wyrihaximus/react-phpunit-run-tests-in-fiber
PHPUnit trait to run each test inside a PHP Fiber, making it easy to use ReactPHP async/await in tests. Includes optional per-test or per-class timeout attributes to fail slow tests (without stopping the running fiber).
<?php
declare(strict_types=1);
use PHPUnit\Framework\TestCase;
use React\Promise\Promise;
use WyriHaximus\React\PHPUnit\RunTestsInFibersTrait;
use function React\Asyncwait;
final class SomeTest extends TestCase
{
use RunTestsInFibersTrait;
/**
* [@test](https://github.com/test)
*/
public function happyFlow()
{
self::assertTrue(await(new Promise(static function (callable $resolve): void {
$resolve(true);
})));
}
}
This package supports marking a test failed once a timeout has been reached. Note that this doesn't stop anything running in the fiber the rest runs in or cleans up the loop as we cannot kill the running fiber once it starts. An exception is thrown in the scope between the test and PHPUnit that handles running the test in a fiber. And this is out of control of the test.

use function React\Asyncwait;
