PHP PHPUnit assertSame()用法及代碼示例

assertSame()函數是PHPUnit中的內置函數，用於斷言實際獲得的值是否與期望值相同。如果期望值與實際值相同，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:

assertSame(mixed $expected, mixed $actual[, string $message = ''])

參數：此函數接受上述和以下所述的三個參數：

$expected:此參數可以是代表期望數據的任何類型。
$actual: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assertSame()函數：

範例1：

PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeForassertSame() 
          
    { 
     $expected = "(108) banana";     
     $actual = "(108) mango"; 
        // Assert function to test whether expected 
        // value is same as actual value or not 
        $this->assertSame( 
            $expected, 
            $actual, 
            "actual value is not same as expected value"
        ); 
          
    } 
   
 }  
?>

輸出：
