How can I use unittest with Python extensions?

You can use the unittest module to test Python extensions by writing test cases that import your extension modules.

Can you give me an example of a test case for a Python extension?

Sure! Here's a simple example:

import unittest
import my_extension  # Your Python extension

class TestMyExtension(unittest.TestCase):
    def test_function(self):
        self.assertEqual(my_extension.my_function(2, 3), 5)

if __name__ == '__main__':
    unittest.main()

What if my extension uses C code?

You can still use unittest! Just ensure your C extension is properly compiled and imported in your test cases.
