How write tests. Can you look at my first testCase?

<?php

Tester\Environment::setup();

$configurator = new Nette\Configurator;

$configurator->createRobotLoader()
	->addDirectory(__DIR__ . '/../app')
	->register();

$configurator->addConfig(__DIR__ . '/../app/config/config.neon');
$configurator->addConfig(__DIR__ . '/../app/config/config.local.neon');

return $configurator->createContainer();
