How can I test my Python classes effectively?

You can use the unittest module in Python to create test cases for your classes. Would you like an example?

Yes, please provide an example of a simple class and its tests.

Sure! Here's a simple class:

class Calculator:
    def add(self, a, b):
        return a + b

And a test case for it:

import unittest

class TestCalculator(unittest.TestCase):
    def test_add(self):
        calc = Calculator()
        self.assertEqual(calc.add(2, 3), 5)

Would you like to know more about running these tests?

How do I run the tests once I've written them?

You can run the tests by executing the command python -m unittest in your terminal. This will discover and run all test cases in your project.
