我第一次遇到了mock/mock，我不确定下面的测试是否真的触及了我的代码，或者只是测试了我所做的mock ?此外，我意识到这段代码并不适合存储库模式，尽管它的名字是这样的。我会努力的。
类:
<?php namespace Acme'Cart'Repositories;
class EloquentCartRepository{
protected $model_name = 'CartModel';
protected $model;
public function __construct($model = null)
{
$this->model = is_null($model) ? new $this->model_name : $model;
}
public function create_visitor_cart($session_id,$type = 'main'){
return $this->create('visitor',$session_id,$type);
}
protected function create($user_type = null,$user_identifier = null,$type = 'main')
{
if(is_null($user_identifier)) throw new 'Exception('Cannot create create cart, missing user identifier');
if(is_null($user_type)) throw new 'Exception('Cannot create create cart, missing user type');
if($user_type == 'visitor')
{
$this->model->user_session_id = $user_identifier;
}
else
{
$this->model->user_id = $user_identifier;
}
$this->model->type = $type;
$this->model->save();
return $this->model;
}
}
和我的测试:
/** @test */
public function create_visitor_cart_calls_internal()
{
$model = m::mock('Models'CartModel');
$model->shouldReceive('user_session_id')->with('sess123');
$model->shouldReceive('type')->with('main');
$model->shouldReceive('save')->andReturn($model);
$repository = new EloquentCartRepository($model);
$created_model = $repository->create_visitor_cart('sess123','main');
$this->assertEquals('sess123',$created_model->user_session_id);
$this->assertEquals('main',$created_model->type);
}
这是一个合适的方式来测试我的类吗?或者这是对嘲弄/嘲讽的错误使用?
您不应该测试返回的内容，而应该测试它是否已保存。这意味着，->save()运行了。对->save()的期望是$model->shouldReceive('save')->andReturn($model);。这没有意义，因为代码没有使用->save()的返回值。
->save()方法是一个命令:它与数据库通信。所以它应该被嘲笑。要模拟对象，使用mock的->once()方法。它设置了一个期望，它应该被调用一次:
/** @test */
public function create_visitor_cart_calls_internal()
{
$model = m::mock('Models'CartModel');
$model->shouldReceive('save')->once();
$repository = new EloquentCartRepository($model);
$created_model = $repository->create_visitor_cart('sess123','main');
$this->assertEquals('sess123',$created_model->user_session_id);
$this->assertEquals('main',$created_model->type);
}
尽管它的名字，mock是一个默认的存根框架。它不会验证方法是否被调用，除非您显式地指定一个期望，如
->once()
