如何为Zend framework 2 cookies编写测试用例？

Question

我已经写了要读取和写入cookie的实用类。我没有想法为我的实用程序类编写测试用例。

我怎样才能通过使用Zend Framework 2 HTTP /客户编写测试用例？
测试此实用程序类是强制性的吗？ （因为它使用默认的Zend Framework的方法）

class Utility 
{ 
    public function read($request, $key){//code} 

    public function write($reponse, $name, $value) 
    { 
    $path = '/'; 
    $expires = 100; 
    $cookie = new SetCookie($name,$value, $expires, $path); 
    $response->getHeaders()->addHeader($cookie); 
    } 
}

是：如果依靠这片逻辑的我会测试该代码。当您调用此方法时，知道cookie始终设置为给定值很重要。

一个办法看你如何测试片是从SlmLocale一个例子：写入可能的语言环境下来到一个cookie一个ZF2区域检测模块。你可以找到代码in the tests。

你的情况：

use My\App\Utility; 
use Zend\Http\Response; 

public function setUp() 
{ 
    $this->utility = new Utility; 
    $this->response = new Response; 
} 
public function testCookieIsSet() 
{ 
    $this->utility->write($this->response, 'foo', 'bar'); 

    $headers = $this->response->getHeaders(); 
    $this->assertTrue($headers->has('Set-Cookie')); 
} 

public function testCookieHeaderContainsName() 
{ 
    $this->utility->write($this->response, 'foo', 'bar'); 

    $headers = $this->response->getHeaders(); 
    $cookie = $headers->get('Set-Cookie'); 
    $this->assertEquals('foo', $cookie->getName()); 
} 

public function testCookieHeaderContainsValue() 
{ 
    $this->utility->write($this->response, 'foo', 'bar'); 

    $headers = $this->response->getHeaders(); 
    $cookie = $headers->get('Set-Cookie'); 
    $this->assertEquals('bar', $cookie->getValue()); 
} 

public function testUtilitySetsDefaultPath() 
{ 
    $this->utility->write($this->response, 'foo', 'bar'); 

    $headers = $this->response->getHeaders(); 
    $cookie = $headers->get('Set-Cookie'); 
    $this->assertEquals('/', $cookie->getPath()); 
} 

public function testUtilitySetsDefaultExpires() 
{ 
    $this->utility->write($this->response, 'foo', 'bar'); 

    $headers = $this->response->getHeaders(); 
    $cookie = $headers->get('Set-Cookie'); 
    $this->assertEquals(100, $cookie->getExpires()); 
}
