How to Test Laravel Socialite

Question

I have an application that makes use of socialite, I want to create test for Github authentication, So I used Socialite Facade to mock call to the Socialite driver

Answer 1

I've actually created Fake classes that return a dummy user data because I'm interested in testing my logic, not whether Socialite, nor the vendor work properly.

// 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']
        );
    }
}

And here is how one of the Fake providers look like:

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

And of course in the test class, I replace the original SocialiteManager with my version:

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

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

This works pretty fine to me. No need to mock anything.

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('/');

Note: use the socialite package at the top of your class

use Laravel\Socialite\Facades\Socialite;

I had the same problem, but I was able to solve it using the technique above; @ceejayoz. I hope this helps.

Answer 3

This may be harder to do, but I believe it makes for more readable tests. Hopefully you'll help me simplify what I'm about to describe.

My idea is to stub http requests. Considering facebook, there are two of them: 1) /oauth/access_token (to get access token), 2) /me (to get data about the user).

For that I temporarily attached php to mitmproxy to create vcr fixture:

1. Tell php to use http proxy (add the following lines to the .env file):

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

2. Tell php where proxy's certificate is: add openssl.cafile = /etc/php/mitmproxy-ca-cert.pem to php.ini. Or curl.cainfo, for that matter.

3. Restart php-fpm.
4. Start mitmproxy.
5. Make your browser connect through mitmproxy as well.

6. Log in to the site you're developing using facebook (no TDD here).

   Press z in mitmproxy (C for mitmproxy < 0.18) to clear request (flow) list before redirecting to facebook if need be. Or alternatively, use f command (l for mitmproxy < 0.18) with graph.facebook.com to filter out extra requests.

   Do note, that for twitter you'll need league/oauth1-client 1.7 or newer. The one switched from guzzle/guzzle to guzzlehttp/guzzle. Or else you'll be unable to log in.

7. Copy data from mimtproxy to tests/fixtures/facebook. I used yaml format and here's what it looks like:

   -
       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":"..."}'
   

   For that you can use command E if you've got mitmproxy >= 0.18. Alternatively, use command P. It copies request/response to clipboard. If you want mitmproxy to save them right to file, you can run it with DISPLAY= mitmproxy.

   I see no way to use php-vcr's recording facilities, since I'm not testing the whole workflow.

With that I was able to write the following tests (and yes, they are fine with all those values replaced by dots, feel free to copy as is).

Do note though, fixtures depend on laravel/socialite's version. I had an issue with facebook. In version 2.0.16 laravel/socialite started doing post requests to get access token. Also there's api version in facebook urls.

These fixtures are for 2.0.14. One way to deal with it is to have laravel/socialite dependency in require-dev section of composer.json file as well (with strict version specification) to ensure that socialite is of proper version in development environment (Hopefully, composer will ignore the one in require-dev section in production environment.) Considering you do composer install --no-dev in production environment.

Note. Make sure you have php-vcr/phpunit-testlistener-vcr required, and that you have the following line in your phpunit.xml:

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

There also was an issue with $_SERVER['HTTP_HOST'] not being set, when running tests. I'm talking about config/services.php file here, namely about redirect url. I handled it like so:

 <?php

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

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

Not particularly beautiful, but I failed to find a better way. I was going to use config('app.url') there, but it doesn't work in config files.

UPD You can get rid of setUpBeforeClass part by removing this method, running tests, and updating request part of fixtures with what vcr records. Actually, the whole thing might be done with vcr alone (no mitmproxy).

Answer 4

Well, both answers were great, but they have lots of codes that are not required, and I was able to infer my answer from them.

This is all I needed to do.

Firstly mock the Socialite User type

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

Second, set the expected values for its method calls

$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');

Thirdly, you need to mock the provider/user call

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

Then lastly you write your assertions

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