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 machine. 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 add the laravel/dusk Composer dependency to your project:
composer require --dev laravel/dusk
{note} 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, run the dusk:install Artisan command:
php artisan dusk:install
A Browser directory will be created within your tests directory and will contain an example test. Next, set the APP_URL environment variable in your .env file. This value should match the URL you use to access your application in a browser.
To run your tests, use the dusk Artisan command. The dusk command accepts any argument that is also accepted by the phpunit 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
If you would like to install a different version of ChromeDriver than what is included with Laravel Dusk, 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 74
# Install a given version of ChromeDriver for all supported OSs...
php artisan dusk:chrome-driver --all
{note} Dusk requires the
chromedriverbinaries 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
* @return void
*/
public static function prepare()
{
// 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:
/**
* Create the RemoteWebDriver instance.
*
* @return \Facebook\WebDriver\Remote\RemoteWebDriver
*/
protected function driver()
{
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
To run your browser tests, use 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, allowing you to only run the tests for a given group, etc:
php artisan dusk --group=foo
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
* @return void
*/
public static function prepare()
{
// static::startChromeDriver();
}
In addition, if you start ChromeDriver on a port other than 9515, you should modify the driver method of the same class:
/**
* Create the RemoteWebDriver instance.
*
* @return \Facebook\WebDriver\Remote\RemoteWebDriver
*/
protected function driver()
{
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, call the browse method:
<?php
namespace Tests\Browser;
use App\User;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Laravel\Dusk\Chrome;
use Tests\DuskTestCase;
class ExampleTest extends DuskTestCase
{
use DatabaseMigrations;
/**
* A basic browser test example.
*
* @return void
*/
public function testBasicExample()
{
$user = factory(User::class)->create([
'email' => '[email protected]',
]);
$this->browse(function ($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 callback. A browser instance will automatically be passed to this callback 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, "ask" for more than one browser in the signature of the callback given to the browse method:
$this->browse(function ($first, $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');
});
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:
$browser->maximize();
If you would like to define a custom browser method that you can re-use in a variety of your tests, you may use the macro method on the Browser class. Typically, you should call this method from a service provider's boot method:
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Laravel\Dusk\Browser;
class DuskServiceProvider extends ServiceProvider
{
/**
* Register the Dusk's browser macros.
*
* @return void
*/
public function boot()
{
Browser::macro('scrollToElement', function ($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 implementation:
$this->browse(function ($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 the login screen during every test. The loginAs method accepts a user ID or user model instance:
$this->browse(function ($first, $second) {
$first->loginAs(User::find(1))
->visit('/home');
});
{note} After using the
loginAsmethod, the user session will be maintained for all tests within the file.
When your test requires migrations, like the authentication example above, you should never use the RefreshDatabase trait. The RefreshDatabase trait leverages database transactions which will not be applicable across HTTP requests. Instead, use the DatabaseMigrations trait:
<?php
namespace Tests\Browser;
use App\User;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Laravel\Dusk\Chrome;
use Tests\DuskTestCase;
class ExampleTest extends DuskTestCase
{
use DatabaseMigrations;
}
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, prefix the selector with @ to manipulate the attached element within a Dusk test:
// HTML...
<button dusk="login-button">Login</button>
// Test...
$browser->click('@login-button');
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);
{note} This method interacts 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.
Dusk provides several methods for interacting with the current display text, value, and attributes of elements on the page. For example, to get the "value" of an element that matches a given selector, use the value method:
// Retrieve the value...
$value = $browser->value('selector');
// Set the value...
