PHP PHPUnit assertIsResource()用法及代碼示例

assertIsResource()函數是PHPUnit中的內置函數，用於斷言給定變量是否為Resource。如果給定變量為Resource，則此斷言將返回true，否則返回false。如果為真，則通過斷言的測試用例，否則測試用例失敗。

用法:

assertIsResource($actual[, $message = ''])

參數：此函數接受上麵和下麵描述的兩個參數：

$variable:此參數可以是代表實際數據的任何類型的變量。
$message:此參數采用字符串值。當測試用例失敗時，此字符串消息將顯示為錯誤消息。

以下示例說明了PHPUnit中的assertIsResource()函數：

範例1：

PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeTestcaseForassertIsResource() 
    {  
       $variable =  555; 
        // Assert function to test whether assert 
        //  variable is resource or not 
        $this->assertIsResource( 
            $variable, 
            "assert variable is resource or not"
        ); 
          
    } 
   
 }  
?>

輸出：

class GeeksPhpunitTestCase extends TestCase  
{  
    public function testPositiveTestcaseForassertIsResource() 
    {  
       $variable =  fopen('http://www.google.com','r'); 
        // Assert function to test whether assert 
        //  variable is Iterable 
        $this->assertIsResource( 
            $variable, 
            "assert variable is Iterable or not"
        ); 
       fclose($variable); 
  
    } 
   
 }  
?>
