->visitRoute('login');
You may navigate "back" and "forward" using the back
and forward
methods:
$browser->back();
$browser->forward();
You may use the refresh
method to refresh the page:
$browser->refresh();
You may use the resize
method to adjust the size of the browser window:
$browser->resize(1920, 1080);
The maximize
method may be used to maximize the browser window:
$browser->maximize();
The fitContent
method will resize the browser window to match the size of its content:
$browser->fitContent();
When a test fails, Dusk will automatically resize the browser to fit the content prior to taking a screenshot. You may disable this feature by calling the disableFitOnFailure
method within your test:
$browser->disableFitOnFailure();
You may use the move
method to move the browser window to a different position on your screen:
$browser->move($x = 100, $y = 100);
If you would like to define a custom browser method that you can re-use in a variety of your tests, you may use the macro
method on the Browser
class. Typically, you should call this method from a service provider's boot
method:
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Laravel\Dusk\Browser;
class DuskServiceProvider extends ServiceProvider
{
/**
* Register Dusk's browser macros.
*/
public function boot(): void
{
Browser::macro('scrollToElement', function (string $element = null) {
$this->script("$('html, body').animate({ scrollTop: $('$element').offset().top }, 0);");
return $this;
});
}
}
The macro
function accepts a name as its first argument, and a closure as its second. The macro's closure will be executed when calling the macro as a method on a Browser
instance:
$this->browse(function (Browser $browser) use ($user) {
$browser->visit('/pay')
->scrollToElement('#credit-card-details')
->assertSee('Enter Credit Card Details');
});
Often, you will be testing pages that require authentication. You can use Dusk's loginAs
method in order to avoid interacting with your application's login screen during every test. The loginAs
method accepts a primary key associated with your authenticatable model or an authenticatable model instance:
use App\Models\User;
use Laravel\Dusk\Browser;
$this->browse(function (Browser $browser) {
$browser->loginAs(User::find(1))
->visit('/home');
});
Warning After using the
loginAs
method, the user session will be maintained for all tests within the file.
You may use the cookie
method to get or set an encrypted cookie's value. By default, all of the cookies created by Laravel are encrypted:
$browser->cookie('name');
$browser->cookie('name', 'Taylor');
You may use the plainCookie
method to get or set an unencrypted cookie's value:
$browser->plainCookie('name');
$browser->plainCookie('name', 'Taylor');
You may use the deleteCookie
method to delete the given cookie:
$browser->deleteCookie('name');
You may use the script
method to execute arbitrary JavaScript statements within the browser:
$browser->script('document.documentElement.scrollTop = 0');
$browser->script([
'document.body.scrollTop = 0',
'document.documentElement.scrollTop = 0',
]);
$output = $browser->script('return window.location.pathname');
You may use the screenshot
method to take a screenshot and store it with the given filename. All screenshots will be stored within the tests/Browser/screenshots
directory:
$browser->screenshot('filename');
The responsiveScreenshots
method may be used to take a series of screenshots at various breakpoints:
$browser->responsiveScreenshots('filename');
You may use the storeConsoleLog
method to write the current browser's console output to disk with the given filename. Console output will be stored within the tests/Browser/console
directory:
$browser->storeConsoleLog('filename');
You may use the storeSource
method to write the current page's source to disk with the given filename. The page source will be stored within the tests/Browser/source
directory:
$browser->storeSource('filename');
Choosing good CSS selectors for interacting with elements is one of the hardest parts of writing Dusk tests. Over time, frontend changes can cause CSS selectors like the following to break your tests:
// HTML...
<button>Login</button>
// Test...
$browser->click('.login-page .container div > button');
Dusk selectors allow you to focus on writing effective tests rather than remembering CSS selectors. To define a selector, add a dusk
attribute to your HTML element. Then, when interacting with a Dusk browser, prefix the selector with @
to manipulate the attached element within your test:
// HTML...
<button dusk="login-button">Login</button>
// Test...
$browser->click('@login-button');
Dusk provides several methods for interacting with the current value, display text, and attributes of elements on the page. For example, to get the "value" of an element that matches a given CSS or Dusk selector, use the value
method:
// Retrieve the value...
$value = $browser->value('selector');
// Set the value...
