Question

我正在使用Symfony Lock package检查类方法是否可以执行

if ($this->lock->acquire()) {
    $this->execute();
    $this->lock->release();
}

重要：我不是在使用Symfony框架，而是在使用Lock组件

我想做一个测试，断言在多个线程中运行时执行被锁定，但是我没有找到有关如何实现此目标的任何文档。

使用pthreads是个好主意吗？如果没有，那是进行此测试的最佳方法？

非常感谢您。

请参阅“锁定组件”文档： https://symfony.com/doc/current/components/lock.html#usage

CommandTester上的信息： https://symfony.com/doc/current/console.html#testing-commands

PHPUnit测试解决方案：

use Symfony\Component\Lock\Factory;
use Symfony\Component\Lock\Store\SemaphoreStore;

public function testLockIsSet()
{     
    // Create a new Semaphore lock with the same ID as the one that would be
    // created if you were running the command / class / process etc.
    $store = new SemaphoreStore();
    $factory = new Factory($store);
    $lock = $factory->createLock('lock-name-used-eg-generate-pdf');

    if ($lock->acquire()) {
        // In my use case I was running multiple commands to see if the lock
        // was working properly
        $commandTester = new CommandTester($this->command);

        // Try and run the command. The lock should already be set.
        $commandTester->execute(
            [
                'command'  => $this->command->getName()
            ]
        );

        // You could also use expectException() here for LogicException    
        $this->assertContains(
            'The command is already running in locked mode.',
            $commandTester->getDisplay()
        );

        $lock->release();
    }
}
