In PHP e-commerce, how do I write integration tests?

Integration tests in a PHP e-commerce application are essential for ensuring that various components work together as expected. These tests validate the interactions between different parts of the application, such as the database, payment gateways, and user authentication systems. By writing integration tests, you can catch issues early in the development process and maintain the reliability of your e-commerce platform.

Example of an Integration Test in PHP


        <?php
        use PHPUnit\Framework\TestCase;

        class EcommerceIntegrationTest extends TestCase {
            public function testCheckoutProcess() {
                // Simulate user login
                $user = $this->createUser();
                $this->loginUser($user);

                // Simulate adding items to the cart
                $item = $this->createProduct();
                $this->addItemToCart($item);

                // Perform checkout
                $response = $this->checkout();
                
                // Assertions
                $this->assertEquals(200, $response->getStatusCode());
                $this->assertDatabaseHas('orders', [
                    'user_id' => $user->id,
                    'product_id' => $item->id,
                ]);
            }

            protected function createUser() {
                // Logic to create a user
            }

            protected function loginUser($user) {
                // Logic to log in a user
            }

            protected function createProduct() {
                // Logic to create a product
            }

            protected function addItemToCart($item) {
                // Logic to add item to the cart
            }

            protected function checkout() {
                // Logic for checkout process
            }
        }
        ?>
