Output Tests
This is an example of how you can test the output stream of student code.
This test makes sure the student's code prints
"Hello World". It assumes the student's file name is example.py. Replace the import with whatever you student's file name is. Note: This code converts the output to all lowercase and removes spaces to compare against the correct value.
import unittest
import sys, io
stdout = sys.stdout
class CodingRoomsUnitTests(unittest.TestCase):
def setUp(self):
global stdout
stdout = sys.stdout
sys.stdout = io.StringIO()
def tearDown(self):
global stdout
sys.stdout = stdout
def test_default_case(self):
import example
output = sys.stdout.getvalue().strip("\n")
answer = "Hello World".casefold().replace(" ", "")
student = output.casefold().replace(" ", "")
self.assertEqual(answer, student)
if __name__ == '__main__':
unittest.main()
example.py
print("Hello World")
