💼 Career

Writing feature tests is a key skill for Laravel developers. It helps maintain code quality and confidence when making changes.

1

Create the feature test class

Create a feature test class named HomePageTest inside the tests/Feature directory. Use the namespace Tests\Feature and extend the Tests\TestCase class.

Laravel

<?php

namespace Tests\Feature;

use Tests\TestCase;

// Your code here

Need a hint?

Use php artisan make:test HomePageTest to generate the test class automatically.

2

Add the test method

Inside the HomePageTest class, add a public method named test_homepage_loads_successfully that will hold the test logic.

Laravel

<?php

namespace Tests\Feature;

use Tests\TestCase;

class HomePageTest extends TestCase
{
    // Your code here
}

Need a hint?

Test methods should start with test_ and be public.

3

Request the homepage and check status

Inside the test_homepage_loads_successfully method, use $this->get('/') to request the homepage. Store the response in a variable named $response. Then assert that the response status is 200 using assertStatus(200).

Laravel

<?php

namespace Tests\Feature;

use Tests\TestCase;

class HomePageTest extends TestCase
{
    public function test_homepage_loads_successfully()
    {
        // Your code here
    }
}

Need a hint?

Use $response = $this->get('/') to get the homepage response.

4

Assert the homepage contains welcome text

Add an assertion to the test_homepage_loads_successfully method that checks if the response contains the text 'Welcome to the Blog' using assertSee('Welcome to the Blog').

Laravel

get('/');
        $response->assertStatus(200);
        // Your code here
    }
}

Need a hint?

Use assertSee to check if the response contains specific text.
