The correct call to action for the first line of code in a unit test should typically be to define a test case class. Therefore, the most appropriate option from your list would be:
def()
This suggests starting with a function definition (though in practice, you'd want to define a class that inherits from unittest.TestCase
). However, since the context is limited to the options you provided, this option is the closest fit for a starting action in a unittest context.
In a complete unit test setup, you would typically have something like:
import unittest
class TestMyFunction(unittest.TestCase):
def test_example(self):
self.assertEqual(1, 1)
But from your given choices, the correct starting action is implied to be defining a function or class.
