If you are a business that sells goods or services, a payment checkout page for all your customers, registered or guests, is mandatory. It is one component that every consumer will encounter when buying via your website. And that is why you need to validate your payment process page through an exhaustive checkout test. Here’s a blog to get you started.

What is a Checkout Test?

A checkout test refers to verifying your payment process when a user tries to buy products or services on your website. The goal of this testing is to ensure that the customer does not experience any difficulty in proceeding to checkout and making the payment to complete the purchase. Some of the reasons why users abandon the checkout process are:

  • Confusing/long checkout page
  • High loading time or instances of page crashing
  • Any of the submit/next/proceed options for the purchase are not working properly

You need to test all this and more in checkout testing. Let’s discuss the different testing types you need to perform for the checkout test.

Types of Testing to Perform on the Checkout Test

There are a number of tests that you need to perform on the checkout page to ensure that none of your leads abandon the purchase while in the process.

Functional Testing

It verifies that all the features and functions of the checkout process are working as per expectations. The payment page should load, the submit button must work without any glitches, any forms on the checkout page should load and take the right inputs, and all the calculations, taxes, and final product quotes should be right.

UI Testing

It validates the look and intuitiveness of the checkout page, including fonts, menu bars, text boxes, colors, images, buttons, and any UI element that users interact with during the purchase process.

Security Testing

Anything related to payment is quite fragile and requires a secure gateway. Security testing is an important aspect of checkout tests that consists of verifying that the user data is safe throughout the process. In addition, implementing KYC verification in the process will add another layer of security. It will ensure that the person making the transaction is indeed who they claim to be. This is not only critical for preventing fraudulent activities but also for complying with various financial regulations

Cross-Browser Testing

This focuses on checking the checkout page on multiple browsers (sometimes varying OS and devices) to identify broken UI or functionality issues on individual browsers.

Regression Testing

Whenever you introduce any changes in the application, it is advisable to check related modules to ensure no issues arise up there. Similarly, if you have changed the UI of the cart or made modifications to the payment API, perform regression testing on the checkout page to prevent any defect from leaking.

Importance of Checkout Test

Users want accessibility and smoothness when making a purchase. Anything that is complicated or requires an extensive process often drives them away. This clearly shows in the statistics that highlight that almost 17% of customers who are ready to buy abandon their cart due to a complicated checkout process. No business wants that.

Many other reasons exist to perform checkout testing. Customers expect a seamless and secure payment process and want to complete the purchase without any delay/crashes. This makes it necessary to test the security and compatibility of the application on different browsers and devices. In a similar manner, the foremost requirement for any checkout page is to ensure that all the features and functions of the payment, including final quote calculation, payment options, and all necessary API integrations, are working properly.

Checklist for Checkout Test

Follow this checklist to make sure that you do not miss one single point while verifying the checkout page:

  • Successful API integrations for payment options.
  • Layout and checkout flow.
  • Accurate tax calculation and total price display.
  • Proper redirection for users who couldn’t successfully complete the checkout.
  • Cross-browser and mobile compatibility.
  • Correct notification message upon complete transaction.
  • Correct error message when users are unsuccessful in completing the transaction.
  • Security scenario when performing any transaction.
  • Check payment flow with the right encryption and fraud prevention methods.
  • Targeting the right location for delivery and shipping of the product.

Checkout Test Best Practices

A few best practices will assist you in easily following the checklist to execute checkout testing the right way:

  • Start with a basic idea of what you want on the checkout page, including UI elements, forms, buttons, and more.
  • Follow a set parameter or checklist to avoid missing out on any testing area.
  • Understand your target customers and test relevant fields on the checkout page accordingly.
  • Cover both positive scenarios (valid inputs) and negative scenarios (invalid inputs, error handling) to ensure robustness.
  • Keep in mind the privacy policy and regulations of the region of your business and incorporate the same in your testing.
  • Test that the final page shows all the calculations, taxes, extra charges, and addresses properly without any hidden costs.
  • Verify that all third-party integrations, such as payment gateways and shipping providers, function correctly during checkout.
  • Always run a regression test after you make any changes to the application that might affect the checkout process.
  • Review your test cases for the checkout process to confirm that what you are checking is right.
  • Whenever possible, automate the checkout test process using testing frameworks and tools to increase efficiency and reduce manual errors.
  • For automation testing, create test scripts that align well with the checkout flow testing.
  • Choose the testing tool for automation that works best for your needs and performs all the testing types for the checkout test seamlessly.

Test Cases for CheckOut Page

Here are some test cases that would help you with testing your checkout page:

Functionality and Flow:

  • Verify that the checkout process starts from the shopping cart.
  • Ensure the correct items, quantities, and prices are displayed in the cart before proceeding to checkout.
  • Test the ability to add or remove items from the cart during checkout.

User Information:

  • Test the input fields for collecting user information, including name, email address, shipping address, and billing information (if applicable). Also, check with invalid inputs.
  • Validate that mandatory fields are properly marked and must be completed before proceeding.
  • Test for correct formatting and validation of email addresses and phone numbers.
  • Verify that user data is handled in compliance with privacy regulations.

Shipping and Billing:

  • Ensure that the shipping methods and options are displayed correctly and the user can select their preferred shipping method.
  • Verify that the billing information matches the payment method being used. Ensure that you have a comprehensive understanding of all invoicing payment terms.

Payment Processing:

  • Test the different payment methods available (credit card, PayPal, etc.) to ensure they work as expected.
  • Verify that the payment gateway is secure and that sensitive information is handled safely. You can see our comprehensive blog on payment gateway test cases to run this verification.
  • Test for the proper handling of invalid or declined payments.

Order Review:

  • Check that the user is presented with a clear and accurate order summary before finalizing the purchase.
  • Ensure the correct taxes, shipping costs, and any additional fees are included in the total order amount.

Confirmation and Communication:

  • Verify that an order confirmation page is displayed after a successful purchase.
  • Check for automated emails confirming the order and providing order details to the user.

Cross-Browser and Device Testing:

  • Test the checkout process on different web browsers (Chrome, Firefox, Safari, Edge, etc.).
  • Check the process on various devices (desktop, mobile, tablet) to ensure a responsive and consistent experience.

When to Automate the Test Cases for the Checkout Page?

Automation takes over when manual demands much effort and time. And that is when you should automate tests for pages, such as checkout.

Payment checkout is a critical business process that deals with monetary transactions. Some testing types, like security, shipping and billing, and geolocation, are important to roll out a bug-free checkout page. But running these tests manually is hard; it demands immense human power, budget, and time. In such cases, automated testing saves both time and money by executing tests of such complex behavior.

Overall, you should automate the checkout flow tests when time-bound, manual, and complicated test cases are involved.

Here is a guide with in-depth discussions on the different characteristics of test automation.
