PHP PHPUnit assertIsNotString()用法及代碼示例

assertIsNotString()函數是PHPUnit中的內置函數，用於斷言實際獲得的值是否為非字符串值。如果實際值為Not Not else，則該斷言將返回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:

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

參數：此函數接受上述和以下描述的兩個參數：

• $actualvalue:此參數可以是代表實際數據的任何類型。
• $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assertIsNotString()函數：

範例1：

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeTestcaseForassertIsNotString() 
    { 
        $actualvalue = "22";  
    
        // Assert function to test whether given  
        // actualvalue is a string or not 
        $this->assertIsNotString( 
          $actualvalue, 
          "actualvalue is a string or not"
        );  
    }  
}  
    
?> 

輸出：

    { 
        $actualvalue = 420;  
    
        // Assert function to test whether given  
        // actualvalue is a string or not 
        $this->assertIsNotString(
