Unit testing laravel 4模拟-模拟模型关系

假设我有两个模型是从

扩展而来的，它们相互关联。我可以嘲笑这种关系吗

即：

在MyTest中，我当然希望创建一个模拟，并通过调用track属性而不是track实例来返回track的实例（我不希望使用查询生成器）

使用\ mockry作为m；
类MyTest扩展了TestCase{
公共功能设置（）
{
$track=新曲目（数组（'title'=>'foo'）；
$course=m:：mock（'course[track]'，数组（'track'=>$track））；
$track=$course->track//因为track是一个属性而不是一个方法，所以在创建模拟时，您需要覆盖模型的
setAttribute
和
getAttribute
方法。下面是一个解决方案，可以让您为要查找的属性设置期望值：

$track = new Track(array('title' => 'foo'));
$course = m::mock('Course[setAttribute,getAttribute]');
// You don't really care what's returned from setAttribute
$course->shouldReceive('setAttribute');
// But tell getAttribute to return $track whenever 'track' is passed in
$course->shouldReceive('getAttribute')->with('track')->andReturn($track);

模拟
课程
对象时，不需要指定
跟踪
方法，除非您也想测试依赖查询生成器的代码。如果是这种情况，则可以模拟
跟踪
方法，如下所示：

// This is just a bare mock object that will return your track back
// whenever you ask for anything. Replace 'get' with whatever method 
// your code uses to access the relationship (e.g. 'first')
$relationship = m::mock();
$relationship->shouldReceive('get')->andReturn([ $track ]);

$course = m::mock('Course[track]');
$course->shouldReceive('track')->andReturn($relationship);

$track = new Track(array('title' => 'foo'));
$course = m::mock('Course[setAttribute,getAttribute]');
// You don't really care what's returned from setAttribute
$course->shouldReceive('setAttribute');
// But tell getAttribute to return $track whenever 'track' is passed in
$course->shouldReceive('getAttribute')->with('track')->andReturn($track);

// This is just a bare mock object that will return your track back
// whenever you ask for anything. Replace 'get' with whatever method 
// your code uses to access the relationship (e.g. 'first')
$relationship = m::mock();
$relationship->shouldReceive('get')->andReturn([ $track ]);

$course = m::mock('Course[track]');
$course->shouldReceive('track')->andReturn($relationship);
