模擬函數調用，但期望（$ this-> once（））失敗

Question

我正在測試Symfony命令發送提醒文本消息。爲此，我創建了一個服務，爲我的短信界面和我嘲諷容器以及該短信服務：

下測試

protected function textReminders() 
{ 
    $mailer = $this->getContainer()->get('mailer'); 
    $em = $this->getContainer()->get('doctrine')->getManager(); 


    if ($this->getContainer()->get('kernel')->getEnvironment() == 'dev'){ 
     $debug = true; 
    }else{ 
     $debug = false; 
    } 

    $textMessage = $this->getContainer()->get('text_messaging.interface'); 
    $textMessage->sendSMS($target, $content, $debug); 

} 

測試

private function getMockContainer() 
{ 
    $container = $this->getMockBuilder('Symfony\Component\DependencyInjection\Container') 
         ->disableOriginalConstructor() 
         ->setMethods(array('get')) 
         ->getMock(); 

    return $container; 
} 

protected function setupMocks() 
{ 
    $mockText = $this->getMockBuilder('TextaHQ') 
        ->disableOriginalConstructor() 
        ->setMethods(array('sendSMS')) 
        ->getMock(); 
    $mockContainer = $this->getMockContainer(); 

    $container = self::$kernel->getContainer(); 
    $mockContainer->method('get') 
     ->withConsecutive(['mailer'], ['doctrine'], ['kernel'], ['text_messaging.interface']) 
     ->willReturnOnConsecutiveCalls(
      $this->returnValue($container->get('mailer')), 
      $this->returnValue($container->get('doctrine')), 
      $this->returnValue(self::$kernel), 
      $this->returnValue($mockText)) 
    ; 

    $this->setMyMock([ 
         'text' => $mockText, 
         'container' => $mockContainer 
        ]); 
} 

public function testExecute() 
{ 
    $this->setupMocks(); 
    self::bootKernel(); 
    $application = new Application(self::$kernel); 

    $application->add(new ActionRemindCommand()); 

    $command = $application->find('ahp:remind'); 
    $command->setContainer($this->getMyMock()['container']); 
    $commandTester = new CommandTester($command); 

    $commandTester->execute(array(
            'command' => $command->getName(), 
            'type' => 'text' 
           )); 
    $output = $commandTester->getDisplay(); 

    $this->assertions(); 
} 

protected function assertions() 
{ 
    $this->getMyMock()['text'] 
     ->expects($this->once()) 
      ->method('sendSMS') 
      ; 

} 

功能

已更新測試，全部在一個文件中

public function testExecute() 
{ 
    $insertSql = 'echo "' 
     . str_replace(
      array('"' ,'`' ), 
      array('\\"' ,'\\`'), 
      $this->getPrepSql()) 
     . '" | mysql ahp_example_com'; 
    exec($insertSql); 

    self::bootKernel(); 

    $mockText = $this->getMockBuilder('TextaHQ') 
        ->disableOriginalConstructor() 
        ->setMethods(array('sendSMS')) 
        ->getMock(); 
    $mockContainer = $this->getMockBuilder('Symfony\Component\DependencyInjection\Container') 
             ->disableOriginalConstructor() 
             ->setMethods(array('get')) 
             ->getMock(); 

    $container = self::$kernel->getContainer(); 
    $mockContainer->method('get') 
        ->withConsecutive(['mailer'], ['doctrine'], ['kernel'], ['text_messaging.interface']) 
        ->willReturnOnConsecutiveCalls(
         $this->returnValue($container->get('mailer')), 
         $this->returnValue($container->get('doctrine')), 
         $this->returnValue(self::$kernel), 
         $this->returnValue($mockText)) 
    ; 


    $application = new Application(self::$kernel); 

    $application->add(new ActionRemindCommand()); 

    $mailer = self::$kernel->getContainer()->get('swiftmailer.mailer'); 
    $logger = new \Swift_Plugins_MessageLogger(); 
    $mailer->registerPlugin($logger); 
    $this->setMailCollector($logger); 

    $output = ''; 
    for($i=1;$i<=$this->getRunNoTimes();$i++) { 
     $command = $application->find('ahp:remind'); 
     $command->setContainer($mockContainer); 
     $commandTester = new CommandTester($command); 

     $commandTester->execute(array(
            'command' => $command->getName(), 
            'type' => 'text' 
           )); 
     $output .= $commandTester->getDisplay(); 
    } 

    $mockText 
     ->expects($this->once()) 
     ->method('sendSMS') 
    ; 
}

當我調試測試，我可以看到，$文字信息是一個模擬。

但是在斷言（）在測試結束時，我得到一個錯誤：

Expectation failed for method name is equal to <string:sendsms> when invoked 1 time(s). 
Method was expected to be called 1 times, actually called 0 times. 

調試器顯示的嘲笑功能爲小寫：「sendsms」，但重命名功能沒有幫助。

這裏是一個小illustartive案件，以澄清我在評論中提到的觀點。此外，它擁有時的期望所設置的情形失敗的測試進行實際工作中調用該方法後（這看起來是您的ALL-IN-一方法更新測試的情況。

class MyClass 
{ 
    public function someMethod(){ 

    } 
} 

class ExpectationsTest extends PHPUnit_Framework_TestCase 
{ 
    private $myClassMock; 

    public function setUp(){ 
     $this->myClassMock = $this->getMock('MyClass'); 
    } 

    public function testLocalMock(){ 
     $localMock = $this->getMock('MyClass'); 
     $localMock->expects($this->once()) 
        ->method('someMethod'); 
     $localMock->someMethod(); 
    } 

    public function testClassScopeMockInstance(){ 
     $this->myClassMock->expects($this->once()) 
          ->method('someMethod'); 
     $this->myClassMock->someMethod(); 
    } 

    public function testWillFailBecauseExpectationWasSetAfterCall(){ 
     $this->myClassMock->someMethod(); 
     $this->myClassMock->expects($this->once()) 
          ->method('someMethod'); 
    } 

    public function testCanUseHelperToCreateLocalMock(){ 
     $mock = $this->createMyClassMock(); 
     $mock->expects($this->once()) 
      ->method('someMethod'); 
     $mock->someMethod(); 
    } 

     private function createMyClassMock(){ 
      return $this->getMock('MyClass'); 
     } 

    public function testCanSetExpectationsInHelper(){ 
     $this->setExpecatationsOnTestCaseScopeMock(); 
     $this->myClassMock->someMethod(); 
    } 

     private function setExpecatationsOnTestCaseScopeMock(){ 
      $this->myClassMock->expects($this->once()) 
           ->method('someMethod'); 
     } 
} 

順便說一句，我認爲第一次我沒有足夠透徹地瞭解你的代碼，我想我可能錯過了你的setupMocks和getMyMock是如何工作的，對不起，
