Laravel dusk

Download The Code

​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. However, you are free to utilize any other Selenium driver you wish.

Quickstart (For Laravel 5.4)

Note: Dusk is not currently compatible with Windows. We need assistance from Windows users to provide the code to correctly start Chromedriver on Windows.

composer require laravel/dusk --dev

Once Dusk is installed, you need to register the Laravel\Dusk\DuskServiceProvider service provider. You should do this within the register method of your AppServiceProvider in order to limit the environments in which Dusk is available, since it exposes the ability to login as other users:

if ($this->app->environment('local', 'testing')) {
    $this->app->register(DuskServiceProvider::class);
}

Next, run the dusk:install Artisan command:

php artisan dusk:install

A Browser directory will be created within your tests directory containing an example test. Examples of advanced testing and page objects will be available with the full documentation.

To run your tests, use the dusk command. The dusk command accepts any argument that is also accepted by the phpunitcommand:

php artisan dusk

Environments

To force Dusk to use its own environment file, 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.

Multiple Browsers

If you would like to test a scenario that requires multiple browser windows, such as event broadcasting, simply "ask" for a second browser in your callback signature:

$this->browse(function ($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');
});

Waiting

Dusk allows you to easily wait for certain conditions to be true on your page. This is particularly useful for JavaScript heavy applications:

$this->browse(function ($browser) {
    $browser->loginAs(User::find(1))
            ->visit('/home')
            ->waitForText('Message');
            ->waitFor('css selector')
            ->waitFor('@pageObjectShortcut')
            ->waitUntil('javaScript.Expression')
            ->whenAvailable('#some-modal', function ($modal) {
                $modal->assertSee('Some Text');
            });
});

Page Objects / Selectors

Page objects allow you to define expressive actions that may be taken on a given page, as well as short-cuts for that page's selectors:

<?php

namespace Tests\Browser\Pages;

use Laravel\Dusk\Browser;

class Dashboard extends Page
{
    /**
     * Get the URL for the page.
     *
     * @return string
     */
    public function url()
    {
        return '/dashboard';
    }

    /**
     * Flush all of the todos.
     *
     * @return void
     */
    public function flushTodos(Browser $browser)
    {
        $browser->press('@deleteAll')->refresh();
    }

    /**
     * Get the element shortcuts for the page.
     *
     * @return array
     */
    public function elements()
    {
        return [
            '@deleteAll' => 'css > selector button[name=deleteAll]',
        ];
    }
}

Then, within your test you may navigate to and utilize the page:

$this->browse(function ($browser) {
    $browser->loginAs(User::find(1))
            ->visit(new Dashboard)
            ->flushTodos()
            ->assertVisible('@deleteAll');

});
