Check Variable Values

Simple variable value

To check a variable value you need to import the student's code and use dot notation to get the value.

Example, maybe you ask students to assign a variable named num1 the value of 5.

Student Code:

example.py

num1 = 5

Grading Tests:

import unittest

class CodingRoomsUnitTests(unittest.TestCase):

    def test_default_case(self):
        import example
        self.assertTrue(example.num1 == 5)

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

Number of items in a list

You can do anything you need to with a student's variable value. For example, we can see if a student created a list with at least 3 items using the len() function.

Student Code:

example.py

my_list = ["first thing", "second thing", "third thing"]

Grading Tests:

import unittest

class CodingRoomsUnitTests(unittest.TestCase):

    def test_default_case(self):
        import example
        self.assertTrue( len(example.my_list) >= 3 )

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