However, please note that this will only work if you’re running Python3 on your machine. Now to run the above code we can run the command below in our Terminal. We want to write a test method named ‘testadd’ and we are going to give it some numbers to test and assert that the actual outcome that we will get is the one we were expecting. Now we can start to write the basic tests for our code. We also need to inherit from unittest.TestCases. For example, say you have a function to validate the format of an account number that a. All tests need to be under a descriptive class in this case we will name it ‘AdditionTest’. Both the unittest and pytest frameworks can be used to write unit tests. We are going to import the Python unittest framework as well as the function that we are running tests on which in this case is named add_10. The file name should be preceded or followed by the word ‘test’ separated from the filename by an underscore. Tests are normally written in a different file that is conventionally named in two ways. Now we want to write some tests for this simple function to ensure that it performs as we would expect. The function below takes in a number as an argument and adds 10 to it.Īnd if we change the argument that we are passing to the function from 5 to 7 then we get a different output. In this article, we will write tests on a simple function using a common testing framework called unittest. Python unittests can be used to test single functions, entire modules or a complete interface. in this article, we’ll show you how to use Python unittesting methods.

Python unittesting is a type of software testing where individual units of a program are tested to ensure that they meet a given set of standards and that it is performing as intended.
