Create a Test Program[edit | edit source]
Create the following Pytest test program. Save it as test_multiply.py
import multiply
def test_multiply():
assert multiply.multiply(2, 2) == 4
Test Success[edit | edit source]
Test the program by running pytest in a terminal or command prompt in the same folder as the two programs above and observe the results.
pytest
Test Failure[edit | edit source]
Change the multiply source code somehow, such as multiplying by 0 rather than multiplying by y. Test the program by running pytest again and observe the results.
