editing fee of a student who has already paid doesn't show a warning / give an error and automatically change the revenue

[nus-pe-bot]

Description Currently, if i have a student who has been marked as paid already, and I edit the student to increase/decrease his fee. There is no warning showed, and the total revenue is directly changed by the App.

Steps to reproduce From sample data, mark a person as paid -> here i marked charlotte

Calculate revenue using revenue paid

Shows 100.

Edit charlotte's fee using edit 1 f/1000

calculate revenue using revenue paid again

Actual Output: Charlotte remains marked as paid and revenue is automatically adjusted to $1000 (we don't know if the difference has been paid yet).. Expected Output: A warning is displayed saying the person is marked as paid, asking if we want to unmark the person / adjust according to the amount paid alr etc..

This is a major bug, in this feature as it may show inaccurate results for money-related matters which is a sensitive and important topic. Money handling should be very carefully done, and I feel this bug makes the product unreliable for most users. Hence severity high

Team's Response

This is actually the intended use case of the fees field to highlight the outstanding fees of the user - for example, that the fees have increased from 100 to 1000 which the student has yet to pay. The tester has mentioned a suggestion that is not a functionality bug of our app.