$browser->value('selector', 'value');
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 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 field with the given name attribute. Finally, Dusk will attempt to find a textarea 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');
To select a value in a dropdown selection box, 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 parameter:
$browser->select('size');
To "check" a checkbox field, you may use the check method. Like many other input related methods, a full CSS selector is not required. If an exact selector match can't be found, Dusk will search for a checkbox with a matching name attribute:
$browser->check('terms');
$browser->uncheck('terms');
To "select" a radio button option, you may use the radio method. Like many other input related methods, a full CSS selector is not required. If an exact selector match can't be found, Dusk will search for a radio with matching name and value attributes:
$browser->radio('version', 'php7');
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 an exact selector match can't be found, Dusk will search for a file input with matching name attribute:
$browser->attach('photo', __DIR__.'/photos/me.png');
{note} The attach function requires the
ZipPHP extension to be installed and enabled on your server.
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 hold modifier keys 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, otwell will be typed without any modifier keys:
$browser->keys('selector', ['{shift}', 'taylor'], 'otwell');
You may even send a "hot key" to the primary CSS selector that contains your application:
$browser->keys('.app', ['{command}', 'j']);
{tip} All modifier keys are wrapped in
{}characters, and match the constants defined in theFacebook\WebDriver\WebDriverKeysclass, which can be found on GitHub.
The click method may be used to "click" on an element matching the given selector:
$browser->click('.selector');
The mouseover method may be used when you need to move the mouse over an element matching the given 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', 10);
$browser->dragRight('.selector', 10);
$browser->dragUp('.selector', 10);
$browser->dragDown('.selector', 10);
Dusk provides various methods to interact with JavaScript Dialogs:
// Wait for a dialog to appear:
$browser->waitForDialog($seconds = null);
// Assert that a dialog has been displayed and that its message matches the given value:
$browser->assertDialogOpened('value');
// Type the given value in an open JavaScript prompt dialog:
$browser->typeInDialog('Hello World');
To close an opened JavaScript Dialog, clicking the OK button:
$browser->acceptDialog();
To close an opened JavaScript Dialog, clicking the Cancel button (for a confirmation dialog only):
$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 callback given to the with method will be scoped to the original selector:
$browser->with('.table', function ($table) {
$table->assertSee('Hello World')
->clickLink('Delete');
});
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 be visible on the page or even wait until a given JavaScript expression evaluates to true.
If you need to pause the test for a given number of milliseconds, use the pause method:
$browser->pause(1000);
The waitFor method may be used to pause the execution of the test until the element matching the given CSS 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 given selector is missing from the page:
$browser->waitUntilMissing('.selector');
$browser->waitUntilMissing('.selector', 1);
Occasionally, you may wish to wait for a given selector and then interact with the element matching the selector. 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 in this case. All element operations performed within the given callback will be scoped to the original selector:
$browser->whenAvailable('.modal', function ($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);
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);
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');
You may also wait for a named route's location:
$browser->waitForRoute($routeName, $parameters);
If you need to make assertions after a page has been reloaded, use the waitForReload method:
$browser->click('.some-action')
->waitForReload()
->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.dataLoaded');
$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 following methods may be used to wait until a given 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');
Many of the "wait" methods in Dusk rely on the underlying waitUsing method. You may use this method directly to wait for a given callback 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.");
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.
*
* @return void
*/
public function testVue()
{
$this->browse(function (Browser $browser) {
$browser->visit('/')
->assertVue('user.name', 'Taylor', '@profile-component');
});
}
Dusk provides a variety of assertions that you may make against your application. All of the available assertions are documented in the list below:
<style> .collection-method-list > p { column-count: 3; -moz-column-count: 3; -webkit-column-count: 3; column-gap: 2em; -moz-column-gap: 2em; -webkit-column-gap: 2em; } .collection-method-list a { display: block; } </style>Assert that the page title matches the given text:

Sometimes, tests require several complicated actions to be performed in sequence. This can make your tests harder to read and understand. Pages allow you to define expressive actions that may then be performed on a given page using a single method. Pages also allow you to define short-cuts to common selectors for your application or a single page.
To generate a page object, use the dusk:page Artisan command. All page objects will be placed in the 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.
*
* @return string
*/
public function url()
{
return '/login';
}
The assert method may make any assertions necessary to verify that the browser is actually on the given page. Completing this method is not necessary; 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.
