PHPUnit接收系统日志消息？

问题描述：

I am testing a logger class with a method that opens a log like so:

openlog($this->identifier, $this->option, $this->facility);
syslog($level, $message)
closelog();

The $facility that my logger writes to is currently set as LOCAL0

When I unit test my logger I get the following message:

Broadcast message from systemd-journald@myWS:

phpserver7.0[9125]: Logger message

How can I suppress this message with PHPUnit or in my code?

Edit:

This only seems to happen when I log a message with a severity of "emergency" meaning a severity level of 0.

https://en.wikipedia.org/wiki/Syslog#Severity_level

Wikipedia states:

This level should not be used by applications.

Still, it is part of the PSR-3 logger abstract though so I would just like to be able to suppress the message with PHPUnit.

我正在使用打开日志的方法测试记录器类： p>

  openlog（$ this-＆gt; identifier，$ this-＆gt; option，$ this-＆gt; facility）; 
syslog（$ level，$ message）
closelog（）; 
  code>   pre> 
 
 我的记录器写入的 $ facility  code>当前设置为 LOCAL0  code>  p> 
 
 
 我对我的记录器进行单元测试我收到以下消息： p> 
 
 

 来自systemd-journald的广播消息@myWS：
 
 
nphpserver7.0 [9125]：记录消息
   code>  pre> 
 
 如何使用PHPUnit或我的代码抑制此消息？ p>

 只有当我记录严重性为“紧急”的消息时才会出现这种情况，这意味着严重性级别为0.  p>

维基百科声明： p>  
 
 
 
 应用程序不应使用此级别。 p  >

尽管如此，它仍然是PSR-3记录器摘要的一部分，所以我只想用PHPUnit来抑制消息。 p>

答

In your test method, you can suppress output by wrapping an output buffer around your call that produces output. Example:

/**
 * @preserveGlobalState disabled
 * @runInSeparateProcess
 */
public function testOutputCanSend()
{
    ob_start();

    // Do some stuff here that outputs directly, e.g
    openlog($this->identifier, $this->option, $this->facility);
    syslog($level, $message)
    closelog();

    ob_end_clean();
}
