What is Python Unit Testing?
Python Unit testing is a software testing technique where individual units or components of a software application are tested in isolation from the rest of the system. The primary goal of Python unit testing is checking the validation that each unit of the software performs as designed, according to its specifications. Each unit test looks at a small part of the code, making sure it works even when things get a little tricky.
By testing each piece alone, programmers can find and fix mistakes early on, just like finding a little hole in a sock before it gets bigger, also developers can identify and fix bugs early in the development cycle, leading to better code quality and more robust software.
The main idea with unit testing is to make sure the code works well and won’t cause problems later on. So, by doing these tests as they’re building the program, developers can make sure it’s strong and won’t break when people use it.
Types of Python Testing Frameworks
Python has two main frameworks to make unit testing easier:
- Unittest
- Pytest
- Nose or nose2
- Doctest
Getting Started With Unit Testing in Python
In Python, unit tests are the segments of codes that are written to test other modules and files that we refer to as a unit. Python Unit Testing is a very important part of the software development process that helps us to ensure that the code works properly without any errors. In this article, we will learn about Python Testing with the help of examples and proper explanations.
