Test Case For Payment Gateway

Payment Gateway Test Case: Payment gateway testing is quite common for testers who work in the startup or the service industry. I have decided to write this post for those who have asked for the test cases of such gateways in the past.

The current images of the payment gateway options shown below are from CCavenue’s payment gateway used on one of the leading phone recharge websites in India. The options offered in the payment gateway are for Debit cards, Credit Card, NetBanking, ATM Card, EzeCard(American Express).

We are going to follow the modular approach to test the payment gateway options. So for manual testing, let’s start with writing test cases for each of the payment options. First, let’s check out the payment gateway options screenshot. This screenshot you can use to write down initial test cases.

As you can see, you’re presented with multiple options for the payment. So the test cases for this part of the payment gateway are as follows.

Default Payment Gateway Options Test Cases

• Check if each of the payment options is selectable.
• Check if the each listed payment option opens the respective payment option as per specification.
• Check if the payment gateway defaults to the debit card option.

How to Test Payment Gateway Functionality?

To test payment gateway functionality is the same as testing any other functionality. You should have some test strategy during testing it. The following are some points kept in mind during the testing of the payment gateway:

• Gather appropriate test data for the dummy credit card numbers for various master cards.
• Gather payment gateway information like whether used PayPal, guest pay, etc.
• Gather payment gateway documents with error codes – useful if any error came during testing to identify whether it’s our application fault or payment gateway-related error.
• Check is the gateway does what it is supposed to do? Does it handle order objects correctly? Does it perform additional calculations correctly?
• Understanding of the integration of the payment gateway with application
• Understand and test the parameters and sessions passed through the payment gateway and application
• Understand and test the amount of related information passed through query string or session or variables in any form.
• Check the format of the amount with currency format
• Check the language of the application and payment gateway language
• Try to change the payment gateway language during the payment process
• Test after successful payment all the necessary data retrieved to our application or not
• Check what happens if the payment gateway goes down during the payment process
• Check what happens if the payment process went successful but do not return to our application
• Check what happens if the session goes time out during the payment process
• Check what happens in the backend during the payment process is the session data stored in a temporary table, or any id is generated or not?
• Check what happens if the payment process is fail
• Check if any modification transaction is going on through the payment gateway, then how much amount is taken out as a modified amount, whether required to pay more or not. For example- if the modified amount is greater than the paid amount then and then only the application redirects to the payment gateway; otherwise, it should not.
• Check DB entries for the transaction whether they store credit card details and all or not
• Check DB entries for the amount-related fields in the database for the fresh transaction, modified transaction, and canceled the transaction.
• Check the error page during the payment gateway process
• Check security passes for the transaction
• Sometimes payment gateway sent confirmation through popup dialogs – so test popup blocker related settings also. What happens is the popup blocker is on and all this.
• Check buffer pages between application and payment gateway (firefox firebug add-on will be helpful to test)

These are some of the test cases which I think should be included in your test design. You can add validation for the text fields. You can also go for the validation for the automatic detection of the options.

I can add even more to the above options, like checking each bank option and seeing if the gateway transfers the user to the respective website. Again for sandbox usage and with manual testing, this will take a lot of time. But these are pretty much simple enough test cases for the payment gateway.

Feel free to let me know if you have any other suggestions or feedback. I’d appreciate your comments on the test cases.
