Measure quality
Definition and example
Measure quality is the focus of this lesson. Keep 20 test questions and run them after every change. Score the answers by hand. The task asks you to apply that idea in a small example: How do you know the assistant improved. Before you run the code, predict what should happen. Then Inspect the result produced by the exercise and compare it with your prediction. If the result differs, change one relevant line and run it again. Testing one change at a time makes the cause of a result easier to understand.
