使用PHPUnit中的Symfony路由器組件生成URL

Question

我正在嘗試在PHPUnit中編寫一個測試，以獲取基於Symfony路由的子域的URL的簡單方法。我不確定我的測試是否能夠正確訪問Symfony路由器組件，這就是爲什麼它會垮臺，但我目前似乎無法讓它通過。

這是我收到的錯誤：

There was 1 error:

1) CRMPiccoBundle\Tests\Services\MailerHelperTest::testReturnsBillingURL with data set "crmpicco.co.uk" (CRMPiccoBundle\Entity\Course Object (...), ' https://www.crmpicco.co.uk/en/admin/billing ') TypeError: Return value of CRMPiccoBundle\Services\MailerHelper::getBillingUrlForSubdomain() must be of the type string, null returned

這是我的測試和數據提供者：

/** 
* @dataProvider dataProvider 
*/ 
public function testReturnsBillingURL(Course $course, string $expectedUrl) 
{ 
    $mailerHelper = new MailerHelper($this->getRouterMock()); 
    $this->assertEquals($expectedUrl, $mailerHelper->getBillingUrlForSubdomain($course, true)); 
} 

public function dataProvider() 
{ 
    return [ 
     'crmpicco.co.uk' => [ 
      'site' => (new Course()) 
       ->setSubdomain('crmpicco'), 
      'expectedUrl' => 'https://www.crmpicco.co.uk/en/admin/billing', 
     ], 
    ]; 
} 

這是我getRouterMock方法：

/** 
* @return \Symfony\Bundle\FrameworkBundle\Routing\Router 
*/ 
protected function getRouterMock() 
{ 
    return $this->getMockBuilder('\Symfony\Bundle\FrameworkBundle\Routing\Router') 
     ->disableOriginalConstructor() 
     ->setMethods(['generate', 'supports', 'exists']) 
     ->getMockForAbstractClass(); 
} 

這是我正在測試的方法：

/** 
* @param Course $course 
* @param bool $absoluteUrl 
* 
* @return string 
*/ 
public function getBillingUrlForSubdomain(Course $course, bool $absoluteUrl = true) : string 
{ 
    return $this->router->generate('crmpiccobundle_portal_billing', [ 
     'subdomain' => $site->getSubdomain(), 
    ], $absoluteUrl); 
} 

Answer 1

但是你沒有得到正確的訪問Symfony路由器，你在嘲笑它。 而在這個模擬中，你沒有定義generate()方法調用返回什麼，所以難怪它返回null。

你缺少的部分是

/** 
* @return \Symfony\Bundle\FrameworkBundle\Routing\Router 
*/ 
protected function getRouterMock() 
{ 
    $mock = $this->getMockBuilder('\Symfony\Bundle\FrameworkBundle\Routing\Router') 
       ->disableOriginalConstructor() 
       ->setMethods(['generate', 'supports', 'exists']) 
       ->getMockForAbstractClass(); 

    $args = ['crmpiccobundle_portal_billing', [ 
     'subdomain' => "crmpicco", 
    ], true]; 

    $mock->expects($this->any()) 
     ->method('generate') 
     ->withArgs($args) 
     ->will($this->returnValue('https://www.crmpicco.co.uk/en/admin/billing')); 

    return $mock; 
}
