PHP PHPUnit assertIsNotFloat()用法及代碼示例

assertIsNotFloat()函數是PHPUnit中的內置函數，用於斷言實際獲得的值是否不是浮點數。如果實際值不是Float，則此斷言將返回true；否則，Float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:

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

參數：該函數接受上述和以下所述的兩個參數：

• $actual:此參數可以是代表實際數據的任何類型的整數。
• $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assertIsNotFloat()函數：

範例1：

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeForassertIsNotFloat() 
    {    $actualvalue = (4.20); 
        // Assert function to test whether actual  
        // value is float or not 
        $this->assertIsNotFloat( 
          
            $actualvalue,  
            "actual value is float or not"
        ); 
          
    } 
   
 }  
?> 

輸出：
