How to use PHP WebDriver for form testing and input testing

For PHP developers, testing is a very important step. In testing, form testing and input testing are extremely common test types. For both types of testing, PHP WebDriver is a very suitable testing tool. In this article, we will take a deep dive into how to use PHP WebDriver for form testing and input testing.

What is PHP WebDriver?

First, let us understand what PHP WebDriver is. PHP WebDriver is a PHP wrapper based on Selenium WebDriver. It can drive various browsers, including Firefox, Chrome, etc., to simulate user operations. PHP WebDriver can be used to perform various tests, including form testing and input testing.

Form Test

Form test is a common type of test, mainly used to test various forms in the website (such as registration form, login form, etc.). The following will introduce how to use PHP WebDriver for form testing.

1. Set up the environment

First, you need to install PHP WebDriver. PHP WebDriver can be installed through Composer. The specific steps are as follows:

(1) Create a composer.json file in the directory of the current project with the following content:

{

"require": {
    "php-webdriver/webdriver": "dev-master"
}

}

(2) Enter the directory where the composer.json file is located in the terminal, and then run the following command:

composer install

2. Create a test class

Next, you need to create a test class and write test code in this class. Test code can be written using PHPUnit. The following is a sample code:

use PHPUnitFrameworkTestCase;
use FacebookWebDriverRemoteRemoteWebDriver;
use FacebookWebDriverWebDriverBy;
use FacebookWebDriverWebDriverExpectedCondition;

class FormTest extends TestCase
{

/**
 * @var RemoteWebDriver
 */
protected $webDriver;

public function setUp()
{
    $capabilities = [
        'browserName' => 'chrome',
    ];

    $this->webDriver = RemoteWebDriver::create('http://localhost:4444/wd/hub', $capabilities);
    $this->webDriver->manage()->window()->maximize();
}

public function tearDown()
{
    $this->webDriver->quit();
}

public function testForm()
{
    $this->webDriver->get('http://localhost/form/');
    $this->webDriver->findElement(WebDriverBy::id('name'))->sendKeys('test');
    $this->webDriver->findElement(WebDriverBy::id('email'))->sendKeys('test@example.com');
    $this->webDriver->findElement(WebDriverBy::id('password'))->sendKeys('password');
    $this->webDriver->findElement(WebDriverBy::id('confirm_password'))->sendKeys('password');
    $this->webDriver->findElement(WebDriverBy::id('submit'))->click();

    $this->webDriver->wait(10)->until(
        WebDriverExpectedCondition::urlContains('success.php')
    );
}

}

In the above sample code, the Chrome browser is used and a form page is opened. Then, find each element of the form through the findElement method, enter the data and submit the form. Finally, wait for the jump to the success page through the wait method.

Input testing

Similar to form testing, input testing is also a common test type. Input testing refers to testing input boxes, drop-down list boxes, multi-select boxes, etc. in the website. Here's how to use PHP WebDriver for input testing.

1. Set up the environment

Similar to form testing, you first need to install PHP WebDriver. The installation steps are similar to the above and will not be repeated here.

2. Create a test class

Next, you need to create a test class and write test code in this class. The following is a sample code:

use PHPUnitFrameworkTestCase;
use FacebookWebDriverRemoteRemoteWebDriver;
use FacebookWebDriverWebDriverBy;
use FacebookWebDriverWebDriverExpectedCondition;

class InputTest extends TestCase
{

/**
 * @var RemoteWebDriver
 */
protected $webDriver;

public function setUp()
{
    $capabilities = [
        'browserName' => 'chrome',
    ];

    $this->webDriver = RemoteWebDriver::create('http://localhost:4444/wd/hub', $capabilities);
    $this->webDriver->manage()->window()->maximize();
}

public function tearDown()
{
    $this->webDriver->quit();
}

public function testInput()
{
    $this->webDriver->get('http://localhost/input/');
    $this->webDriver->findElement(WebDriverBy::id('input'))->sendKeys('test');
    $this->webDriver->findElement(WebDriverBy::id('select'))->click();
    $this->webDriver->findElement(WebDriverBy::xpath('//option[text()="option1"]'))->click();
    $this->webDriver->findElement(WebDriverBy::id('checkbox1'))->click();
    $this->webDriver->findElement(WebDriverBy::id('radio1'))->click();
}

}

In the above sample code, the Chrome browser is used and an input test page is opened. Then, find the input box, drop-down list box, multi-select box and radio button box through the findElement method, and operate them.

Summary

Through the introduction of this article, we have learned how to use PHP WebDriver for form testing and input testing. PHP WebDriver is a very convenient testing tool that can greatly reduce testing time and improve testing efficiency. Whether for beginners or experienced developers, PHP WebDriver is a testing tool worth trying.