$browser->value('selector', 'value');
You may use the inputValue
method to get the "value" of an input element that has a given field name:
$value = $browser->inputValue('field');
The text
method may be used to retrieve the display text of an element that matches the given selector:
$text = $browser->text('selector');
Finally, the attribute
method may be used to retrieve the value of an attribute of an element matching the given selector:
$attribute = $browser->attribute('selector', 'value');
Dusk provides a variety of methods for interacting with forms and input elements. First, let's take a look at an example of typing text into an input field:
$browser->type('email', '[email protected]');
Note that, although the method accepts one if necessary, we are not required to pass a CSS selector into the type
method. If a CSS selector is not provided, Dusk will search for an input
or textarea
field with the given name
attribute.
To append text to a field without clearing its content, you may use the append
method:
$browser->type('tags', 'foo')
->append('tags', ', bar, baz');
You may clear the value of an input using the clear
method:
$browser->clear('email');
You can instruct Dusk to type slowly using the typeSlowly
method. By default, Dusk will pause for 100 milliseconds between key presses. To customize the amount of time between key presses, you may pass the appropriate number of milliseconds as the third argument to the method:
$browser->typeSlowly('mobile', '+1 (202) 555-5555');
$browser->typeSlowly('mobile', '+1 (202) 555-5555', 300);
You may use the appendSlowly
method to append text slowly:
$browser->type('tags', 'foo')
->appendSlowly('tags', ', bar, baz');
To select a value available on a select
element, you may use the select
method. Like the type
method, the select
method does not require a full CSS selector. When passing a value to the select
method, you should pass the underlying option value instead of the display text:
$browser->select('size', 'Large');
You may select a random option by omitting the second argument:
$browser->select('size');
By providing an array as the second argument to the select
method, you can instruct the method to select multiple options:
$browser->select('categories', ['Art', 'Music']);
To "check" a checkbox input, you may use the check
method. Like many other input related methods, a full CSS selector is not required. If a CSS selector match can't be found, Dusk will search for a checkbox with a matching name
attribute:
$browser->check('terms');
The uncheck
method may be used to "uncheck" a checkbox input:
$browser->uncheck('terms');
To "select" a radio
input option, you may use the radio
method. Like many other input related methods, a full CSS selector is not required. If a CSS selector match can't be found, Dusk will search for a radio
input with matching name
and value
attributes:
$browser->radio('size', 'large');
The attach
method may be used to attach a file to a file
input element. Like many other input related methods, a full CSS selector is not required. If a CSS selector match can't be found, Dusk will search for a file
input with a matching name
attribute:
$browser->attach('photo', __DIR__.'/photos/mountains.png');
Warning The attach function requires the
Zip
PHP extension to be installed and enabled on your server.
The press
method may be used to click a button element on the page. The argument given to the press
method may be either the display text of the button or a CSS / Dusk selector:
$browser->press('Login');
When submitting forms, many applications disable the form's submission button after it is pressed and then re-enable the button when the form submission's HTTP request is complete. To press a button and wait for the button to be re-enabled, you may use the pressAndWaitFor
method:
// Press the button and wait a maximum of 5 seconds for it to be enabled...
$browser->pressAndWaitFor('Save');
// Press the button and wait a maximum of 1 second for it to be enabled...
$browser->pressAndWaitFor('Save', 1);
To click a link, you may use the clickLink
method on the browser instance. The clickLink
method will click the link that has the given display text:
$browser->clickLink($linkText);
You may use the seeLink
method to determine if a link with the given display text is visible on the page:
if ($browser->seeLink($linkText)) {
// ...
}
Warning These methods interact with jQuery. If jQuery is not available on the page, Dusk will automatically inject it into the page so it is available for the test's duration.
The keys
method allows you to provide more complex input sequences to a given element than normally allowed by the type
method. For example, you may instruct Dusk to hold modifier keys while entering values. In this example, the shift
key will be held while taylor
is entered into the element matching the given selector. After taylor
is typed, swift
will be typed without any modifier keys:
$browser->keys('selector', ['{shift}', 'taylor'], 'swift');
Another valuable use case for the keys
method is sending a "keyboard shortcut" combination to the primary CSS selector for your application:
$browser->keys('.app', ['{command}', 'j']);
Note All modifier keys such as
{command}
are wrapped in{}
characters, and match the constants defined in theFacebook\WebDriver\WebDriverKeys
class, which can be found on GitHub.
