ATM Machine Test Cases: In this post, you’ll find some ideas for positive and negative test cases. Depending on the design of the ATM terminal, following positive and negative test cases can be formed. If you’re familiar with the bank’s terminal, you may notice that there are always more test cases that you can check for and verify if the software functions as expected. The more you know about any bank’s ATM terminal, the more you can write in your test cases. You can also take a walk outside and check out the functionality of your debit card in nearby ATM.
Note: ATM Test cases may vary from one bank to another due to the way these terminals are designed. Also, each bank has it’s own way to handle the sequence in which cash is being taken out. For example, some banks require additional PIN entry before the money is taken out for an extra layer of security. Some banks don’t allow free withdrawal from other banks ATM etc. However, the functionality for some of the ATM Machines can be visualized in general. In this post, I’m assuming a lot of functionality of ATM, which you may or may not notice for your bank.

Test Cases for ATM
In this post, we are going to learn how we can write the test cases for an ATM Machine. In our previous post, we have shared so many test cases for freshers and experiences, and if you have to check them yet, then you can check those manual test cases using this link.
As we all know that in our daily life we are using ATM machines for money withdraw and these machines are working for 24×7. As by this machine, we are dealing with the money, so it’s very much important to test the application with respect to its accuracy, reliability, and performance.
Below we are trying to cover as much as possible test scenarios for the ATM machine. In the below, we try to cover both the positive and negative test case scenarios for the ATM machine.
- Verify the ‘ATM Card Insertion Slot’ is as per the specification
- Verify the ATM machine accepts card and PIN details
- Verify the error message by inserting a card incorrectly
- Verify the error message by inserting an invalid card (Expired Card)
- Verify the error message by entering an incorrect PIN
- Verify that the user is asked to enter the PIN after inserting a valid ATM Card
- Verify that PIN is encrypted
- Verify that there is an action like blocking of card occurs when the total no. of incorrect PIN attempts get surpassed
- Verify the user is allowed to do only one cash withdrawal transaction per PIN request

- Verify the message when there is no money in the ATM
- Verify the language selection functionality

As you can see we have a lot of positive and negative test cases in the case of the ATM machine. You can extend the test cases depending on the requirement document and specification as per the bank or the card type. You may even add test cases for credit cards and other gift card based operations. You may also have to add a few more security-related test cases.
