Pest Testing in Bagisto

When to Apply

Activate this skill when:

• Creating new tests (unit or feature)
• Modifying existing tests
• Debugging test failures
• Working with datasets, mocking, or test organization
• Writing architecture tests
• Testing Bagisto packages (Admin, Shop, Core, etc.)

Bagisto Testing Structure

Pest.php Configuration

Bagisto uses tests/Pest.php to register test cases for each package:

<?php

uses(Webkul\Admin\Tests\AdminTestCase::class)->in('../packages/Webkul/Admin/tests');
uses(Webkul\Core\Tests\CoreTestCase::class)->in('../packages/Webkul/Core/tests');
uses(Webkul\Customer\Tests\CustomerTestCase::class)->in('../packages/Webkul/Customer/tests');
uses(Webkul\DataGrid\Tests\DataGridTestCase::class)->in('../packages/Webkul/DataGrid/tests');
uses(Webkul\EUWithdrawal\Tests\EUWithdrawalTestCase::class)->in('../packages/Webkul/EUWithdrawal/tests');
uses(Webkul\Installer\Tests\InstallerTestCase::class)->in('../packages/Webkul/Installer/tests');
uses(Webkul\Payment\Tests\PaymentTestCase::class)->in('../packages/Webkul/Payment/tests');
uses(Webkul\PayU\Tests\PayUTestCase::class)->in('../packages/Webkul/PayU/tests');
uses(Webkul\Razorpay\Tests\RazorpayTestCase::class)->in('../packages/Webkul/Razorpay/tests');
uses(Webkul\Shop\Tests\ShopTestCase::class)->in('../packages/Webkul/Shop/tests');
uses(Webkul\Stripe\Tests\StripeTestCase::class)->in('../packages/Webkul/Stripe/tests');

Test Case Structure

Each package has its own test case that extends Tests\TestCase:

// packages/Webkul/Shop/tests/ShopTestCase.php
<?php

namespace Webkul\Shop\Tests;

use Tests\TestCase;
use Webkul\Core\Tests\Concerns\CoreAssertions;
use Webkul\Shop\Tests\Concerns\ShopTestBench;

class ShopTestCase extends TestCase
{
    use CoreAssertions, ShopTestBench;
}

Composer.json Autoload Configuration

Production Autoload

Package namespaces are registered in root composer.json:

"autoload": {
    "psr-4": {
        "Webkul\\Admin\\": "packages/Webkul/Admin/src",
        "Webkul\\Shop\\": "packages/Webkul/Shop/src",
        "Webkul\\Core\\": "packages/Webkul/Core/src",
        ...
    }
}

Development Autoload

Test namespaces are registered in autoload-dev:

"autoload-dev": {
    "psr-4": {
        "Tests\\": "tests/",
        "Webkul\\Admin\\Tests\\": "packages/Webkul/Admin/tests",
        "Webkul\\Core\\Tests\\": "packages/Webkul/Core/tests",
        "Webkul\\DataGrid\\Tests\\": "packages/Webkul/DataGrid/tests",
        "Webkul\\Installer\\Tests\\": "packages/Webkul/Installer/tests",
        "Webkul\\Shop\\Tests\\": "packages/Webkul/Shop/tests"
    }
}

Running Tests

Run All Tests

php artisan test --compact

Run Specific Test Suite

php artisan test --testsuite="Shop Feature Test"
php artisan test --testsuite="Admin Feature Test"
php artisan test --testsuite="Core Unit Test"

Run Specific Test File

php artisan test --compact packages/Webkul/Shop/tests/Feature/Checkout/CheckoutTest.php

Run Test with Filter

php artisan test --compact --filter=testName

Run Tests for Specific Package

# Shop tests
php artisan test --compact packages/Webkul/Shop/tests/

# Admin tests
php artisan test --compact packages/Webkul/Admin/tests/

Creating New Tests

Create Feature Test

php artisan make:test --pest packages/Webkul/Shop/tests/Feature/Checkout/MyNewTest

Create Unit Test

php artisan make:test --pest --unit packages/Webkul/Core/tests/Unit/MyNewTest

Basic Test Structure

<?php

namespace Webkul\Shop\Tests\Feature\Checkout;

use Webkul\Shop\Tests\ShopTestCase;

it('should pass basic test', function () {
    expect(true)->toBeTrue();
});

it('should return successful response', function () {
    $response = $this->getJson('/api/categories');

    $response->assertStatus(200);
});

Assertions

Use specific assertions (assertSuccessful(), assertNotFound()) instead of assertStatus():

Use	Instead of
assertSuccessful()	assertStatus(200)
assertNotFound()	assertStatus(404)
assertForbidden()	assertStatus(403)

Mocking

Import mock function before use:

use function Pest\Laravel\mock;

Datasets

Use datasets for repetitive tests:

it('has valid emails', function (string $email) {
    expect($email)->not->toBeEmpty();
})->with([
    'james' => '[e-mail]',
    'john'  => '[e-mail]',
]);

Architecture Testing

Pest 3 includes architecture testing to enforce code conventions:

arch('controllers')
    ->expect('Webkul\Admin\Http\Controllers')
    ->toExtendNothing()
    ->toHaveSuffix('Controller');

arch('models')
    ->expect('Webkul\Core\Models')
    ->toExtend('Illuminate\Database\Eloquent\Model');

arch('no debugging')
    ->expect(['dd', 'dump', 'ray'])
    ->not->toBeUsed();

Adding Tests to a New Package

If you add tests to a new package, you need to:

1. Register in Pest.php: Add the test case binding:

uses(Webkul\NewPackage\Tests\NewPackageTestCase::class)->in('../packages/Webkul/NewPackage/tests');

2. Register in composer.json (autoload-dev):

"autoload-dev": {
    "psr-4": {
        "Webkul\\NewPackage\\Tests\\": "packages/Webkul/NewPackage/tests"
    }
}

3. Register in phpunit.xml: Add a new testsuite:

<testsuite name="New Package Test">
    <directory suffix="Test.php">packages/Webkul/NewPackage/tests</directory>
</testsuite>

4. Run composer dump-autoload:

composer dump-autoload

Common Pitfalls

• Not importing use function Pest\Laravel\mock; before using mock
• Using assertStatus(200) instead of assertSuccessful()
• Forgetting to run composer dump-autoload after adding test namespace
• Not registering test case in tests/Pest.php
• Not adding testsuite to phpunit.xml for package-specific testing
• Deleting tests without approval
• Forgetting to register test namespace in composer.json autoload-dev

Testing Best Practices

• Test happy paths, failure paths, and edge cases.
• Use factories for model creation in tests.
• Follow existing test patterns in the package.
• Use $this->faker or fake() for generating test data.
• Keep tests focused and independent.
