How do I write tests using Nose?

To write tests using Nose, you need to create a test file that starts with 'test_' and define test functions within it.

Can you give me an example of a simple test?

Sure! Here's a simple test:

import unittest

def add(a, b):
    return a + b

class TestMath(unittest.TestCase):
    def test_add(self):
        self.assertEqual(add(1, 2), 3)

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

You can run the tests by navigating to your test directory in the terminal and executing the command nosetests.

What if I want to test a specific file?

You can specify the file by running nosetests your_test_file.py in the terminal.
