Python pytest Unit Tests

#What is Python pytest?

Python pytest is a testing framework for the Python programming language that allows developers to write simple, scalable and maintainable unit tests for their code. It is an open-source and widely used testing tool that provides a simple way to write tests in Python.

#Python pytest Key Features

Most recognizable Python pytest features include:

• Simple and easy to learn: Python pytest is easy to learn, and its syntax is simple and expressive.
• Advanced assert functionality: The framework provides a rich set of assertion helpers that allow developers to write better and more readable tests.
• Supports fixtures: pytest supports fixtures, which are functions that provide a fixed baseline for tests to run on.
• Parametrization: pytest provides a way to run the same test function with different arguments, making it easy to test edge cases.
• Plugin architecture: pytest has a rich plugin architecture that allows developers to extend the framework’s functionality.
• Test discovery: pytest automatically discovers tests in files with names that match a certain pattern.

#Python pytest Use-Cases

Some of the Python pytest use-cases are:

• Unit testing: Python pytest can be used to write unit tests for individual components of a software application.
• Integration testing: pytest can be used to test the interactions between different components of an application.
• Regression testing: pytest can be used to ensure that changes to the codebase do not break existing functionality.

#Python pytest Summary

Python pytest is a simple and easy-to-learn testing framework for Python that supports advanced assert functionality, fixtures, parametrization, and has a plugin architecture. It can be used for unit testing, integration testing, and regression testing.
