‘Class Tests\TestCase not found’というエラーが出た。

autoloadが効いていないっぽい？

環境

• Mac
• Docker

app/tests/ExampleTest.php

<?php

use Illuminate\Foundation\Testing\WithoutMiddleware;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\DatabaseTransactions;

class ExampleTest extends TestCase
{
    /**
     * A basic functional test example.
     *
     * @return void
     */
    public function testBasicExample()
    {
        $this->assertTrue(true);
    }
}

vendor/composer/autoload_classmap.php

<?php

// autoload_classmap.php @generated by Composer

$vendorDir = dirname(dirname(__FILE__));
$baseDir = dirname($vendorDir);

return array(

・・・

    'TestCase' => $baseDir . '/tests/TestCase.php',
    'Text_Template' => $vendorDir . '/phpunit/php-text-template/src/Template.php',
    'TestCase' => $baseDir . '/app/tests/TestCase.php' ←●追加
);

これが必要なのかはわからないががが。消えるしな。

PHPが動いているコンテナに入る

$ docker exec -it web bash

# composer dump-autoload
