More interested in the product itself that was tested, since we also have a team for payments and transfers.

In one of the projects, I tested a product related to payments and transfers in the banking sector. It was a system that facilitated the transfer of funds between user accounts, including both internal and external transactions.

The main aspects of testing included:

• Verification of the correctness of fee calculations and currency exchange rates.
• Security validation: authorization, data encryption, fraud protection.
• Testing failure and recovery scenarios for transactions.
• Verification of integration with external payment gateways and banks.

For automation, API tests were used to verify business logic, along with load testing to assess performance under a high volume of transactions.
