如何测试 Laravel 社交名流

Question

我有一个使用社交名流的应用程序，我想为 Github 身份验证创建测试，所以我使用 Socialite Facade 来模拟对 Socialite driver 方法的调用，但是当我运行测试时它告诉我我是试图获取 null 类型的值。

下面是我写的测试

public function testGithubLogin()
{
    Socialite::shouldReceive('driver')
        ->with('github')
        ->once();
    $this->call('GET', '/github/authorize')->isRedirection();
}

下面是测试的实现

public function authorizeProvider($provider)
{
    return Socialite::driver($provider)->redirect();
}

我理解它为什么会返回这样的结果，因为Sociallite::driver($provider) 返回了Laravel\Socialite\Two\GithubProvider 的一个实例，并且考虑到我无法实例化该值，因此无法指定返回类型。我需要帮助才能成功测试控制器。谢谢

Answer 1

嗯，两个答案都很棒，但是它们有很多不需要的代码，我能够从它们中推断出我的答案。

这就是我需要做的。

首先模拟社交名流用户类型

$abstractUser = Mockery::mock('Laravel\Socialite\Two\User')

其次，为其方法调用设置期望值

$abstractUser
   ->shouldReceive('getId')
   ->andReturn(rand())
   ->shouldReceive('getName')
   ->andReturn(str_random(10))
   ->shouldReceive('getEmail')
   ->andReturn(str_random(10) . '@gmail.com')
   ->shouldReceive('getAvatar')
   ->andReturn('https://en.gravatar.com/userimage');

第三，你需要模拟提供者/用户调用

Socialite::shouldReceive('driver->user')->andReturn($abstractUser);

最后你写你的断言

$this->visit('/auth/google/callback')
     ->seePageIs('/')

Answer 2

$provider = Mockery::mock('Laravel\Socialite\Contracts\Provider');
$provider->shouldReceive('redirect')->andReturn('Redirected');
$providerName = class_basename($provider);
//Call your model factory here
$socialAccount = factory('LearnCast\User')->create(['provider' => $providerName]);

$abstractUser = Mockery::mock('Laravel\Socialite\Two\User');
// Get the api user object here
$abstractUser->shouldReceive('getId') 
             ->andReturn($socialAccount->provider_user_id)
             ->shouldReceive('getEmail')
             ->andReturn(str_random(10).'@noemail.app')
             ->shouldReceive('getNickname')
             ->andReturn('Laztopaz')
             ->shouldReceive('getAvatar')
             ->andReturn('https://en.gravatar.com/userimage');

$provider = Mockery::mock('Laravel\Socialite\Contracts\Provider');
$provider->shouldReceive('user')->andReturn($abstractUser);

Socialite::shouldReceive('driver')->with('facebook')->andReturn($provider);

// After Oauth redirect back to the route
$this->visit('/auth/facebook/callback')
// See the page that the user login into
->seePageIs('/');

注意：use 你班级顶部的社交名流包

使用 Laravel\Socialite\Facades\Socialite；

我遇到了同样的问题，但我能够使用上述技术解决它； @ceejayoz。我希望这会有所帮助。

Answer 3

这可能更难做到，但我相信它会使测试更具可读性。希望您能帮助我简化我将要描述的内容。

我的想法是存根 http 请求。考虑到 facebook，有两个：1）/oauth/access_token（获取访问令牌），2）/me（获取有关用户的数据）。

为此，我暂时将php 附加到mitmproxy 以创建vcr 夹具：

1. 告诉php 使用http 代理（将以下行添加到.env 文件中）：

   HTTP_PROXY=http://localhost:8080
   HTTPS_PROXY=http://localhost:8080
   

2. 告诉php代理的证书在哪里：将openssl.cafile = /etc/php/mitmproxy-ca-cert.pem添加到php.ini。或者curl.cainfo，就此而言。

3. 重启php-fpm。
4. 开始mitmproxy。
5. 让您的浏览器也通过mitmproxy 连接。

6. 使用 facebook 登录您正在开发的网站（此处没有 TDD）。

   按z in mitmproxy（C for mitmproxy f 命令（l for mitmproxy graph.facebook.com 过滤掉额外的请求。

   请注意，对于 twitter，您需要 league/oauth1-client 1.7 或更高版本。一个从guzzle/guzzle 切换到guzzlehttp/guzzle。否则您将无法登录。

