Q: What are Python Testing Frameworks?

In this example, we first imported the Pytest module. After that we have defined a function func(x). In this function, it adds 5 to x and returns the result. Then, we defined another function named test_method. It uses an assert statement to check whether the result of func(3) is equal to 8. The purpose of this test is to verify that when you pass 3 as an argument to func, it correctly adds 5 to it, resulting in 8. If this condition is true, the test passes; otherwise, it will raise an assertion error.

Advantages of Pytest

UnitTest: ‘unittest’ is a bilt-in testing library in Python. It follows the xUnit Style and provides a tests discovery mechanism.
pytest: Pytest is third party testing framework that is widely used for its simplicity and powerful features. I has arich est of plugins and support fixtures, parameterized testing , and more.
nose2: “nose2” is an extension of the older “nose” testing framework. It provides test discovery and a variety of plugins for additional features.
doctest: “doctest” allows you to tests directly in your documentation and it extracts and runts tests from docstrings in your code.

Getting Started with Pytest

Python Pytest is a framework based on Python. It is mainly used to write API test cases. It helps you write better programs. In the present days of REST services, Pytest is mainly used for API testing even though we can use Pytest to write simple to complex test cases, i.e., we can write codes to test API, UI, database, etc.

In this article, we will learn about What is Pytest, the Installation of Pytest, and How you can write the test.

Conclusion

It’s better to test your programs in Visual Studio code. Make sure Python has to be installed in your system and its extensions have to be installed in VS Code before testing your code.
