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()