The click
method may be used to click on an element matching the given CSS or Dusk selector:
$browser->click('.selector');
The clickAtXPath
method may be used to click on an element matching the given XPath expression:
$browser->clickAtXPath('//div[@class = "selector"]');
The clickAtPoint
method may be used to click on the topmost element at a given pair of coordinates relative to the viewable area of the browser:
$browser->clickAtPoint($x = 0, $y = 0);
The doubleClick
method may be used to simulate the double click of a mouse:
$browser->doubleClick();
The rightClick
method may be used to simulate the right click of a mouse:
$browser->rightClick();
$browser->rightClick('.selector');
The clickAndHold
method may be used to simulate a mouse button being clicked and held down. A subsequent call to the releaseMouse
method will undo this behavior and release the mouse button:
$browser->clickAndHold()
->pause(1000)
->releaseMouse();
The mouseover
method may be used when you need to move the mouse over an element matching the given CSS or Dusk selector:
$browser->mouseover('.selector');
The drag
method may be used to drag an element matching the given selector to another element:
$browser->drag('.from-selector', '.to-selector');
Or, you may drag an element in a single direction:
$browser->dragLeft('.selector', $pixels = 10);
$browser->dragRight('.selector', $pixels = 10);
$browser->dragUp('.selector', $pixels = 10);
$browser->dragDown('.selector', $pixels = 10);
Finally, you may drag an element by a given offset:
$browser->dragOffset('.selector', $x = 10, $y = 10);
Dusk provides various methods to interact with JavaScript Dialogs. For example, you may use the waitForDialog
method to wait for a JavaScript dialog to appear. This method accepts an optional argument indicating how many seconds to wait for the dialog to appear:
$browser->waitForDialog($seconds = null);
The assertDialogOpened
method may be used to assert that a dialog has been displayed and contains the given message:
$browser->assertDialogOpened('Dialog message');
If the JavaScript dialog contains a prompt, you may use the typeInDialog
method to type a value into the prompt:
$browser->typeInDialog('Hello World');
To close an open JavaScript dialog by clicking the "OK" button, you may invoke the acceptDialog
method:
$browser->acceptDialog();
To close an open JavaScript dialog by clicking the "Cancel" button, you may invoke the dismissDialog
method:
$browser->dismissDialog();
Sometimes you may wish to perform several operations while scoping all of the operations within a given selector. For example, you may wish to assert that some text exists only within a table and then click a button within that table. You may use the with
method to accomplish this. All operations performed within the closure given to the with
method will be scoped to the original selector:
$browser->with('.table', function (Browser $table) {
$table->assertSee('Hello World')
->clickLink('Delete');
});
You may occasionally need to execute assertions outside of the current scope. You may use the elsewhere
and elsewhereWhenAvailable
methods to accomplish this:
$browser->with('.table', function (Browser $table) {
// Current scope is `body .table`...
$browser->elsewhere('.page-title', function (Browser $title) {
// Current scope is `body .page-title`...
$title->assertSee('Hello World');
});
$browser->elsewhereWhenAvailable('.page-title', function (Browser $title) {
// Current scope is `body .page-title`...
$title->assertSee('Hello World');
});
});
When testing applications that use JavaScript extensively, it often becomes necessary to "wait" for certain elements or data to be available before proceeding with a test. Dusk makes this a cinch. Using a variety of methods, you may wait for elements to become visible on the page or even wait until a given JavaScript expression evaluates to true
.
If you just need to pause the test for a given number of milliseconds, use the pause
method:
$browser->pause(1000);
If you need to pause the test only if a given condition is true
, use the pauseIf
method:
$browser->pauseIf(App::environment('production'), 1000);
Likewise, if you need to pause the test unless a given condition is true
, you may use the pauseUnless
method:
$browser->pauseUnless(App::environment('testing'), 1000);
The waitFor
method may be used to pause the execution of the test until the element matching the given CSS or Dusk selector is displayed on the page. By default, this will pause the test for a maximum of five seconds before throwing an exception. If necessary, you may pass a custom timeout threshold as the second argument to the method:
// Wait a maximum of five seconds for the selector...
$browser->waitFor('.selector');
// Wait a maximum of one second for the selector...
$browser->waitFor('.selector', 1);
You may also wait until the element matching the given selector contains the given text:
// Wait a maximum of five seconds for the selector to contain the given text...
$browser->waitForTextIn('.selector', 'Hello World');
// Wait a maximum of one second for the selector to contain the given text...
$browser->waitForTextIn('.selector', 'Hello World', 1);
You may also wait until the element matching the given selector is missing from the page:
// Wait a maximum of five seconds until the selector is missing...
$browser->waitUntilMissing('.selector');
// Wait a maximum of one second until the selector is missing...
