Start built-in php server from php unit test

macrominds/website-testing allows you to start the built-in php server directly inside unit tests or other php scripts. Especially useful for functional testing. Helps to reduce external dependencies and to make your project self-contained.

Usage example

A rough usage overview. See below for a detailed example.

$this->testServer = new EmbeddedServerController(HOST,PORT,DOCROOT,'./tests/web/router.php');
$this->testServer->start();
//...
$this->testServer->stopAndWaitForConnectionLoss();

See this projects' phpunit.xml to learn how you can define HOST, PORT and DOCROOT for your own project.

Installing macrominds/website-testing

Recommended: Composer

The recommended installation way is through Composer.

Run the Composer command to add the latest stable version of macrominds/website-testing to your development dependencies:

composer require --dev macrominds/website-testing

or add it to the appropriate section of your composer.json:

    "require-dev": {
        "macrominds/website-testing": "^0.1.0",
    }

Without Composer

You may as well use macrominds/website-testing without Composer. Just fetch src/EmbeddedServerController.php and then in your php file

require_once('path-to-your/src/EmbeddedServerController.php');

There you go. Ready for the detailed example?

Detailed usage example

Testing the behavior of your web application. This example uses Guzzle as the HTTP client and phpunit. It requires the usage of Composer.

Your composer.json should contain this section:

    "require-dev": {
        "phpunit/phpunit": "^5.3",
        "macrominds/website-testing": "^0.1.0",
        "guzzlehttp/guzzle": "^6.2"
    }

Make sure to update composer:

composer update

use GuzzleHttp\Client;
use GuzzleHttp\RequestOptions;
use macrominds\website\testing\EmbeddedServerController;

class FunctionalPageTest extends \PHPUnit_Framework_TestCase{
    /**
     *
     * @var EmbeddedServerController 
     */
    private static $serverController;
    private static $client;

// setup server

    public static function setupBeforeClass()
    {
        //see phpunit.xml for configuration of PORT, DOCROOT, ROUTERSCRIPT
        self::$serverController = new EmbeddedServerController('0.0.0.0',PORT,DOCROOT,ROUTERSCRIPT);
        self::$serverController->start();
        $host = self::$serverController->getHost();
        $port = PORT;
        self::$client = new Client([
            'base_uri' => "http://$host:$port"
        ]);
    }
  
// tear down server
  
    public static function tearDownAfterClass()
    {
        if (self::$serverController !== null) {
            self::$serverController->stopAndWaitForConnectionLoss();
        }
        self::$serverController = null;
    }

// arbitrary tests

    /**
     * @test
     */
    public function shouldSendCorrectRedirectHeaders()
    {
        // we expect a temporary redirect
        $this->assertCorrectnessOfRedirectHeader(302);
        // we expect a permanent redirect
        $this->assertCorrectnessOfRedirectHeader(301);
    }
    
    private function assertCorrectnessOfRedirectHeader($code)
    {
        // our test scenario is setup to answer requests to /301.html 
        // or /302.html with the corresponding redirect.
        $response = self::$client->get("/$code.html", [
            RequestOptions::ALLOW_REDIRECTS=>false
        ]);
        $this->assertEquals($code, $response->getStatusCode());
    }
}

Troubleshooting

If you've got any issues or feature-requests, just add it to the Issues section.

Running the tests from your project root in the first place could help tracking down any issues related to your system.

bin/phpunit -c vendor/macrominds/website-testing/phpunit.xml

Have fun.
