Unit Test Example

<?php

namespace Tests\Blog\Post\Application\Create;

use PHPUnit\Framework\TestCase;

final class CreatePostHandlerTest extends TestCase
{
    public function testCreatesPost(): void
    {
        $repository = $this->createMock(PostRepositoryInterface::class);
        $repository->expects($this->once())->method('save');

<?php

namespace Tests\Blog\Post\Application\Create;

use Symfony\Bundle\FrameworkBundle\Test\KernelTestCase;

final class CreatePostIntegrationTest extends KernelTestCase
{
    public function testCreatesPostInDatabase(): void
    {
        self::bootKernel();

        $commandBus = static::getContainer()->get(MessageBusInterface::class);
        $command = new CreatePostCommand('Title', 'Content');

        $commandBus->dispatch($command);

        $repository = static::getContainer()->get(PostRepositoryInterface::class);
        $posts = $repository->findAll();

        $this->assertCount(1, $posts);
