v3.1.0 2023-03-14 16:04 UTC


Allows to use attributes to define global variables in PHPUnit test cases.


Supported attributes:

  • #[Env] for $_ENV
  • #[Server] for $_SERVER
  • #[Putenv] for putenv()

Supported annotations:

  • @env and @unset-env for $_ENV
  • @server and @unset-server for $_SERVER
  • @putenv and @unset-getenv for putenv()

Annotations are deprecated since v3.1.0 and will be removed in the next major or minor version (whichever comes first). The latest annotation support is planned to be removed is when PHPUnit 11 is released. Annotation support is complete, so if you plan on using them keep using v3.1 of this package.

Global variables are set before each test case is executed, and brought to the original state after each test case has finished. The same applies to putenv()/getenv() calls.



composer require --dev zalas/phpunit-globals


The extension is also distributed as a PHAR, which can be downloaded from the most recent Github Release.

Put the extension in your PHPUnit extensions directory. Remember to instruct PHPUnit to load extensions in your phpunit.xml:

<phpunit xmlns:xsi="" xsi:noNamespaceSchemaLocation="file://./vendor/phpunit/phpunit/phpunit.xsd"


Enable the globals attribute extension in your PHPUnit configuration:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit xmlns:xsi=""

    <!-- ... -->

        <bootstrap class="Zalas\PHPUnit\Globals\AttributeExtension" />

If you are using a version before PHP 8.1 you can use the AnnotationExtension instead.

Make sure the AttributeExtension is registered before any other extensions that might depend on global variables.

Global variables can now be defined in attributes:

use PHPUnit\Framework\TestCase;
use Zalas\PHPUnit\Globals\Attribute\Env;
use Zalas\PHPUnit\Globals\Attribute\Server;
use Zalas\PHPUnit\Globals\Attribute\Putenv;

 * @env FOO=bar
class ExampleTest extends TestCase
    #[Env('APP_ENV', 'foo')]
    #[Env('APP_DEBUG', '0')]
    #[Server('APP_ENV', 'bar')]
    #[Server('APP_DEBUG', '1')]
    #[Putenv('APP_HOST', 'localhost')]
    public function test_global_variables()
        $this->assertSame('bar', $_ENV['FOO']);
        $this->assertSame('foo', $_ENV['APP_ENV']);
        $this->assertSame('0', $_ENV['APP_DEBUG']);
        $this->assertSame('bar', $_SERVER['APP_ENV']);
        $this->assertSame('1', $_SERVER['APP_DEBUG']);
        $this->assertSame('localhost', \getenv('APP_HOST'));

It's also possible to mark a variable as unset so it will not be present in any of the global variables:

use PHPUnit\Framework\TestCase;

class ExampleTest extends TestCase
    #[Env('APP_ENV', unset: true)]
    #[Server('APP_DEBUG', unset: true)]
    #[Putenv('APP_HOST', unset: true)]
    public function test_global_variables()
        $this->assertArrayNotHasKey('APP_ENV', $_ENV);
        $this->assertArrayNotHasKey('APP_DEBUG', $_SERVER);
        $this->assertArrayNotHasKey('APP_HOST', \getenv());

Updating to PHPUnit 10

When updating from a previous version of this extension dedicated to work with PHPUnit 9, replace the extension registration in phpunit.xml:

        <extension class="Zalas\PHPUnit\Globals\AttributeExtension" />


        <bootstrap class="Zalas\PHPUnit\Globals\AttributeExtension" />
