What is unit testing in Python and how do I implement it?
Unit testing in Python is a method to test individual units of code for correctness. You can implement it using the unittest
module.
Can you show me a simple example of a unit test?
Sure! Here's a basic example:
import unittest
def add(a, b):
return a + b
class TestMathFunctions(unittest.TestCase):
def test_add(self):
self.assertEqual(add(1, 2), 3)
if __name__ == '__main__':
unittest.main()
How do I run the tests?
You can run the tests by executing the script in your terminal. Just run python -m unittest your_test_file.py
.
What are some best practices for writing unit tests?
Some best practices include writing tests for every function, keeping tests isolated, and using descriptive names for your test cases.
