What is unittest in python?

Answer 1

Unit Testing is the first level of software testing where the smallest testable parts of a software are tested.

To use unittest:
```
import unittest

class Test(unittest.TestCase):

def test(self):
self.assertTrue(True)

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