Question

我正在尝试学习UnitTest如何在laravel上工作。我理解如何测试控制器和模型。我不明白的是如何测试我自己的课程。

我们举个例子说：

我在app/core/chat/chat.php创建了一个名为Chat的课程。在这种情况下，我想测试我的第一个方法load()。如何告诉班级ChatTest我想测试该方法？

我尝试在我的方法上实例化该类传递模拟接口（在IoC上绑定）并说当前类应该加载一次加载，但是它给出了一个错误，即方法加载应该被调用一次但是它被调用0次我在哪里弄错了？

<?php namespace Core\Chat\Chat;

use Core\Chat\Chat\Models\MessageInterface;
use Core\Chat\Chat\Models\ConversationInterface;

Class Chat { 
    function __construct(ConversationInterface $conversation,MessageInterface $message) { 
        $this->conversation = $conversation;
        $this->message = $message;
        $this->app = app();
    }

    /**
    * Get Messages of a conversation, on the current user
    *
    * @param $user_id | id user id
    * @return Bool | true | False
    */

    public function load($user_id) {
        $conversation = $this->exist( $user_id, $this->app['sentry']->getUser()->id );
        if ($conversation) {
            $messages = $this->conversation->loadConversation($conversation->id);    
            $this->status = "success";
            $this->response = $messages;
            return true;
        } else {
            $this->status = "error";
            $this->response = "no conversation";
            return false;
        }
    }
}

Class ChatTest

<?php

use \Mockery;

/**
 * Class ChatTest
 */
class ChatTest extends TestCase { 
    public function tearDown()
    {
        Mockery::close();
    }

    public function test_load_messages_conversation() {    
        $convInterface = Mockery::mock('Core\Chat\Chat\Models\ConversationInterface');
        $messInterface = Mockery::mock('Core\Chat\Chat\Models\MessageInterface');
        $chat = new Chat($convInterface,$messInterface);
        $chat->shouldReceive('load')->once();
        // error it should be called 1 time but it called 0 times.              
    }
}

问题是你需要在Mockery实例中调用 shouldReceive ，那些在Chat类中调用但不属于该类的方法，所以当你测试Chat类时，你不依赖于其他类别的回复。在这种情况下这样的事情（不是一个完全正常的代码，但希望能给你一些我在这种情况下会做的事情）：

$sentryMock->shouldReceive('getUser')->andReturn(new User);
$convMock->shouldReceive('loadConversation')->andReturn(new MessageInterface);
$chat = new Chat(); //should be working with IoC bindings
$this->assertTrue($chat->load());
