PHP PHPUnit assertClassNotHasStaticAttribute()用法及代码示例

assertClassNotHasStaticAttribute()函数是PHPUnit中的内置函数，用于断言不具有静态属性的类。如果该类不包含所提供的属性作为静态元素，则此断言将返回true；否则，返回false；如果为true，则通过断言的测试用例，否则测试用例失败。

用法：

assertClassNotHasStaticAttribute(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attributeName不能作为数组中类的属性。
2. $className：此参数是一个类名，assert函数将为其检查其是否包含属性。
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assertClassNotHasStaticAttribute()函数：

程序1:：

<?php 
use PHPUnit\Framework\TestCase; 
  
// test class 
Class testClass{ 
    public static $geeks = "test attribute"; 
} 
  
class GeeksPhpunitTestCase extends TestCase 
{ 
    public function testNegativeTestcaseForClassNotHasStaticAttribute() 
    { 
        // assert function to test whether 'geeks' is a attribute of testclass 
        $this->assertClassNotHasStaticAttribute('geeks', "testClass", "testClass  has geeks as static attribute") ; 
    } 
} 
?>

OK (1 test, 1 assertion)

注意：要使用phpunit运行测试用例，请遵循此处的步骤。
