Question

请帮我设置我的测试环境。我在Ubuntu上运行，安装了selenium web服务器（并且正在运行），并且运行PHPUnit我正在执行我的测试。最可能的是，我已经遇到了一些小错误，但我现在不知道如何修复它。

我的代码很简单

class WebTest extends PHPUnit_Extensions_Selenium2TestCase 
{
protected function setUp()

{
    $this->setBrowser('firefox');
    $this->setBrowserUrl('http://www.google.com/');
}

public function testTitle()
{
    $this->url('http://www.google.com/');
    $this->assertEquals('google', $this->title());
}

但是收到此错误

PHP致命错误：Class＆＃39; PHPUnit_Extensions_Selenium2TestCase＆＃39;在第4行的/home/jozef/vendor/phpunit/phpunit-selenium/WebTest.php中找不到

我安装了Selenium

你能帮我继续吗？谢谢:)）

Answer 1

以下是如何在phpUnit，MacOS，laravel 5.2，firefox上运行在Firefox上记录的Selenium IDE测试的说明。我还展示了如何设置截图（我还设置了Laravel以便在测试结束后对DB进行清理）：

在test-s目录中，创建selenium目录。并创建文件： SeleniumClearTestCase.php

class SeleniumClearTestCase extends MigrationToSelenium2 // Poniewaz testy seleniumIDE są zapisane w starym formacie (selenium 1) to urzywamy tej przejsciowki.
{
    protected $baseUrl = 'http://yourservice.dev';

    protected function setUp()
    {
        $screenshots_dir = __DIR__.'/screenshots';
        if (! file_exists($screenshots_dir)) {
            mkdir($screenshots_dir, 0777, true);
        }
        $this->listener = new PHPUnit_Extensions_Selenium2TestCase_ScreenshotListener($screenshots_dir);

        $this->setBrowser('firefox');
        $this->setBrowserUrl($this->baseUrl);
        $this->createApplication(); // bootstrap laravel app
    }

    public function onNotSuccessfulTest($e)
    {
        $this->listener->addError($this, $e, null);
        parent::onNotSuccessfulTest($e);
    }

    /**
     * Wykonaj screenshot w danym mommencie.
     * @return
     */
    public function screenshot()
    {
        $this->listener->addError($this, new Exception, null); // ta funkcja troche myli nazwą, ale wykona ona tylko screenshota nic ponadto
    }

    /**
     * Creates the application.
     *
     * @return \Illuminate\Foundation\Application
     */
    public function createApplication()
    {
        $app = require __DIR__.'/../../bootstrap/app.php';

        $app->make(Illuminate\Contracts\Console\Kernel::class)->bootstrap();

        return $app;
    }
}

下一个文件：MigrationToSelenium2.php（来自github，但我添加了一些moficiations）：

下一个文件：LaravelTestCase.php这是Illuminate \ Foundation \ Testing \ TestCase的精确副本，但它不扩展PHPUnit_Framework_TestCase，而是PHPUnit_Extensions_Selenium2TestCase类。

上一个文件：在测试目录中创建文件testrunner（这是一个bash脚本）：

seleniumIsRun=`ps | grep -w selenium.jar | grep -v grep | wc -l`
if (( $seleniumIsRun == 0 )); then    # run selenium server if it is not run already
    java -jar ./tests/selenium/selenium.jar &
    sleep 5s
fi
rm -r ./tests/selenium/screenshots
php artisan db:seed    # reset DB using laravel (my laravel seeders clean db at the begining)
vendor/bin/phpunit  # run php unit (in laravel it is in this direcotry)

下一步，下载最新的＆＃34; Selenium Standalone Server＆＃34;来自http://www.seleniumhq.org/download/并更改其名称并将其复制到tests / selenium / selenium.jar。

下一步，如果您在控制台中没有java命令，请从http://www.oracle.com/technetwork/java/javase/downloads/index.html安装newerst JDK

<强> LARAVEL

在composer.json更新部分（添加：phpunit / phpunit-selenium（github）和我们的新类）

"require-dev": {
    "fzaninotto/faker": "~1.4",
    "mockery/mockery": "0.9.*",
    "phpunit/phpunit": "~4.0",
    "symfony/css-selector": "2.8.*|3.0.*",
    "symfony/dom-crawler": "2.8.*|3.0.*",
    "phpunit/phpunit-selenium": "> 1.2"
},

"autoload-dev": {
    "classmap": [
        "tests/selenium/SeleniumClearTestCase.php",
        "tests/selenium/MigrationToSelenium2.php",
        "tests/selenium/LaravelTestCase.php",
        "tests/TestCase.php"
    ]
},