7. 将数据从mimtproxy 复制到tests/fixtures/facebook。我使用了yaml 格式，如下所示：

   -
       request:
           method: GET
           url: https://graph.facebook.com/oauth/access_token?client_id=...&client_secret=...&code=...&redirect_uri=...
       response:
           status:
               http_version: '1.1'
               code: 200
               message: OK
           body: access_token=...&expires=...
   -
       request:
           method: GET
           url: https://graph.facebook.com/v2.5/me?access_token=...&appsecret_proof=...&fields=first_name,last_name,email,gender,verified
       response:
           status:
               http_version: '1.1'
               code: 200
               message: OK
           body: '{"first_name":"...","last_name":"...","email":"...","gender":"...","verified":true,"id":"..."}'
   

   如果你有mitmproxy >= 0.18，你可以使用命令E。或者，使用命令P。它将请求/响应复制到剪贴板。如果您希望mitmproxy 将它们保存到文件中，您可以使用DISPLAY= mitmproxy 运行它。

   我认为无法使用 php-vcr 的记录工具，因为我没有测试整个工作流程。

这样我就可以编写以下测试（是的，它们可以用点替换所有这些值，请随意复制）。

请注意，固定装置取决于 laravel/socialite 的版本。我遇到了 Facebook 的问题。在版本2.0.16laravel/socialite 开始做post requests 以获取访问令牌。脸书网址中还有api version。

这些装置适用于2.0.14。处理它的一种方法是在composer.json 文件的require-dev 部分中也有laravel/socialite 依赖项（具有严格的版本规范），以确保socialite 在开发环境中具有正确的版本（希望composer将忽略生产环境中require-dev 部分中的那个。）考虑到您在生产环境中执行composer install --no-dev。

注意。确保您有 php-vcr/phpunit-testlistener-vcr 必需，并且您的 phpunit.xml 中有以下行：

<listeners>
    <listener class="PHPUnit_Util_Log_VCR" file="vendor/php-vcr/phpunit-testlistener-vcr/PHPUnit/Util/Log/VCR.php"/>
</listeners>

还有一个问题是在运行测试时没有设置$_SERVER['HTTP_HOST']。我在这里谈论config/services.php 文件，即关于重定向网址。我是这样处理的：

 <?php

$app = include dirname(__FILE__) . '/app.php';

return [
    ...
    'facebook' => [
        ...
        'redirect' => (isset($_SERVER['HTTP_HOST']) ? 'http://' . $_SERVER['HTTP_HOST'] : $app['url']) . '/auth/facebook/callback',
    ],
];

不是特别漂亮，但我没找到更好的方法。我打算在那里使用config('app.url')，但它在配置文件中不起作用。

UPD 你可以去掉setUpBeforeClass 部分，方法是删除这个方法，运行测试，用vcr 记录的更新fixture 的request 部分。实际上，整个事情可能只用vcr 就可以完成（不是mitmproxy）。

Answer 4

我实际上创建了返回虚拟用户数据的 Fake 类，因为我有兴趣测试我的逻辑，而不是社交名流和供应商是否正常工作。

// This is the fake class that extends the original SocialiteManager
class SocialiteManager extends SocialiteSocialiteManager
{
    protected function createFacebookDriver()
    {
        return $this->buildProvider(
            FacebookProvider::class, // This class is a fake that returns dummy user in facebook's format
            $this->app->make('config')['services.facebook']
        );
    }

    protected function createGoogleDriver()
    {
        return $this->buildProvider(
            GoogleProvider::class, // This is a fake class that ereturns dummy user in google's format
            $this->app->make('config')['services.google']
        );
    }
}

下面是其中一个 Fake 提供者的样子：

class FacebookProvider extends SocialiteFacebookProvider
{
    protected function getUserByToken($token)
    {
        return [
            'id' => '123123123',
            'name' => 'John Doe',
            'email' => 'test@test.com',
            'avatar' => 'image.jpg',
        ];
    }
}

当然，在测试课中，我将原来的 SocialiteManager 替换为我的版本：

public function setUp(): void
    {
        parent::setUp();

        $this->app->singleton(Factory::class, function ($app) {
            return new SocialiteManager($app);
        });
    }

这对我来说很好用。无需嘲笑任何东西。
