PHP PHPUnit assertIsNumeric()用法及代碼示例

assertIsNumeric()函數是PHPUnit中的內置函數,用於斷言給定的實際變量是否為數字。如果實際變量為數字,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:

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

參數:此函數接受上述和以下描述的兩個參數:

  • $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assertIsNumeric()函數:

範例1:



PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeForassertIsNumeric() 
    {    
     $actualvalue = "hello"; 
        // Assert function to test whether actual  
        // variable is numeric or not 
        $this->assertIsNumeric( 
          
            $actualvalue,  
            "actual value is Numeric or not"
        ); 
          
    } 
   
 }  
?> 

輸出:

PHPUnit 8.5.8 by Sebastian Bergmann and contributors.

F                                                 1 / 1 (100%)

範例2:

PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testPositiveForassertIsNumeric() 
    {    
     $actualvalue = "1111"; 
        // Assert function to test whether actual  
        // variable is numeric or not 
        $this->assertIsNumeric( 
          
            $actualvalue,  
            "actual value is Numeric or not"
        ); 
          
    } 
   
 }  
?> 

輸出:
