如何在 Laravel 单元测试期间获取视图数据

How to get view data during unit testing in Laravel

提问by Claire

I would like to check the array given to a view in a controller function has certain key value pairs. How do I do this using phpunit testing?

我想检查在控制器函数中提供给视图的数组是否具有某些键值对。我如何使用 phpunit 测试来做到这一点？

//my controller I am testing


public function getEdit ($user_id)
{
    $this->data['user'] = $user = \Models\User::find($user_id);

    $this->data['page_title'] = "Users | Edit";

    $this->data['clients'] = $user->account()->firstOrFail()->clients()->lists('name', 'id');

    $this->layout->with($this->data);

    $this->layout->content = \View::make('user/edit', $this->data);
}

//my test
public function testPostEdit (){

    $user = Models\User::find(parent::ACCOUNT_1_USER_1);

    $this->be($user);

    $response = $this->call('GET', 'user/edit/'.parent::ACCOUNT_1_USER_1);   

    //clients is an array.  I want to get this 
    //array and use $this->assetArrayContains() or something
    $this->assertViewHas('clients');

    $this->assertViewHas('content');

}

I found a better way to do it. I wrote a function in the TestCase which returns the array I want from the view data.

我找到了一个更好的方法来做到这一点。我在 TestCase 中编写了一个函数，它从视图数据中返回我想要的数组。

protected function getResponseData($response, $key){

    $content = $response->getOriginalContent();

    $content = $content->getData();

   return $content[$key]->all();

}

So to get a value from the $data object I simply use $user = $this->getResponseData($response, 'user');

所以为了从 $data 对象中获取一个值，我只是使用 $user = $this->getResponseData($response, 'user');

Inside a test case use:

在测试用例中使用：

$data = $this->response->getOriginalContent()->getData();

$data = $this->response->getOriginalContent()->getData();

Example:

例子：

<?php

use Illuminate\Foundation\Testing\WithoutMiddleware;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\DatabaseTransactions;

class HomeTest extends TestCase
{
    /**
     * A basic test example.
     *
     * @return void
     */
    public function testExample()
    {
        $data = $this->response->getOriginalContent()->getData();

        // do your tests on the data
    }
}

Example dumping data so you can see what in data(array) passed to view:

示例转储数据，以便您可以查看传递给视图的数据（数组）中的内容：

<?php

use Illuminate\Foundation\Testing\WithoutMiddleware;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\DatabaseTransactions;

class HomeTest extends TestCase
{
    /**
     * A basic test example.
     *
     * @return void
     */
    public function testExample()
    {
        $data = $this->response->getOriginalContent()->getData();
        dd($data);
    }
}

Should get something back like what's in image:

应该得到一些像图像中的东西：

So looking at how assertViewHasis implemented HEREit looks like, what the method does, is access the view's data after this call:

所以看看这里assertViewHas是如何实现的，方法的作用是在这个调用之后访问视图的数据：

$response = $this->client->getResponse()->original;

In your code, the line:

在您的代码中，该行：

$response = $this->call('GET', 'user/edit/'.parent::ACCOUNT_1_USER_1);

essentially returns the same thing as the line above it, namely a \Illuminate\Http\Response(which extends the symfony component \HttpFoundation\Response)

基本上返回与其上方的行相同的内容，即 a \Illuminate\Http\Response（扩展 symfony 组件\HttpFoundation\Response）

So, inside the assertViewHasfunction it looks like laravel accesses the data using $response->$key, so I would try to access the clientsand 'content' variables through the $responseobject.

因此，在assertViewHas函数内部，看起来 laravel 使用 访问数据$response->$key，所以我会尝试clients通过$response对象访问和 'content' 变量。

If that doesn't work try searching around the TestCasefile in the Laravel framework ... I'm sure the answer is in there somewhere. Also try to dump the $responseobject and see what it looks like, there should be some clues there.

如果这不起作用，请尝试在TestCaseLaravel 框架中搜索文件……我相信答案就在某个地方。也尝试转储$response对象，看看它是什么样子，那里应该有一些线索。

The first thing I would try, though, is accessing your data through the $responseobject.

不过，我要尝试的第一件事是通过$response对象访问您的数据。

I managed it by doing it in a messy way. I used assertViewHas:

我通过以凌乱的方式进行管理。我用过assertViewHas：

$this->assertViewHas('clients', array('1' => 'Client 1', '6' => 'Client2'));

You can access data in the response and it can be checked..

您可以访问响应中的数据并且可以检查它。

public function testSimpleLastProducts() {        

    $res = $this->call('GET', '/');

    $this->assertResponseOk();

    $this->assertViewHas('lastProducts');

    $lastProductOnView = $res->original['lastProducts'];

    $this->assertEquals(6, count($lastProductOnView));       

}

Looking for something like this in 2019, I got: $response->getData()->data[0]->...my properties

在 2019 年寻找这样的东西，我得到了： $response->getData()->data[0]->...my properties

Still looking for a simpler way to access it.

仍在寻找一种更简单的方法来访问它。

This worked for me:

这对我有用：

$response->getSession()->get("errors")

And from there you can check the contents of the message box for whatever error you might want verify.

从那里您可以检查消息框的内容是否有您可能想要验证的错误。
