以下は接続テスト用、phpunitの動作チェック用のファイルです

index.php

<?php
phpinfo();

sample.php

<?php
declare(strict_types=1);
namespace App;

class Sample
{
    public function hello() {
        return "Hello World";
    }
}

tests/sampleTest.php

<?php

use PHPUnit\Framework\TestCase;
use App\Sample;

class SampleTest extends TestCase
{
    public function testReturnHello()
    {
        $sample = new Sample();
        $result = $sample->hello();

        $this->assertEquals("Hello World", $result);
    }
}

コンテナを起動する

$ docker-compose up -d

ブラウザで localhost に接続

ブラウザで localhost:8080 に接続

PHPUnit をインストールする

$ docker-compose exec php composer update

テストを実行する

$ docker-compose exec php composer test -- html/tests
