README

Provides an HTTP server test case for PHPUnit. The server is powered by PHP's built-in server for testing of network related calls.

Installing

This library requires PHP 7.3 or newer, including PHP 8.0, 8,1, and 8.2. It will run with PHPUnit versions 8 and 9.

composer require giberti/phpunit-local-server

Usage

Create a directory that will contain the code you want to execute
Extend the \Giberti\PHPUnitLocalServer\LocalServerTestCase as if you were extending \PHPUnit\Framework\TestCase
Start a server in the test method or for the entire class
Make requests against the server

Usage Tips

Whenever possible, re-use the existing server. Frequent restarts will slow down your tests.
You can provide a different php binary by overriding the static $phpBinary property on the class.

A single test

Call either the createServerWithDocroot() or createServerWithRouter() helper method and then execute your test.

use Giberti\PHPUnitLocalServer\LocalServerTestCase;

class Test extends LocalServerTestCase
{
    public function testFoo() {
        static::createServerWithDocroot('./tests/localhost');
        $url = $this->getLocalServerUrl() . '/foo';

        $content = file_get_contents($url);

        $this->assertEquals('...', $content, 'Content mismatch');
    }
}

Several tests using the same configuration

To optimize performance of your tests, it's best to re-use the server whenever possible. To make this easier, simply start the server at the beginning of the class by defining a setupBeforeClass() method with your desired configuration.

use Giberti\PHPUnitLocalServer\LocalServerTestCase;

class Test extends LocalServerTestCase
{
    public static function setupBeforeClass() {
        static::createServerWithDocroot('./tests/localhost');
    }

    public function testFoo() {
        $url = $this->getLocalServer() . '/foo';
        $content = file_get_contents($url);

        $this->assertEquals('...', $content, 'Content mismatch');
    }

    public function testBar() {
        $url = $this->getLocalServer() . '/bar';
        $content = file_get_contents($url);

        $this->assertEquals('...', $content, 'Content mismatch');
    }
}

Modifying the server runtime version

It's possible to run the server under a different PHP runtime than the version running your test suite. This can help with testing your code under multiple versions of PHP. In the example below, the server will start with the PHP 7.3 and 8.1 executable in /usr/local/bin/ on the host test system. Your path may be different.

use Giberti\PHPUnitLocalServer\LocalServerTestCase;

class Test73 extends LocalServerTestCase
{
    static $phpBinary = '/usr/local/bin/php73';

    public function testFoo() {
        static::createServerWithDocroot('./tests/localhost');

        $url = $this->getLocalServer() . '/foo';
        $content = file_get_contents($url);

        $this->assertEquals('...', $content, 'Content mismatch');
    }
}

class Test81 extends LocalServerTestCase
{
    static $phpBinary = '/usr/local/bin/php81';

    public function testFoo() {
        static::createServerWithDocroot('./tests/localhost');

        $url = $this->getLocalServer() . '/foo';
        $content = file_get_contents($url);

        $this->assertEquals('...', $content, 'Content mismatch');
    }
}

Methods

The following methods are provided to interact with the local server.

public bool LocalServerTestCase::createServerWithDocroot(string $docroot)

Creates a local server using a document root.

static::createServerWithDocroot('./path/to/site/files');

public bool LocalServerTestCase::createServerWithRouter(string $router)

Creates a local server using a router file. If you are using a framework, this is most likely the index.php file in your document route.

static::createServerWithRouter('./path/to/router.php');

public void LocalServerTestCase::destroyServer(void)

Removes the local server. Useful to reset the session state. This is automatically called in the tearDownAfterClass() lifecycle method.

static::destroyServer();

public string LocalServerTestCase::getServerUrl(void)

The port for the server will usually be 8000, however, it is dynamically assigned in the event of a conflict. The safest way to access the host is to call the getServerUrl() method and use that as the root for any Url construction.

$schemeHost = $this->getServerUrl();
$fullUrl    = $schemeHost . "/path/to/file/to/access";

echo $fullUrl; // http://localhost:8000/path/to/file/to/access
