I took the course PHPUnit for Beginners by Laravel Daily. It is suitable for total testing beginners and walks you through a simple CRUD application. Here are my takeaways in the format of question and answer. They are sorted by occurence in the course but you can use whatever you need for your application and testing — not everything is related to testing: It covers the case where there is no data $response = $this->put('/products/' . product->id, ['name' => 'Test']);$response->assertSessionHasErrors(['name']); Original: https://martinbetz.eu/article/phpunit-beginners-takeaways
