Prep

• All problems today revolve around troubleshooting and finding errors in some “launch code”-esque checks
• You will want at least someone to have downloaded the all the lecture contents linked in Discord
• To get rich installed easily, I have included a Python file in the contents that you should just need to run, and it will (in theory) handle things automatically for you.
  • You’ll need this for the problems today

Problem 1: Stress Tests

• The p1.py file is doing some stress testing, but has some issues
• Focus on using print statements to track down where things are going wrong
• How could you get around this issue?

Problem 2: Systems Go?

• The p2.py file should be saying that all systems are a go, but it is not
• Pay particular attention to the documentation to figure out what has gone wrong
• You should be able to fix all the problems by only changing 3-5 lines

Problem 3: Sufficient Shields?

• The p3.py file should also be saying that all systems are go, but is not
• Instead of using print statements here, use only your debugger to track down what is happening and how to fix it

Problem 4: System Scanning

• Finally, p4.py should be verifying a scan, but is instead erring out. Use the printed error alongside print statements or the debugger to establish where things have gone awry
• How can you easily fix this problem?

Writing Tests

• Let’s write a suite a tests for each of the library functions
• Always a good idea to target assert statements at both typical values, but also edge cases
• Let’s try to come up with at least 3-4 for each function