*
* @return void
*/
public function assert(Browser $browser)
{
$browser->assertPathIs($this->url());
}
Once a page has been configured, 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 of pages 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
*/
public function elements()
{
return [
'@email' => 'input[name=email]',
];
}
Now, you may use this shorthand selector anywhere you would 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
*/
public static function siteElements()
{
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.
*
* @param \Laravel\Dusk\Browser $browser
* @param string $name
* @return void
*/
public function createPlaylist(Browser $browser, $name)
{
$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 to the page method:
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, use the dusk:component Artisan command. New components are placed in the test/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.
*
* @return string
*/
public function selector()
{
return '.date-picker';
}
/**
* Assert that the browser page contains the component.
*
* @param Browser $browser
* @return void
*/
public function assert(Browser $browser)
{
$browser->assertVisible($this->selector());
}
/**
* Get the element shortcuts for the component.
*
* @return array
*/
public function elements()
{
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.
*
* @param \Laravel\Dusk\Browser $browser
* @param int $year
* @param int $month
* @param int $day
* @return void
*/
public function selectDate($browser, $year, $month, $day)
{
$browser->click('@date-field')
->within('@year-list', function ($browser) use ($year) {
$browser->click($year);
});
->within('@month-list', function ($browser) use ($month) {
$browser->click($month);
})
->within('@day-list', function ($browser) use ($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.
*
* @return void
*/
public function testBasicExample()
{
$this->browse(function (Browser $browser) {
$browser->visit('/')
->within(new DatePicker, function ($browser) {
$browser->selectDate(2019, 1, 30);
})
->assertSee('January');
});
}
}
If you are using CircleCI to run your Dusk tests, you may use this configuration file as a starting point. Like TravisCI, we will use the php artisan serve command to launch PHP's built-in web server:
version: 2
jobs:
build:
steps:
- run: sudo apt-get install -y libsqlite3-dev
- run: cp .env.testing .env
- run: composer install -n --ignore-platform-reqs
- run: npm install
- run: npm run production
- run: vendor/bin/phpunit
- run:
name: Start Chrome Driver
command: ./vendor/laravel/dusk/bin/chromedriver-linux
background: true
- run:
name: Run Laravel Server
command: php artisan serve
background: true
- run:
name: Run Laravel Dusk Tests
command: php artisan dusk
- store_artifacts:
path: tests/Browser/screenshots
To run Dusk tests on Codeship, add the following commands to your Codeship project. These commands are just a starting point and you are free to add additional commands as needed:
phpenv local 7.2
cp .env.testing .env
mkdir -p ./bootstrap/cache
composer install --no-interaction --prefer-dist
php artisan key:generate
nohup bash -c "php artisan serve 2>&1 &" && sleep 5
php artisan dusk
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 > /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 --no-suggest
- php artisan key:generate
before_script:
- google-chrome-stable --headless --disable-gpu --remote-debugging-port=9222 http://localhost &
- php artisan serve &
script:
- php artisan dusk
If you are using Github Actions to run your Dusk tests, you may use this 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
steps:
- uses: actions/checkout@v1
- name: Prepare The Environment
run: cp .env.example .env
- name: Create Database
run: mysql --user="root" --password="root" -e "CREATE DATABASE my-database character set UTF8mb4 collate utf8mb4_bin;"
- name: Install Composer Dependencies
run: composer install --no-progress --no-suggest --prefer-dist --optimize-autoloader
- name: Generate Application Key
run: php artisan key:generate
- name: Upgrade Chrome Driver
run: php artisan dusk:chrome-driver
- name: Start Chrome Driver
run: ./vendor/laravel/dusk/bin/chromedriver-linux > /dev/null 2>&1 &
- name: Run Laravel Server
run: php artisan serve > /dev/null 2>&1 &
- name: Run Dusk Tests
run: php artisan dusk
In your .env.testing file, adjust the value of APP_URL:
APP_URL=http://127.0.0.1:8000
