Purpose

Decide whether the bot stops after 5 minutes and prints the cookies per second, which completes the assignment's required behaviour (lecture step 4).

Deliverable

A time-limited main loop, the cookies per second calculation and output, a command-line entry point, a recorded 5 minute container run and the screenshot for lecture step 4.

Go / No-Go Criteria

# Criterion (objectively checkable) Go No-Go
1 A full containerised run lasts 300 seconds with a deviation of at most 10 seconds Elapsed time within 290 to 310 s Outside the range
2 The run prints exactly one line cookies/second: N One line printed None or several
3 The calculation is unit tested with a fake clock and fake driver 0 failures A test fails
4 docs/images/step-4.png exists and the run result is recorded in the wiki source Both exist Either missing
5 The code review against qc-programming-python.md is Go RC-* is Go No-Go

Tasks

# Task Summary Needs its own Use Case/User Story? Reference
1 Stop after five minutes Implement the main loop that runs for the duration in constants.py (300 seconds) using a monotonic clock, so a test can use a short duration and a fake clock. No O3
2 Calculate and print cookies per second Read the game's own cookies-per-second figure and the total cookies baked, and print cookies/second: N when the run ends. Tests cover the formatting and the calculation. No O3
3 Add the command-line entry point Add a main function and a console script so python -m or the installed command starts the bot. Options come later in lecture step 5. No O3
4 Do and record the five minute run Run the bot for a full 5 minutes in the container, keep the printed result and save step-4.png. The result is the baseline for step 5. No O3
