7/21/2023 0 Comments Python unittestAs part of each unit test you provide a set of inputs and then verify the output is the same you expected using the concept of assertions. Unit tests are called this way because they test units of your code, in this case the behaviour of the methods in the class User.Įach unit test should be designed to verify that the behaviour of our class is correct when a specific sequence of events occurs. Now that we have the structure of our test class we can implement each test method. The value of _name_ is checked when you execute the test_user.py file via the command line. Before adding the implementation to each test method let’s try to execute the tests to see what happens. We have created the structure of our test class. add an entry point to execute the tests from the command line using unittest.main.create a test class that inherits unittest.TestCase.To use the unittest framework we have to do the following: We will write our unit tests in a file called test_user.py. Now we will see how to use the Python unittest framework to write the three tests executed in the previous section.įirstly, let’s say the main application code is in a file called user.py. How To Write a Unit Test For a Class in Python That’s why unit tests are important as a form of automated testing. This is not a great approach, these are just three tests, imagine if you had to run hundreds of tests every time your code changes. However, the problem is that we would have to run these tests manually every time the code changes considering that any changes could break the existing code. These tests give us some confirmation that our code does what it should do. Self.profile = ".format(user1.get_level())) The only class attribute is a dictionary that stores all the details related to the user.
