PHP PHPUnit assertNotSame()用法及代码示例

assertNotSame()函数是PHPUnit中的内置函数，用于将实际获得的值not-same声明为期望值。如果预期值为not-same到实际值，则此断言将返回true，否则返回false。如果为真，则通过断言的测试用例，否则测试用例失败。

用法:

assertNotSame( mixed $expected, mixed $actual, string $message = '' )

参数：该函数接受三个参数，如上面的语法所示。参数说明如下：

$expected:此参数可以是代表期望数据的任何类型。
$actual:此参数可以是代表实际数据的任何类型。
$message:此参数采用字符串值。当测试用例失败时，此字符串消息将显示为错误消息。

以下示例说明了PHPUnit中的assertNotSame()函数：

范例1：

PHP

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

{  
    public function testPositiveForassertNotSame() 
          
    { 
     $expected = "(108) banana";     
     $actual = "(108) mango"; 
        // Assert function to test whether expected 
        // value is same as actual value or not 
        $this->assertNotSame( 
            $expected, 
            $actual, 
            "actual value is same to expected"
        ); 
          
    } 
   
 }  
?>
