How can I test Python wrappers effectively?

You can test Python wrappers by using unit tests, integration tests, and mocking external dependencies.

What tools can I use for testing in Python?

Popular tools include unittest, pytest, and mock for creating tests and handling dependencies.

Can you give me an example of a unit test for a wrapper?

Sure! Here's a simple example using unittest:

import unittest
from my_wrapper import MyFunction

class TestMyFunction(unittest.TestCase):
    def test_case_1(self):
        self.assertEqual(MyFunction(1), 2)

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

How do I handle exceptions in my tests?

You can use the assertRaises method in unittest to check for exceptions. For example:

with self.assertRaises(ValueError):
    MyFunction(-1)
