To create tests in Laravel, use the Artisan command php artisan make:test, which generates feature or unit tests. 1. Run php artisan make:test UserTest to create a feature test in tests/Feature. 2. Use php artisan make:test Auth/UserTest to place tests in subdirectories. 3. Add --unit for unit tests in tests/Unit when testing internal logic without HTTP requests. 4. Include --pest to generate Pest-style tests for concise syntax. 5. Write effective tests by using descriptive method names, Laravel helpers like get() and post(), and traits like RefreshDatabase, ensuring proper organization and maintainability as your app grows.

Creating a new test in Laravel is straightforward thanks to the built-in Artisan command make:test. This command helps you scaffold test classes quickly, whether you're writing feature tests or unit tests.

Here's how to use it effectively and what you should know when creating tests in Laravel.

Basic Usage of php artisan make:test

To create a new test, run this Artisan command:

php artisan make:test UserTest

This will generate a new test file named UserTest.php inside the tests/Feature directory by default. The generated class includes a basic test method to get you started.

If you want to place the test in a subdirectory, like Auth, you can do:

php artisan make:test Auth/UserTest

Laravel will automatically create the Auth folder inside Feature and put the test file there.

Creating Unit Tests Instead of Feature Tests

By default, make:test creates a feature test, which is intended for testing HTTP routes and full interactions. If you need a unit test instead (for testing individual classes or methods), use the --unit flag:

php artisan make:test UserTest --unit

This will place the test in the tests/Unit directory and extend the base unit test case (PHPUnit\Framework\TestCase) instead of Laravel’s feature test case.

You might want to use unit tests when:

• You're testing internal logic that doesn't involve HTTP requests
• You want faster execution without booting the entire framework

Choosing Between Pest and PHPUnit

If your Laravel project uses Pest (a lightweight testing framework for PHP), you can tell Artisan to generate Pest-style tests using the --pest option:

php artisan make:test UserTest --pest

This creates a test file with a .php extension but uses Pest syntax, which is more concise than traditional PHPUnit style.

If you don’t specify --pest, Laravel will generate a standard PHPUnit-style test class.

Tips for Writing Effective Tests

When you start writing tests, keep these points in mind:

• Always give your test methods descriptive names. For example: test_user_can_login_with_valid_credentials()
• Use Laravel’s test helpers like get(), post(), assertStatus(), etc., in feature tests
• For database-related tests, consider using the RefreshDatabase trait to reset state between tests
• Don’t forget to import any models or classes you’re testing at the top of the file

Example:

use Illuminate\Foundation\Testing\RefreshDatabase;

class UserTest extends TestCase
{
    use RefreshDatabase;

    /** @test */
    public function user_can_register()
    {
        $response = $this->post('/register', [
            'name' => 'John Doe',
            'email' => 'john@example.com',
            'password' => 'password123',
        ]);

        $response->assertRedirect('/dashboard');
        $this->assertDatabaseHas('users', ['email' => 'john@example.com']);
    }
}

That's basically how you create and work with tests in Laravel using php artisan make:test. It’s not complicated, but getting into good habits early—like organizing tests properly and choosing the right test type—will help you maintain quality as your app grows.
