PHPUnit assertIsNumeric()函数

assertIsNumeric()函数是PHPUnit中的内置函数,用于断言给定的实际变量是否为数字。如果实际变量是数字,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:

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

参数:该函数接受上面提到的两个参数,如下所述:

  • $actual:这个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 assertIsNumeric()函数:

示例 1:

PHP
assertIsNumeric(
          
            $actualvalue, 
            "actual value is Numeric or not"
        );
          
    }
   
 } 
?>


PHP
assertIsNumeric(
          
            $actualvalue, 
            "actual value is Numeric or not"
        );
          
    }
   
 } 
?>
