PHPUnit assertIsResource()函数

assertIsResource()函数是 PHPUnit 中的内置函数,用于断言给定变量是否为 Resource。如果给定变量是 Resource,则此断言将返回 true,否则返回 false。如果为真,则断言的测试用例通过,否则测试用例失败。

句法:

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

参数:此函数接受上述两个参数,如下所述:

  • $variable:此参数是代表实际数据的任何类型的变量。
  • $message:此参数采用字符串值。当测试用例失败时,此字符串消息显示为错误消息。

下面的例子说明了 PHPUnit 中的 assertIsResource()函数:

示例 1:

PHP
assertIsResource(
            $variable,
            "assert variable is resource or not"
        );
          
    }
   
 } 
?>


PHP
assertIsResource(
            $variable,
            "assert variable is Iterable or not"
        );
       fclose($variable);
  
    }
   
 } 
?>
