Installation

1. Add dependency with composer

composer require --dev vladdnepr/graphql-test

If you are using Symfony you will have to install "symfony/browser-kit".

How to use

Depending on your framework, extend the correct TestCase:

use VladDnepr\GraphQLTest\Bridge\Symfony\TestCase;

Everything you see in the next snippets is the same for all Test Cases.

In your tests you now have 2 additional helper methods:

public function query(QueryInterface $query, array $files = [], array $headers = []);
public function mutation(MutationInterface $mutation, array $files = [], array $headers = [])

By default, endpoint is /graphql, you can overwrite this by changing variable in your tests:

use VladDnepr\GraphQLTest\Bridge\Symfony\TestCase;

class UserTest extends TestCase
{
    public static $endpoint = '/';
}

There is a helper method that allows you to preset headers:

use VladDnepr\GraphQLTest\Bridge\Symfony\TestCase;

class SettingsTest extends TestCase
{
    protected function setUp()
    {
        $this->setDefaultHeaders([
            'Content-Type' => 'application/json',
        ]);
    }
}

Examples

Query

use VladDnepr\GraphQLTest\Bridge\Symfony\TestCase;
use VladDnepr\GraphQLTest\Operation\Query;

class SettingsQueryTest extends TestCase
{
    public static $endpoint = '/';

    protected function setUp()
    {
        $this->setDefaultHeaders([
            'Content-Type' => 'application/json',
        ]);
    }

    public function testSettingsQuery(): void
    {
        $query = $this->query(
            new Query(
                'settings',
                [],
                [
                    'name',
                    'isEnabled',
                ],
            )
        );
        
        //Fetch response and do asserts
    }
}

VladDnepr\GraphQLTest\Operation\Query construct accepts 3 arguments:

• name of query (mandatory)
• parameters (optional)
• fields (optional)

Mutation

use VladDnepr\GraphQLTest\Bridge\Symfony\TestCase;
use VladDnepr\GraphQLTest\Operation\Mutation;

class SettingsMutationTest extends TestCase
{
    public static $endpoint = '/';

    protected function setUp()
    {
        $this->setDefaultHeaders([
            'Content-Type' => 'application/json',
        ]);
    }

    public function testSettingsMutation(): void
    {
        $mutation = $this->mutation(
            new Mutation(
                'createSettings',
                [
                    'name' => 'hide-menu-bar',
                    'isEnabled' => true,
                ],
                [
                    'name',
                    'isEnabled',
                ],
            )
        );
        
        //Fetch response and do asserts
    }
}

VladDnepr\GraphQLTest\Operation\Mutation construct accepts 3 arguments:

• name of mutation (mandatory)
• parameters (optional)
• fields (optional)

If you have a Enum, Boolean or Array as an argument you can pass it as following:

use VladDnepr\GraphQLTest\Bridge\Symfony\TestCase;
use VladDnepr\GraphQLTest\Operation\Mutation;
use VladDnepr\GraphQLTest\Type\EnumType;
use VladDnepr\GraphQLTest\Type\BooleanType;
use VladDnepr\GraphQLTest\Type\ArrayType;

class UserMutationTest extends TestCase
{
    //...
    public function testUserMutation(): void
    {
        $mutation = $this->mutation(
            new Mutation(
                'createUser',
                [
                    
                    'username' => 'kunicmarko20',
                    'salutation' => new EnumType('Mr'),
                    'enabled' => new BooleanType(true),
                    'roles' => new ArrayType(['ROLE_ADMIN', 'ROLE_TEST']),
                    //..
                ],
                [
                    'username',
                    'salutation',
                ],
            )
        );
        
        //Fetch response and do asserts
    }
}

Also, if you need a custom type you can always extend VladDnepr\GraphQLTest\Type\TypeInterface and use your own Type instead.
