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(使用 __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)

例子:

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

我正在尝试使用:

$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"));

但这非常失败:-(

推荐答案

我还没有尝试模拟 __get，但也许这会起作用:

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() 并且它有效(但不是最佳解决方案).我是从这个胎面得到的:

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

如何我可以让 PHPUnit MockObjects 根据参数返回不同的值吗?
