A unit test should be imported from the standard library. Make a class called TestSum that is an inheritor of TestCase. Add self as the first argument to the test functions to make them into methods.
When utilizing the unit test module, which class do we inherit to create a straightforward testing class?The function you want to test, formatted name(), and a unit test must first be imported. Following that, you develop a class, such as NamesTestCase, which will house tests for your formatted name() function. This class is descended from the unit test class. TestCase.
Why is pytest inferior to unit test?Unittest mandates that programmers construct classes inherited from the TestCase module, where the test cases are then specified as methods. For Pytest, however, all you need to do is declare a function with "test_" before it and utilize the assert conditions inside of it.
