Implementing Unit Tests | Nose
“Nose” is a popular testing framework in Python, primarily used for writing unit tests. Nose is a test runner that extends the capabilities of Python’s built-in unittest module. It provides a simpler syntax for writing tests and offers additional features for test discovery, parallel test execution, and plugin support.
Installing Nose
pip install nose
Now, to perform unit tests using nose, we will make a file named as main.py and write the following test code.
main.py
def test_addition():
assert 1 + 1 == 2
def test_subtraction():
assert 3 - 1 == 2
To run this program, we will write the following command:
nosetests main.py
Output:
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.