$browser->waitUntilMissing('.selector', 1);
Or, you may wait until the element matching the given selector is enabled or disabled:
// Wait a maximum of five seconds until the selector is enabled...
$browser->waitUntilEnabled('.selector');
// Wait a maximum of one second until the selector is enabled...
$browser->waitUntilEnabled('.selector', 1);
// Wait a maximum of five seconds until the selector is disabled...
$browser->waitUntilDisabled('.selector');
// Wait a maximum of one second until the selector is disabled...
$browser->waitUntilDisabled('.selector', 1);
Occasionally, you may wish to wait for an element to appear that matches a given selector and then interact with the element. For example, you may wish to wait until a modal window is available and then press the "OK" button within the modal. The whenAvailable
method may be used to accomplish this. All element operations performed within the given closure will be scoped to the original selector:
$browser->whenAvailable('.modal', function (Browser $modal) {
$modal->assertSee('Hello World')
->press('OK');
});
The waitForText
method may be used to wait until the given text is displayed on the page:
// Wait a maximum of five seconds for the text...
$browser->waitForText('Hello World');
// Wait a maximum of one second for the text...
$browser->waitForText('Hello World', 1);
You may use the waitUntilMissingText
method to wait until the displayed text has been removed from the page:
// Wait a maximum of five seconds for the text to be removed...
$browser->waitUntilMissingText('Hello World');
// Wait a maximum of one second for the text to be removed...
$browser->waitUntilMissingText('Hello World', 1);
The waitForLink
method may be used to wait until the given link text is displayed on the page:
// Wait a maximum of five seconds for the link...
$browser->waitForLink('Create');
// Wait a maximum of one second for the link...
$browser->waitForLink('Create', 1);
The waitForInput
method may be used to wait until the given input field is visible on the page:
// Wait a maximum of five seconds for the input...
$browser->waitForInput($field);
// Wait a maximum of one second for the input...
$browser->waitForInput($field, 1);
When making a path assertion such as $browser->assertPathIs('/home')
, the assertion can fail if window.location.pathname
is being updated asynchronously. You may use the waitForLocation
method to wait for the location to be a given value:
$browser->waitForLocation('/secret');
The waitForLocation
method can also be used to wait for the current window location to be a fully qualified URL:
$browser->waitForLocation('https://example.com/path');
You may also wait for a named route's location:
$browser->waitForRoute($routeName, $parameters);
If you need to wait for a page to reload after performing an action, use the waitForReload
method:
use Laravel\Dusk\Browser;
$browser->waitForReload(function (Browser $browser) {
$browser->press('Submit');
})
->assertSee('Success!');
Since the need to wait for the page to reload typically occurs after clicking a button, you may use the clickAndWaitForReload
method for convenience:
$browser->clickAndWaitForReload('.selector')
->assertSee('something');
Sometimes you may wish to pause the execution of a test until a given JavaScript expression evaluates to true
. You may easily accomplish this using the waitUntil
method. When passing an expression to this method, you do not need to include the return
keyword or an ending semi-colon:
// Wait a maximum of five seconds for the expression to be true...
$browser->waitUntil('App.data.servers.length > 0');
// Wait a maximum of one second for the expression to be true...
$browser->waitUntil('App.data.servers.length > 0', 1);
The waitUntilVue
and waitUntilVueIsNot
methods may be used to wait until a Vue component attribute has a given value:
// Wait until the component attribute contains the given value...
$browser->waitUntilVue('user.name', 'Taylor', '@user');
// Wait until the component attribute doesn't contain the given value...
$browser->waitUntilVueIsNot('user.name', null, '@user');
The waitForEvent
method can be used to pause the execution of a test until a JavaScript event occurs:
$browser->waitForEvent('load');
The event listener is attached to the current scope, which is the body
element by default. When using a scoped selector, the event listener will be attached to the matching element:
$browser->with('iframe', function (Browser $iframe) {
// Wait for the iframe's load event...
$iframe->waitForEvent('load');
});
You may also provide a selector as the second argument to the waitForEvent
method to attach the event listener to a specific element:
$browser->waitForEvent('load', '.selector');
You may also wait for events on the document
and window
objects:
// Wait until the document is scrolled...
$browser->waitForEvent('scroll', 'document');
// Wait a maximum of five seconds until the window is resized...
