In PHP payment processing, how do I write integration tests?

In PHP payment processing, integration tests are essential to ensure that your application correctly interacts with payment gateways and handles various scenarios like success, failure, and edge cases. Below is a simple example of how you can write integration tests using PHPUnit for a PHP application that processes payments.

paymentProcessor = new PaymentProcessor(); } public function testPaymentSuccess() { // Mock successful payment response $response = $this->paymentProcessor->processPayment(100, 'valid_card_info'); $this->assertTrue($response->isSuccess()); $this->assertEquals('Payment processed successfully', $response->getMessage()); } public function testPaymentFailure() { // Mock failed payment response $response = $this->paymentProcessor->processPayment(100, 'invalid_card_info'); $this->assertFalse($response->isSuccess()); $this->assertEquals('Payment processing failed', $response->getMessage()); } } ?>
