giberti / phpunit-local-server
A local HTTP server for PHPUnit tests
Requires
- php: ^7.3 || ^8.0
- ext-posix: *
- phpunit/phpunit: ^8.0 || ^9.0
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
