composer require --dev amphp/phpunit-util<?php namespace Foo; use Amp\ByteStream; use Amp\PHPUnit\AsyncTestCase; use Amp\Socket; class BarTest extends AsyncTestCase { // Each test case is executed as a coroutine and checked to run to completion public function test() { $socket = yield Socket\connect('tcp://localhost:12345'); yield $socket->write('foobar'); $this->assertSame('foobar', yield ByteStream\buffer($socket)); } }This package also provides a PHPUnit TestListener to reset the global event loop after each test, but this is deprecated.
