How to Test Laravel APIs

Laravel is a powerful PHP web application framework that allows developers to build robust and scalable web applications. With its built-in features and libraries, Laravel is becoming increasingly popular among web developers. Laravel's API development capabilities allow developers to build RESTful APIs quickly and easily.

Testing Laravel APIs is essential to ensure that they are functioning correctly and efficiently. In this article, we will discuss how to test Laravel APIs.

Install PHPUnit

PHPUnit is a testing framework for PHP that allows developers to write and run tests for their PHP code. Laravel comes with PHPUnit pre-installed, so you don't have to install it manually. However, if you're working with an older version of Laravel or want to install PHPUnit manually, you can do so using Composer.

To install PHPUnit using Composer, run the following command:

composer require --dev phpunit/phpunit

Create a Test Class

To test Laravel APIs, you need to create a test class. Test classes in Laravel extend the TestCase class, which provides several methods for testing your API.

To create a test class, run the following command:

php artisan make:test MyApiTest

This command will create a new file named MyApiTest.php in the tests/Feature directory. Open this file and update the class as follows:


namespace Tests\Feature;

use Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Foundation\Testing\WithFaker;
use Tests\TestCase;

class MyApiTest extends TestCase
     * A basic test example.
     * @return void
    public function testExample()

Write Test Methods

Now that you have created a test class, you can write test methods to test your API. Laravel provides several methods for testing APIs, including get, post, put, patch, and delete.

Here's an example of a test method that tests a GET API:

public function testGetApi()
    $response = $this->get('/api/users');
        'data' => [
            '*' => [

This method sends a GET request to the /api/users endpoint and asserts that the response status code is 200. It also asserts that the JSON response has the expected structure.

Run Tests

To run your tests, use the following command:

php artisan test

This command will run all the tests in your tests directory. You can also run a specific test class or method by passing the class or method name as an argument:

php artisan test --filter MyApiTest
php artisan test --filter testGetApi


Testing Laravel APIs is crucial to ensure that they are functioning correctly and efficiently. In this article, we discussed how to test Laravel APIs using PHPUnit. We created a test class, wrote test methods, and ran the tests using the php artisan test command. By following these steps, you can ensure that your Laravel APIs are reliable, secure, and scalable.