$browser->waitForEvent('resize', 'window', 5);
Many of the "wait" methods in Dusk rely on the underlying waitUsing
method. You may use this method directly to wait for a given closure to return true
. The waitUsing
method accepts the maximum number of seconds to wait, the interval at which the closure should be evaluated, the closure, and an optional failure message:
$browser->waitUsing(10, 1, function () use ($something) {
return $something->isReady();
}, "Something wasn't ready in time.");
Sometimes you may not be able to click on an element because it is outside of the viewable area of the browser. The scrollIntoView
method will scroll the browser window until the element at the given selector is within the view:
$browser->scrollIntoView('.selector')

Dusk even allows you to make assertions on the state of Vue component data. For example, imagine your application contains the following Vue component:
// HTML...
<profile dusk="profile-component"></profile>
// Component Definition...
Vue.component('profile', {
template: '<div>{{ user.name }}</div>',
data: function () {
return {
user: {
name: 'Taylor'
}
};
}
});
You may assert on the state of the Vue component like so:
/**
* A basic Vue test example.
*/
public function test_vue(): void
{
$this->browse(function (Browser $browser) {
$browser->visit('/')
->assertVue('user.name', 'Taylor', '@profile-component');
});
}
Assert that a given Vue component data property does not match the given value:
$browser->assertVueIsNot($property, $value, $componentSelector = null);
Assert that a given Vue component data property is an array and contains the given value:
$browser->assertVueContains($property, $value, $componentSelector = null);
Assert that a given Vue component data property is an array and does not contain the given value:
$browser->assertVueDoesNotContain($property, $value, $componentSelector = null);
Sometimes, tests require several complicated actions to be performed in sequence. This can make your tests harder to read and understand. Dusk Pages allow you to define expressive actions that may then be performed on a given page via a single method. Pages also allow you to define short-cuts to common selectors for your application or for a single page.
To generate a page object, execute the dusk:page
Artisan command. All page objects will be placed in your application's tests/Browser/Pages
directory:
php artisan dusk:page Login
By default, pages have three methods: url
, assert
, and elements
. We will discuss the url
and assert
methods now. The elements
method will be discussed in more detail below.
The url
method should return the path of the URL that represents the page. Dusk will use this URL when navigating to the page in the browser:
/**
* Get the URL for the page.
*/
public function url(): string
{
return '/login';
}
The assert
method may make any assertions necessary to verify that the browser is actually on the given page. It is not actually necessary to place anything within this method; however, you are free to make these assertions if you wish. These assertions will be run automatically when navigating to the page:
/**
* Assert that the browser is on the page.
*/
public function assert(Browser $browser): void
{
$browser->assertPathIs($this->url());
}
Once a page has been defined, you may navigate to it using the visit
method:
use Tests\Browser\Pages\Login;
$browser->visit(new Login);
Sometimes you may already be on a given page and need to "load" the page's selectors and methods into the current test context. This is common when pressing a button and being redirected to a given page without explicitly navigating to it. In this situation, you may use the on
method to load the page:
use Tests\Browser\Pages\CreatePlaylist;
$browser->visit('/dashboard')
->clickLink('Create Playlist')
->on(new CreatePlaylist)
->assertSee('@create');
The elements
method within page classes allows you to define quick, easy-to-remember shortcuts for any CSS selector on your page. For example, let's define a shortcut for the "email" input field of the application's login page:
/**
* Get the element shortcuts for the page.
*
* @return array<string, string>
*/
public function elements(): array
{
return [
'@email' => 'input[name=email]',
];
}
Once the shortcut has been defined, you may use the shorthand selector anywhere you would typically use a full CSS selector:
$browser->type('@email', '[email protected]');
After installing Dusk, a base Page
class will be placed in your tests/Browser/Pages
directory. This class contains a siteElements
method which may be used to define global shorthand selectors that should be available on every page throughout your application:
/**
* Get the global element shortcuts for the site.
*
* @return array<string, string>
*/
public static function siteElements(): array
{
return [
'@element' => '#selector',
];
}
In addition to the default methods defined on pages, you may define additional methods which may be used throughout your tests. For example, let's imagine we are building a music management application. A common action for one page of the application might be to create a playlist. Instead of re-writing the logic to create a playlist in each test, you may define a createPlaylist
method on a page class:
<?php
namespace Tests\Browser\Pages;
use Laravel\Dusk\Browser;
class Dashboard extends Page
{
// Other page methods...
/**
* Create a new playlist.
