PHPUnit-创建Mock对象以充当属性的存根 [英] PHPUnit - creating Mock objects to act as stubs for properties

问题描述

我正在尝试在PHPunit中配置一个Mock对象，以返回不同属性的值(可通过__get函数访问)

I'm trying to configure a Mock object in PHPunit to return values for different properties (that are accessed using the __get function)

示例:

class OriginalObject {
 public function __get($name){
switch($name)
 case "ParameterA":
  return "ValueA";
 case "ParameterB":
  return "ValueB";
 }
}

我正在尝试使用以下方法来模拟它:

I'm trying to mock this using:

$mockObject = $this->getMock("OrigionalObject");

$mockObject    ->expects($this->once())
    ->method('__get')
    ->with($this->equalTo('ParameterA'))
    ->will($this->returnValue("ValueA"));

$mockObject    ->expects($this->once())
    ->method('__get')
    ->with($this->equalTo('ParameterB'))
    ->will($this->returnValue("ValueB"));

但这失败了很可怕:-(

but this fails horribly :-(

推荐答案

我还没有尝试过__get的模拟，但这也许可以工作:

I haven't tried mocking __get yet, but maybe this will work:

// getMock() is deprecated
// $mockObject = $this->getMock("OrigionalObject");
$mockObject = $this->createMock("OrigionalObject");

$mockObject->expects($this->at(0))
    ->method('__get')
    ->with($this->equalTo('ParameterA'))
    ->will($this->returnValue('ValueA'));

$mockObject->expects($this->at(1))
    ->method('__get')
    ->with($this->equalTo('ParameterB'))
    ->will($this->returnValue('ValueB'));

我已经在测试中使用了$ this-> at()，它可以工作(但不是最佳解决方案).我是从这个脚步得到的:

I've already used $this->at() in a test and it works (but isn't an optimal solution). I got it from this tread:

如何我该如何使PHPUnit MockObjects根据参数返回不同的值?
