Test Cases for ATM Machine

Test Cases For ATM Machine: In this article, we are going to discuss some of the primary and generic positive and negative test cases for the ATM Machine. If you want to know more of our previously discussed test cases or test scenarios. Here are those:

When you are starting testing the ATM Machine, you have to test all possible scenarios. Because if you have missed some of the test scenarios, then the organization has to face a considerable loss. So when you start testing ATM Machine a few things you have to keep in mind:

• Performance
• Accuracy
• Reliability

If you want to achieve all the above points for ATM Machine, then you have to test each separate component, after that integration testing after assembling all the elements, and finally, need to perform performance testing.

When the interviewer asked, to write the test scenario for the ATM Machine. That time the interviewer is looking at your approach towards the topic without details requirements on how you can write the test case? Because no one can write the test case without any test case document. So it’s the first action item before starting any test case is to ask for the requirement specification document.

Depending on the design of the ATM terminal, the 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 a 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 its 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.

Final Words

I hope after going through all of these test scenarios, you have got an idea about the ATM Machine because we are trying to cover UI, Positive, and negative test scenarios in our test cases for the atm machines.

You can take the below things as a challenge, and try to answer those. So, you can improve your knowledge:

In this post, we are trying to cover the widespread and generic scenarios of ATM machines. But still, we believe if you think about the more situation, then you may find some other scenario. Let us know in the comment section of the then missed scene so that we can update this article.
