如何測試廣播驅動程序？

Question

我想知道是否有可能在Laravel測試ShouldBroadcast？ 我的測試會觸發甚至執行ShouldBroadcast，但是，我注意到廣播沒有發生。

當然，廣播事件正在它自己的應用程序中工作。

有沒有人試過這樣的測試？

這是一個古老的問題，但以防萬一它可以幫助某人：我爲自己做了一個斷言函數，您應該添加到您的TestCase.php。

這個想法是將廣播驅動程序設置爲「日誌」，然後從結尾讀取第4行以查看它是否是廣播日誌。

在你phpunit.xml

如下因素行添加到節點：

<env name="BROADCAST_DRIVER" value="log"/> 

在你TestCase.php文件

添加如下因素的功能：

public function assertEventIsBroadcasted($eventClassName, $channel=""){ 
    $logfileFullpath = storage_path("logs/laravel.log"); 
    $logfile = explode("\n", file_get_contents($logfileFullpath)); 

    if(count($logfile) > 4){ 
    $supposedLastEventLogged = $logfile[count($logfile)-5]; 

    $this->assertContains("Broadcasting [", $supposedLastEventLogged, "No broadcast were found.\n"); 

    $this->assertContains("Broadcasting [".$eventClassName."]", $supposedLastEventLogged, "A broadcast was found, but not for the classname '".$eventClassName."'.\n"); 

    if($channel != "") 
     $this->assertContains("Broadcasting [".$eventClassName."] on channels [".$channel."]", $supposedLastEventLogged, "The expected broadcast (".$eventClassName.") event was found, but not on the expected channel '".$channel."'.\n"); 
    }else{ 
    $this->fail("No informations found in the file log '".$logfileFullpath."'."); 
    } 
}
