ATM Test cases

In this post, we will learn how to write ATM test cases. In the olden days, customers had to visit the bank’s home branch with a passbook to perform banking transactions. With expanding metropolitan city limits, changing lifestyles, and increasing traffic, visiting the bank for every transaction is quite an overhead for the bank customer in terms of effort, time, interest, and other logistics.
