mock 寫法

• Quick start
  

  $stub = $this->getMockBuilder('modelAbc')
                         ->setMethods(array('findFirst'))
                         ->getMock();
  
  $stub->expects($this->any())
           ->method('findFirst')
           ->will($this->returnValue(null));

• 靜態寫法 (PHPUnit 3.9後就不支援static寫法了)
  

  $stub = $this->getMockClass(
              'modelAbc',
              array('findHistory')
          ) ;
  
  $stub::staticExpects($this->any())
              ->method('findHistory')
              ->will($this->returnValue($result));

method執行次數

Example:

$stub->expects($this->once())
->method('doSomething');

$this->once(); 只會被執行一次
$this->exactly(3); //只能3次
$this->any(); //不管幾次

method 回傳值

• 回傳固定值
  語法：$this->returnValue()
  Example:
  

  $stub->expects($this->any())
  ->method('doSomething')
  ->will($this->returnValue("Yes, sir!");

• 隨機回傳不同值
  語法：
  
• 依參數給回傳不同值
  語法：$this->returnValueMap(array(param1, ..., paramN, returnValue)
  Example:
  

  $stub->expects($this->any())
      ->method('doSomething')
      ->will(
          $this->returnValueMap(
              array(
              array('a', 'b', 'c', 'd'),
              array('e', 'f', 'g', 'h'))
          )
      )
  );
  $this->assertEquals('d', $stub->doSomething('a', 'b', 'c')); 
  $this->assertEquals('h', $stub->doSomething('e', 'f', 'g'));

Issue

• Phalcon\Mvc\Model\Exception: The method "__phpunit_getInvocationMocker" doesn't exist on model
  
  • Solution
    一般因為有namespace，只要補上完整的namespace即可
    

    $stub = $this->getMockBuilder('namespace_path\modelAbc');
