For this assignment, we had to modify the two test functions. The first step was of course to read and understand the source code given to me. After that it was time to start trying stuff! At first, I thought I had to modify the add and subtract functions even though there was no TODO there. Obviously that was wrong and after 45 minutes of fumbling stuff around I realized I was in the completely wrong spot. So I took a step back, and carefully read through the TODO instructions. After another little while of trying different things, I kept getting an error that “increment” needed to be included in the function. The key was to modify these test functions to handle the failures correctly. In the test_overflow method, I adjusted the add_numbers function to avoid overflow, and in the test_underflow method, I made changes to the subtract_numbers function to prevent underflow. That’s when it all started to click and I was able to successfully complete the assignment. I will paste the complete raw console log on a separate page below because I wanted to include the code in the screenshot, and the screenshot wouldn’t be big enough for the entire console anyway. Starting Numeric Underflow / Overflow Tests!
