Using a Test Database

Hey mehdi

That's because the tests have a special setup, when you call self::bootKernel() on any test method, the kernel by default will choose "test" environment, you can change it by passing as first argument an array with the key "APP_ENV", or by setting up an environment variable

Cheers!

Hey Vladimir Z.

In Symfony4 you only have one "app.php" file, and in reality, it's not called "app.php" anymore, instead it's called "index.php". So, you don't have to create another file for your testing environment, you only have to set the APP_ENV global variable to "test". So, if you are using PHPUnit, you will have to declare that variable in your phpunit.xml:

<php>
        ...
        <env name="APP_ENV" value="test" />
</php>

Cheers!

MolloKhan if my PHPUnit test cases use Guzzle to issue requests to API endpoints, will it automatically recognize these Guzzle requests as coming from the PHPUnit tests?

Good question. I'm not totally sure about it, you can give it a try. If it doesn't work let me know, and probably you may want to use the "BrowserKit" from Symfony meanwhile we find a proper solution to this situation

MolloKhan I see that the Symfony Client has an 'enviroment' parameter that can be used (haven't tested it yet). I was wondering whether Guzzle has something like that. MolloKhan do you have an idea here?

Actually, there is nothing wrong using Symfony's client instead of Guzzle in your tests, it's easier to use and it does not require any setup

Hey Shaun T.

That config only works when working on PHPUnit, you need to specify your test database in your test doctrine.yaml file.

// config/packages/test/doctrine.yaml
doctrine:
    dbal:
        url: '%env(resolve:DATABASE_URL)%_test'

Cheers!

Thanks MolloKhan :)

Shaun T. I have come across a problem related to this.

In my TokenControllerTest I can create a user in the test database, but in TokenController findOneBy is querying the Development database!

Do you know how I can resolve this please?

Hmm, how are you executing that controller's action? You have to assure that your kernel is booting on test environment, like "PHPUnit KernelCase class" does when you run self::bootKernel();

Thanks MolloKhan, you were right, it was the Kernel :)

Hey Shaun,

Yes, we can! Actually, there's Symfony Demo project that's on Symfony 4 now and has PHPUnit configured, you can look at the code here: https://github.com/symfony/...

Cheers!

Thanks victor :)

I have had a look at the Symfony demo and it seems to have it's own client rather than using Guzzle.

How can the setUpBeforeClass() method be modified so that it uses the Symfony client rather than Guzzle?

public static function setUpBeforeClass()
{
self::$staticClient = new Client([
'base_url' => 'http://localhost:8000',
'defaults' => [
'exceptions' => false
]
]);
self::$history = new History();
self::$staticClient->getEmitter()
->attach(self::$history);

self::bootKernel();
}

Hey Shaun,

If you want to use Symfony's client instead of Guzzle, just do as Symfony Demo does, it uses exactly Symfony client :) i.e. you just need to extend WebTestCase and then with static::createClient(); you will get the client.

Cheers!

Hey I just had a similar problem although the response was not empty Guzzle was kind of ignoring the "/app_test.php" part of the base url. The problem was that in my setup (Symfony 3, Guzzle ^6.2) Guzzle overrides the path if the request uses an absolute path like "/api/...". Using "api/..." instead solved the problem for me.

Since it worked in the video I suppose this might be an issue with the later versions.

You're absolutely correct about the absolute paths (and I *do* think this was something that was added in some more recent versions of Guzzle). To get around it, we use a middleware that adds the app_test.php even when the URL starts with a slash. It's an annoying little thing to need to add, but it works pretty well. Here's the Guzzle 6 version for those who are curious: https://gist.github.com/wea...

Cheers!

This just saved my day. :D Thank You
