What We Are Learn On This Post

**Test Cases For Calculator Template:** We can see that the experienced and the fresher tester is often asked to write the test cases for the calculator, and if you want to check the previous **Blackboard test cases****,** then you can check.

Many times the type of calculator is not mentioned. Test cases may be different for different calculators depending on the type like scientific, straightforward, financial, or some other specific calculator like a programmable calculator.

For the sake of simplicity, we are choosing a simple calculator for the test cases. You can come up with plenty of test cases to test a calculator based on mathematical computation. However, we are here testing the application to see if it is fit for consumer use.

So we have to make sure that it fits for the most apparent tests. If those tests are passed, then we can safely assume that the product is fit for use.

**Test Case For ****Calculator**

Here we are taking Ubuntu Linux’s calculator as an example of my test case. You can use the below image or use the one that comes with your operating system.

**Basic Calculator Test Cases Template**

Write the test cases based on the following functions and scenarios.

- Check the calculator if it starts by on button. If it is a software-based calculator, then check if it begins via specific means like from searching for a calculator in a search bar and then executing an application. Or by accessing menu items in Windows.
- Check if the calculator window maximizes to the specified window size.
- Check if the calculator closes when the close button is pressed or if the exit menu is clicked from the file > exit option.
- Check if the help document is accessed from Help > Documentation.
- Check if the calculator allows copy and paste functionality.
- Check if the calculator has any specific preferences.
- Check if all the numbers are working ( 0 to 9)
- Check if the arithmetic keys ( +, -, *, %, /) are working.
- Check if the clear key is working.
- Check if the brackets keys are working.
- Check if the sum or corresponding key is working.
- Check if the square and square root keys are working.

**Functionality Test Cases**

- Check the addition of two integer numbers.
- Check the addition of two negative numbers.
- Check the addition of one positive and one negative number.
- Check the subtraction of two integer numbers.
- Check the subtraction of two negative numbers.
- Check the subtraction of one negative and one positive number.
- Check the multiplication of two integer numbers.
- Check the multiplication of two negative numbers.
- Check the multiplication of one negative and one positive number.
- Check the division of two integer numbers.
- Check the division of two negative numbers.
- Check the division of one positive number and one integer number.
- Check the division of a number by zero.
- Check the division of a number by a negative number.
- Check the division of zero by any number.
- Check if the functionality using BODMAS/BIDMAS works as expected.

**Test Cases For Advanced Calculator**

Some of the advanced scientific calculators have the converter option. It does the conversion of angle, length, weight, area, volume, duration, currency, temperature. If your calculator has advanced features, as shown in the screenshot.

- Check is the user can do the operations like sin, cos, tan, and cos using the keys.
- Check is the operations like x-1, x!,|x|,x^y, and f(x) are functional and works as expected.
- Check is the log key is operational and functions as expected.
- Check the natural logarithm key are operational and works as expected.
- Check the factorial key is working as expected.
- Check the real and imaginary component keys are working as expected.
- Check the sophisticated conjugate keys are working as expected.

There are hundreds of test cases that we can make based on the operation of single and combination of the keys. I have given the test cases here to provide you with a head start. It may help you with the interview purpose, or it can be used for writing your test cases where there is a use of a calculator. Hope you have found this test case tutorial helpful

We try to post all the possible scenarios for Calculator test cases, but if you found any missed test cases, you can mention them in the comment section so that we try to update them in our Software Testingo post.
