Introduction

Laravel is built with testing in mind. In fact, support for testing with PHPUnit is included out of the box and a phpunit.xml file is already set up for your application. The framework also ships with convenient helper methods that allow you to expressively test your applications.

By default, your application's tests directory contains two directories: Feature and Unit. Unit tests are tests that focus on a very small, isolated portion of your code. In fact, most unit tests probably focus on a single method. Tests within your "Unit" test directory do not boot your Laravel application and therefore are unable to access your application's database or other framework services.

Feature tests may test a larger portion of your code, including how several objects interact with each other or even a full HTTP request to a JSON endpoint. Generally, most of your tests should be feature tests. These types of tests provide the most confidence that your system as a whole is functioning as intended.

An ExampleTest.php file is provided in both the Feature and Unit test directories. After installing a new Laravel application, execute the vendor/bin/phpunit or php artisan test commands to run your tests.

Environment

When running tests via vendor/bin/phpunit, Laravel will automatically set the configuration environment to testing because of the environment variables defined in the phpunit.xml file. Laravel also automatically configures the session and cache to the array driver while testing, meaning no session or cache data will be persisted while testing.

You are free to define other testing environment configuration values as necessary. The testing environment variables may be configured in your application's phpunit.xml file, but make sure to clear your configuration cache using the config:clear Artisan command before running your tests!

The .env.testing Environment File

In addition, you may create a .env.testing file in the root of your project. This file will be used instead of the .env file when running PHPUnit tests or executing Artisan commands with the --env=testing option.

Creating & Running Tests

To create a new test case, use the make:test Artisan command. By default, tests will be placed in the tests/Feature directory:

php artisan make:test UserTest

If you would like to create a test within the tests/Unit directory, you may use the --unit option when executing the make:test command:

php artisan make:test UserTest --unit

{tip} Test stubs may be customized using stub publishing

Once the test has been generated, you may define test methods as you normally would using PHPUnit. To run your tests, execute the vendor/bin/phpunit or php artisan test command from your terminal:

<?php

namespace Tests\Unit;

use PHPUnit\Framework\TestCase;

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

{note} If you define your own setUp / tearDown methods within a test class, be sure to call the respective parent::setUp() / parent::tearDown() methods on the parent class.

Artisan Test Runner

In addition to the phpunit command, you may use the test Artisan command to run your tests. The Artisan test runner provides verbose test reports in order to ease development and debugging:

php artisan test

Any arguments that can be passed to the phpunit command may also be passed to the Artisan test command:

php artisan test --testsuite=Feature --stop-on-failure
