PHP PHPUnit assertClassHasAttribute()用法及代码示例

assertClassHasAttribute()函数是PHPUnit中的内置函数,用于断言具有特定属性的类。如果该类包含所提供的属性,则此断言将返回true;否则返回false;如果为true,则断言了测试用例的通过否则测试用例失败。

用法

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

参数:该函数接受三个参数,如以上语法所示。参数说明如下:


  1. $attributeName:此参数表示要包含在类中的属性的名称。
  2. $className:此参数是一个字符串,作为要搜索其属性的类名。
  3. $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。

以下示例程序旨在说明assertClassHasAttribute()函数:

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") ; 
    } 
} 
  
?>

    public function testPositiveTestcaseForClassHasAttribute() 
    { 
        // assert function to test whether 'geeks' is a attribute of testclass
