README

A fake PayPal API server for testing Laravel applications. It replaces the real puntodev/paypal client with a mock implementation that simulates the full checkout flow without hitting the PayPal API.

Installation

composer require --dev puntodev/paypal-fake

Activation

Set the environment variable in your .env or phpunit.xml:

PAYPAL_USE_FAKE=true

The service provider auto-registers and swaps the PayPal binding in the container with PayPalFake.

How It Works

The library has four main components:

PayPalFake

Extends PayPal and manages global test state. Stores orders in a file-based cache, records method calls for assertions, and provides a reset() method to clean up between tests.

PayPalFakeApi

Extends PayPalApi with mock implementations:

createOrder(array $order) — Generates a fake order ID, stores it in cache, and returns the expected response structure.
findOrderById(string $id) — Retrieves a stored order from cache.
captureOrder(string $orderId) — Simulates payment capture. Throws a RequestException if the order was marked as declined.
verifyIpn(string $querystring) — Always returns 'VERIFIED'.

FakeCheckoutController

Exposes HTTP routes that simulate PayPal's checkout UI:

Method	Route	Description
GET	`/paypal-fake/checkout/{orderId}`	Displays a styled checkout page with Approve, Decline, and Cancel buttons
POST	`/paypal-fake/checkout/{orderId}/approve`	Simulates approval and posts a webhook to your app
POST	`/paypal-fake/checkout/{orderId}/decline`	Marks the order as declined
GET	`/paypal-fake/checkout/{orderId}/cancel`	Redirects to the order's cancel URL

PayPalFakeServiceProvider

When PAYPAL_USE_FAKE is true, it binds PayPalFake as a singleton in place of PayPal, registers the checkout routes, and loads the Blade views.

Checkout Flow

Your test creates an order via PayPalFakeApi::createOrder()
        ↓
Order is stored in file cache (300s TTL)
        ↓
Test or browser approves the order
        ↓
Webhook POSTed to /paypal/webhook/{providerId}
        ↓
Test captures payment via PayPalFakeApi::captureOrder()
        ↓
Assertions via PayPalFake::getCalls()

Usage

Automated Tests

use Puntodev\PaymentsFake\PayPalFake;
use Puntodev\Payments\PayPal;
use Puntodev\Payments\OrderBuilder;

// Get the fake client
$client = app(PayPal::class)->defaultClient();

// Create an order
$order = (new OrderBuilder())
    ->currency('USD')
    ->amount(25.00)
    ->make();

$created = $client->createOrder($order);

// Capture the payment
$captured = $client->captureOrder($created['id']);

// Assert calls were made
$calls = PayPalFake::getCalls('createOrder');
$this->assertCount(1, $calls);

// Clean up
PayPalFake::reset();

Manual Browser Testing

Start your Laravel app with PAYPAL_USE_FAKE=true and navigate to /paypal-fake/checkout/{orderId} after creating an order. The checkout page lets you click Approve, Decline, or Cancel to test the full flow, including webhooks hitting your application.
