PHPUnit RabbitMQ:创建连接功能的编写测试 [英] PHPUnit RabbitMQ: write test for create connection function

问题描述

我正面临以下问题.我编写了一个函数，该函数根据给定的参数创建连接对象(AMQPConnection).现在我要编写相应的单元测试.我只是不运行RabbitMQ代理就不知道该怎么做.这是有问题的功能:

I'm facing the following problem. I've wrote a function that create a connection object (AMQPConnection) given the required parameters. Now I want to write the corresponding unit test. I just don't know how to do it without having the RabbitMQ broker running. Here is the function in question:

public function getConnection($hostKey, array $params)
{
    $connection = null;
    try {

        $connection = new AMQPConnection(
            $params['host'],
            $params['port'],
            $params['username'],
            $params['password'],
            $params['vhost']
        );

        // set this server as default for next connection connectionAttempt
        $this->setDefaultHostConfig($hostKey, $params);

        return $connection;
    } catch (\Exception $ex) {

        if ($this->isAttemptExceeded()) {
            return $connection;
        } else {
            // increment connection connectionAttempt
            $this->setConnectionAttempt($this->getConnectionAttempt() + 1);

            return $this->getConnection($hostKey, $params);
        }
    }
}

推荐答案

您通常不将这样的代码作为单元测试进行测试，因为结果很可能会告诉您服务器已正确安装，而不是代码可以正常工作

You usually don't test code like this as a Unittest since the result would more likely tell you that your server is installed correctly and not that your code is working.

您是否测试PDO是否返回有效的数据库连接?

Do you test if PDO returns a valid database connection?

如果您测试安装，但没有测试php c库是否正常运行，这可能很有意义.

It could make sense if you test your installation but not to test if the php c libs are working correctly.
