Trait to run all tests in a fiber

Install

To install via Composer, use the command below, it will automatically detect the latest version and bind it with ^.

composer require wyrihaximus/react-phpunit-run-tests-in-fiber

Usage

<?php

declare(strict_types=1);

use PHPUnit\Framework\TestCase;
use React\Promise\Promise;
use WyriHaximus\React\PHPUnit\RunTestsInFibersTrait;

use function React\Async\await;

final class SomeTest extends TestCase
{
    use RunTestsInFibersTrait;

    /**
     * @test
     */
    public function happyFlow()
    {
        self::assertTrue(await(new Promise(static function (callable $resolve): void {
            $resolve(true);
        })));
    }
}

Timeouts

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.

<?php

declare(strict_types=1);

use PHPUnit\Framework\TestCase;
use React\Promise\Promise;
use WyriHaximus\React\PHPUnit\RunTestsInFibersTrait;
use WyriHaximus\React\PHPUnit\TimeOut;

use function React\Async\await;

#[TimeOut(30)]
final class SomeTest extends TestCase
{
    use RunTestsInFibersTrait;

    /**
     * @test
     */
    #[TimeOut(0.1)]
    public function happyFlow()
    {
        self::assertTrue(await(new Promise(static function (callable $resolve): void {
            $resolve(true);
        })));
    }
}
