How to simulate the properties of an object?

Question

I am trying to make fun of properties, but cannot make it work. In this case, I am trying to make fun of a query property Symfony\Component\HttpFoundation\Request.

According to this answer, I have to return a value for__get

The following code continues to show NULL:

$testRequest = $this->getMockBuilder('Symfony\Component\HttpFoundation\Request')
  ->disableOriginalConstructor()
  ->getMock();
$testRequest->expects($this->any())
  ->method('__get')
  ->with($this->equalTo('request'))
  ->will($this->returnValue("working"));
var_dump($testRequest->request);

Maybe because the answer is too old, so check the current documentation of mockery, but this does not mention how to mock properties at all.

According to another answer, I can try the following:

private $post=array('search'=>'abc','start'=>null);
...
$paramBag = $this->getMockBuilder('Symfony\Component\HttpFoundation\ParameterBag')
  ->disableOriginalConstructor()
  ->getMock();
foreach($this->post as $key=>$value){
  echo "setting:".$key.' with:'.$value.PHP_EOL;              
  $paramBag->expects($this->any())
    ->method('get')
    ->with($this->equalTo($key))
    ->will($this->returnValue($value));
}
$this->request = $this->getMockBuilder('Symfony\Component\HttpFoundation\Request')
  ->disableOriginalConstructor()
  ->getMock();
$this->request->request=$paramBag;
echo ($this->request->request->get('start'));

This gives me:

Expectation failed for method name is equal to <string:get> when invoked zero or more times
Parameter 0 for invocation Symfony\Component\HttpFoundation\ParameterBag::get('search', null, false) does not match expected value.
Failed asserting that two strings are equal.

Is it not possible to override multiple methods with different values? Again, the documentation is completely missing any examples of this.

echo ($this->request->request->get('start'));, , . -, .

private/protected, , :

$reflection = new \ReflectionClass($objectThatContainsThePropertyToMock);
$property   = $reflection->getProperty($propertyName);
$property->setAccessible(true);
return $property->setValue($mockedObject);
