README

一个用于在您的 Symfony 测试中将容器中的服务填充到测试类属性的 trait。

如何使用

• 在任何扩展 Symfony\Bundle\FrameworkBundle\Test\KernelTestCase 的测试中使用 use TestClassServicePropertyInjectorTrait
• 在您的 setUp() 方法中调用 $this->injectContainerServicesIntoClassProperties()

它的作用

将所有私有和受保护的属性设置为它们各自的服务。要设置属性，它必须

• 是 private 或 protected
• 类型提示为非标量类型
• 具有与容器中服务匹配的类型提示

使用示例

use App\Services\FooService;
use App\Services\BarService;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
use webignition\SymfonyTestServiceInjectorTrait\TestClassServicePropertyInjectorTrait;

class AcmeControllerTest extends WebTestCase
{
    use TestClassServicePropertyInjectorTrait;

    private FooService $fooService;
    private BarService $barService;
    
    protected function setUp(): void
    {
        parent::setUp();
        $this->injectContainerServicesIntoClassProperties();
    }
    
    public function testUsingFooService(): void
    {
        $foo = $this->fooService->createFoo();

        // ... carry out tests that depend on FooService creating $foo
    }
    
    public function testUsingBarService(): void
    {
        $bar = $this->barService->createBar();

        // ... carry out tests that depend on BarService creating $bar
    }
}

前后比较

之前

use App\Services\ServiceA;
use App\Services\ServiceB;
use App\Services\ServiceC;
use App\Services\ServiceD;
use App\Services\ServiceE;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class AcmeControllerTest extends WebTestCase
{
    private ServiceA $serviceA;
    private ServiceB $serviceB;
    private ServiceC $serviceC;
    private ServiceD $serviceD;
    private ServiceE $serviceE;
    
    protected function setUp(): void
    {
        parent::setUp();
        
        $serviceA = self::$container->get(ServiceA::class);
        if ($serviceA instanceof ServiceA) {
            $this->serviceA = $serviceA;
        }

        $serviceB = self::$container->get(ServiceB::class);
        if ($serviceB instanceof ServiceB) {
            $this->$serviceB = $serviceB;
        }

        $serviceC = self::$container->get(ServiceC::class);
        if ($serviceC instanceof ServiceC) {
            $this->$serviceC = $serviceC;
        }

        $serviceD = self::$container->get(ServiceD::class);
        if ($serviceD instanceof ServiceD) {
            $this->$serviceD = $serviceD;
        }

        $serviceE = self::$container->get(ServiceE::class);
        if ($serviceE instanceof ServiceE) {
            $this->$serviceE = $serviceE;
        }
    }
}

之后

use App\Services\ServiceA;
use App\Services\ServiceB;
use App\Services\ServiceC;
use App\Services\ServiceD;
use App\Services\ServiceE;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
use webignition\SymfonyTestServiceInjectorTrait\TestClassServicePropertyInjectorTrait;

class AcmeControllerTest extends WebTestCase
{
    use TestClassServicePropertyInjectorTrait;

    private ServiceA $serviceA;
    private ServiceB $serviceB;
    private ServiceC $serviceC;
    private ServiceD $serviceD;
    private ServiceE $serviceE;
    
    protected function setUp(): void
    {
        parent::setUp();
        $this->injectContainerServicesIntoClassProperties();
    }
}
