In this course is that we're gonna learn how to test applications with python unittest framework.

Unit Testing is the first level of software testing where the smallest testable parts of software

are tested. This is used to validate that each software unit performs as designed.

The unittest test framework is Python xUnit style framework.

In this article, we will learn about unittest framework with the help of examples.

You're gonna learn the basics concepts of applications testing such as:

• Individual unit of testing

• Make preparations and sharing test data by using test fixtures

• Test code organization

• Test grouping using TestSuite

• Test skipping

• Execution of test collections

• Mocking of objects and functions

• Using mock decorators for objects patching

You'll also learn how to use mock objects. Mocking Test is a technique or method

used in testing within the scope of software testing by replacing the

original object (dependent object) with a mock object.

The mock object created can simulate the behavior of the dependent object that

is temporarily replaced. Testing in mock testing focuses on the unit being tested

without involving or depending on other units by isolating the object to be tested.