*/
public function createPlaylist(Browser $browser, string $name): void
{
$browser->type('name', $name)
->check('share')
->press('Create Playlist');
}
}
Once the method has been defined, you may use it within any test that utilizes the page. The browser instance will automatically be passed as the first argument to custom page methods:
use Tests\Browser\Pages\Dashboard;
$browser->visit(new Dashboard)
->createPlaylist('My Playlist')
->assertSee('My Playlist');
Components are similar to Dusk’s “page objects”, but are intended for pieces of UI and functionality that are re-used throughout your application, such as a navigation bar or notification window. As such, components are not bound to specific URLs.
To generate a component, execute the dusk:component
Artisan command. New components are placed in the tests/Browser/Components
directory:
php artisan dusk:component DatePicker
As shown above, a "date picker" is an example of a component that might exist throughout your application on a variety of pages. It can become cumbersome to manually write the browser automation logic to select a date in dozens of tests throughout your test suite. Instead, we can define a Dusk component to represent the date picker, allowing us to encapsulate that logic within the component:
<?php
namespace Tests\Browser\Components;
use Laravel\Dusk\Browser;
use Laravel\Dusk\Component as BaseComponent;
class DatePicker extends BaseComponent
{
/**
* Get the root selector for the component.
*/
public function selector(): string
{
return '.date-picker';
}
/**
* Assert that the browser page contains the component.
*/
public function assert(Browser $browser): void
{
$browser->assertVisible($this->selector());
}
/**
* Get the element shortcuts for the component.
*
* @return array<string, string>
*/
public function elements(): array
{
return [
'@date-field' => 'input.datepicker-input',
'@year-list' => 'div > div.datepicker-years',
'@month-list' => 'div > div.datepicker-months',
'@day-list' => 'div > div.datepicker-days',
];
}
/**
* Select the given date.
*/
public function selectDate(Browser $browser, int $year, int $month, int $day): void
{
$browser->click('@date-field')
->within('@year-list', function (Browser $browser) use ($year) {
$browser->click($year);
})
->within('@month-list', function (Browser $browser) use ($month) {
$browser->click($month);
})
->within('@day-list', function (Browser $browser) use ($day) {
$browser->click($day);
});
}
}
Once the component has been defined, we can easily select a date within the date picker from any test. And, if the logic necessary to select a date changes, we only need to update the component:
<?php
namespace Tests\Browser;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Laravel\Dusk\Browser;
use Tests\Browser\Components\DatePicker;
use Tests\DuskTestCase;
class ExampleTest extends DuskTestCase
{
/**
* A basic component test example.
*/
public function test_basic_example(): void
{
$this->browse(function (Browser $browser) {
$browser->visit('/')
->within(new DatePicker, function (Browser $browser) {
$browser->selectDate(2019, 1, 30);
})
->assertSee('January');
});
}
}
Warning Most Dusk continuous integration configurations expect your Laravel application to be served using the built-in PHP development server on port 8000. Therefore, before continuing, you should ensure that your continuous integration environment has an
APP_URL
environment variable value ofhttp://127.0.0.1:8000
.
To run Dusk tests on Heroku CI, add the following Google Chrome buildpack and scripts to your Heroku app.json
file:
{
"environments": {
"test": {
"buildpacks": [
{ "url": "heroku/php" },
{ "url": "https://github.com/heroku/heroku-buildpack-google-chrome" }
],
"scripts": {
"test-setup": "cp .env.testing .env",
"test": "nohup bash -c './vendor/laravel/dusk/bin/chromedriver-linux > /dev/null 2>&1 &' && nohup bash -c 'php artisan serve --no-reload > /dev/null 2>&1 &' && php artisan dusk"
}
}
}
}
To run your Dusk tests on Travis CI, use the following .travis.yml
configuration. Since Travis CI is not a graphical environment, we will need to take some extra steps in order to launch a Chrome browser. In addition, we will use php artisan serve
to launch PHP's built-in web server:
language: php
php:
- 7.3
addons:
chrome: stable
install:
- cp .env.testing .env
- travis_retry composer install --no-interaction --prefer-dist
- php artisan key:generate
- php artisan dusk:chrome-driver
before_script:
- google-chrome-stable --headless --disable-gpu --remote-debugging-port=9222 http://localhost &
- php artisan serve --no-reload &
script:
- php artisan dusk
If you are using GitHub Actions to run your Dusk tests, you may use the following configuration file as a starting point. Like TravisCI, we will use the php artisan serve
command to launch PHP's built-in web server:
name: CI
on: [push]
jobs:
dusk-php:
runs-on: ubuntu-latest
