PHP PHPUnit assertClassHasAttribute()用法及代碼示例

assertClassHasAttribute()函數是PHPUnit中的內置函數，用於斷言具有特定屬性的類。如果該類包含所提供的屬性，則此斷言將返回true;否則返回false;如果為true，則斷言了測試用例的通過否則測試用例失敗。

用法：

assertClassHasAttribute(string $attributeName, string $className[, string $message = ''])

參數：該函數接受三個參數，如以上語法所示。參數說明如下：

1. $attributeName：此參數表示要包含在類中的屬性的名稱。
2. $className：此參數是一個字符串，作為要搜索其屬性的類名。
3. $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。

以下示例程序旨在說明assertClassHasAttribute()函數：

程序1:：

<?php 
use PHPUnit\Framework\TestCase; 
  
// test class 
Class testClass{ 
    public $attribute = "test attribute"; 
} 
  
class GeeksPhpunitTestCase extends TestCase 
{ 
    public function testNegativeTestcaseForClassHasAttribute() 
    { 
        // assert function to test whether 'geeks' is a attribute of testclass 
        $this->assertClassHasAttribute('geeks', "testClass", "testClass doesn't has geeks as attribute") ; 
    } 
} 
  
?>
