Laravel Development: How to use Laravel Dusk and Selenium for browser testing?

As web applications become more and more complex, we need to ensure that all parts of it function properly. Browser testing is a common testing method used to ensure the correctness and stability of an application under various browsers. In Laravel development, you can use Laravel Dusk and Selenium for browser testing. This article explains how to use these two tools for testing.

1. Basic concepts of Laravel Dusk

Laravel Dusk is Laravel’s official browser testing tool. It uses the Selenium WebDriver API to drive Chrome and Firefox browser-based tests and provides a concise and clear API. Using Laravel Dusk, you can easily write tests and automate the execution of multiple tests. Automating tests can improve test coverage while also reducing the time required for manual testing.

Install Laravel Dusk

Before starting testing, you must first install Laravel Dusk into the Laravel project. Laravel Dusk can be installed using Composer, using the following command:

composer require --dev laravel/dusk
Copy after login

Laravel Dusk requires a new database to store the data created during testing. This database can be configured in a .env test environment:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=dusk
DB_USERNAME=root
DB_PASSWORD=
Copy after login

After that, run the following commands to do some necessary installation of Dusk:

php artisan dusk:install
php artisan dusk:chrome-driver
Copy after login

Dusk is now installed and ready to be used in the project used.

2. Writing Laravel Dusk tests

Laravel Dusk allows you to define test cases in a fluent way. Test cases should be located in the tests/Browser directory. Each test case should inherit the DuskTestCase class and use the dusk method to launch the browser. Test cases can be generated using the following command:

php artisan dusk:make TestExample
Copy after login

This will create a test named TestExample in the tests/Browser directory.

Each test case should contain a test method, which defines the execution steps of the test case. In the test method, you can use the API provided by Laravel Dusk to simulate user behavior and assert the expected results of the test. For example:

$this->browse(function ($browser) {
    $browser->visit('/login')
            ->type('email', 'john@example.com')
            ->type('password', 'password')
            ->press('Login')
            ->assertPathIs('/home');
});
Copy after login

This test logs into the application and ensures that after login it redirects to the /home page. This test uses the visit method to access the /login page. Then, use the type method to populate the email and password fields and the press method to submit the form. Finally, use the assertPathIs method to assert whether the page URL is /home.

3. Selenium WebDriver configuration

Selenium WebDriver is an automated testing tool that supports various browsers. Dusk uses the Selenium API to handle browsers and perform tests. In order to use Selenium, the corresponding WebDriver binary needs to be downloaded. The WebDriver binary is the driver between the browser and Selenium. WebDriver binaries can be downloaded from:

Chrome: https://sites.google.com/a/chromium.org/chromedriver/downloads

Firefox: https://github. com/mozilla/geckodriver/releases

After downloading, place the WebDriver binary in the root directory of the Laravel project.

By default, Dusk uses Google Chrome as the browser. To use Firefox, you can set it in the .dusk.php configuration file:

'driver' => 'firefox'
Copy after login

4. Run the test using Dusk

After installing Laravel Dusk and writing test cases, you can use the following command to run the test :

php artisan dusk
Copy after login

This will launch Chrome and perform browser testing. After the test is completed, the test results can be viewed in the terminal window.

You can use the --group option to run a specific test group:

php artisan dusk --group=login
Copy after login

Browser testing with Laravel Dusk

Browser testing is important to ensure that the application runs accurately One of the methods. Use Laravel Dusk and Selenium WebDriver to write automated browser tests and verify the correctness and stability of your application. Using the method introduced in this article, you can write test cases to quickly perform browser testing.
