我正在尝试在PHPunit中配置Mock对象以返回不同属性的值(使用__get函数访问)
示例:
class OriginalObject {
public function __get($name){
switch($name)
case "ParameterA":
return "ValueA";
case "ParameterB":
return "ValueB";
}
}
我试图用以下方法来嘲笑:
$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"));
但这很可怕: - (

我还没有尝试过嘲笑__get,但也许这会起作用:
// 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()并且它可以工作(但不是最佳解决方案)。我从这个方面得到了它:
How can I get PHPUnit MockObjects to return different values based on a parameter?

这应该有效:
class Test extends \PHPUnit_Framework_TestCase {
...
function testSomething() {
$mockObject = $this->getMock("OrigionalObject");
$mockObject
->expects( $this->any() )
->method('__get')
->will( $this->returnCallback('myMockGetter'));
...
}
...
}
function myMockGetter( $classPropertyName ) {
switch( $classPropertyName ) {
case 'ParameterA':
return 'ValueA';
case 'ParameterB':
return 'ValueB';
}
}
... ...