然后运行

composer update

和

composer dump-autoload

好了，现在我们有所有文件来设置selenium和phpunit。因此，让我们在firefox中使用插件Selenium IDE进行一些测试，我们还需要安装Selenium IDE：PHP Formatters＆＃39;用于保存测试的插件为phpunit。当我们记录测试时，我们检查它是否有效，我们将其保存为phpunit（我们还可以保存测试的原生html selenium格式.se - 来源我们的php测试，并且能够将来在selenium IDE中手动运行它在未来...） - 然后我们将其复制到文件夹测试/ selenium /测试。然后我们通过删除setUp部分来更改测试，并将扩展类更改为SeleniumClearTestCase。例如，我们可以创建如下测试：

<?php

class LoginTest extends SeleniumClearTestCase
{
    public function testAdminLogin()
    {
        self::adminLogin($this);
    }

    public function testLogout()
    {
        self::adminLogin($this);

        //START POINT: User zalogowany
        self::logout($this);
    }

    public static function adminLogin($t)
    {
        self::login($t, 'jan.kowalski@gmail.com', 'secret_password');
        $t->assertEquals('Jan Kowalski', $t->getText('css=span.hidden-xs'));
    }

    // @source LoginTest.se
    public static function login($t, $login, $pass)
    {
        $t->open('/');
        $t->click("xpath=(//a[contains(text(),'Panel')])[2]");
        $t->waitForPageToLoad('30000');
        $t->type('name=email', $login);
        $t->type('name=password', $pass);
        $t->click("//button[@type='submit']");
        $t->waitForPageToLoad('30000');        
    }

    // @source LogoutTest.se
    public static function logout($t)
    {
        $t->click('css=span.hidden-xs');
        $t->click('link=Wyloguj');
        $t->waitForPageToLoad('30000');
        $t->assertEquals('PANEL', $t->getText("xpath=(//a[contains(text(),'Panel')])[2]"));
    }
}

正如您所看到的，我将可以重复使用的部件放在单独的STATIC功能中。以下更多使用静态函数的复杂测试（也可以清理DB）：

<?php
use App\Models\Device;
use App\Models\User;

class DeviceRegistrationTest extends SeleniumClearTestCase
{
    public function testDeviceRegistration()
    {
      $email = 'paris@gmail.com';
      self::registerDeviceAndClient($this,'Paris','Hilton',$email,'verydifficultpassword');
      self::cleanRegisterDeviceAndClient($email);
    }

    // ------- STATIC elements

    public static function registerDeviceAndClient($t,$firstname, $lastname, $email, $pass) {
      LoginTest::adminLogin($t);

      // START POINT: User zalogowany jako ADMIN
      $t->click('link=Urządzenia');
      $t->click('link=Rejestracja');
      $t->waitForPageToLoad('30000');
      $registerurl = $t->getText('css=h4');
      $token = $t->getEval("storedVars['registerurl'].match(/[^\\/]+$/)", compact('registerurl'))[0];
      $t->screenshot();
                         // LOG OUT ADMIn
      LoginTest::logout($t);
                        // Otwórz link do urzadzenia
      $t->open($registerurl);
      $t->click('link=Rejestracja');
      $t->waitForPageToLoad('30000');
      $t->type('name=email', $email);
      $t->screenshot(); // take some photo =)
      $t->click('css=button.button-control');
      $t->waitForPageToLoad('30000');
      // Symuluj klikniecie w link aktywacyjny z emaila
      $t->open('http://yourdomain.dev/rejestracja/'.$token);
      $t->type('name=firstname', $firstname);
      $t->type('name=lastname', $lastname);
      $t->type('name=password', $pass);
      $t->type('name=password_confirmation', $pass);
      $t->screenshot(); // powinno byc widac formularz rejestracyjny nowego klienta
      $t->click("//button[@type='submit']");
      $t->waitForPageToLoad('30000');
      // Asercje
      $t->assertEquals($firstname.' '.$lastname, $t->getText('css=span.hidden-xs'));
    }

    public static function cleanRegisterDeviceAndClient($email) {
      $user = User::where('email','=',$email)->first();
      $device = Device::where('client_user_id','=',$user->id);
      $device->forceDelete();
      $user->forceDelete();
    }
}

你通过

进行测试

./ TestRunner的

Answer 2

你最近更新了你的phpunit吗？

最新版本的phpunit不再使用这个php绑定编译，只是遇到了同样的问题。

您可以使用phpunit-4.7.0版本进行测试吗？

/usr/bin/wget https://phar.phpunit.de/phpunit-4.7.0.phar -O /vagrant/tools/phpunit.phar && chmod +x /vagrant/tools/phpunit.phar && sudo mv /vagrant/tools/phpunit.phar /usr/local/bin/phpunit

搜索我的bash历史并粘贴在那里，只需更正您的环境路径。

上面的行应该更新你的phpunit for 4.7.0版本，这是一个使用PHPUnit_Extensions_Selenium2TestCase绑定编译phar的版本。

这应该可行，只要确保这个phpunit版本降级不会对你造成任何副作用。

使用PHPUnit和Selenium设置测试
