Review and execute the Assignment3.py file, and the manual for the Python unit test library.

A. Add at least 2 additional tests cases that you could use to test the return_add_pair function after test_one. Modify the function of return_add_pair to include a space between the + sign (i.e., 1+2 vs 1 + 2), and update the tests accordingly so that they pass .

B. How would you describe the software process you used to accomplish question A? Which of the primary software activities did you perform, and in what order?

C. If you were to accomplish Question A again, would you use the same process you used the first time? Given the opportunity to do it again, what would you change about your approach to Question A and why?
