grade_minmaxtouse not respected for overridden categories

Prerequisites

1. A course with a teacher and a two students (I'll call them student A and student B)
2. Additional grade category aggregation types enabled: "Site administration" > "Grades" > "Grade category settings" > select all the items under "Available aggregation types"
3. A gradebook with a category item with aggregation set to highest grade.
   • Set this up at "Course administration" > "Gradebook setup". Just enter the name, leave everything else at defaults.
4. 2 grade items in the grade category. Again, just enter a name, leave everything else at the default setting (except the category, set that to the category you just made).

Testing

The following is all done as the teacher:

1. Navigate to "Course administration" > "Grades", then "Grade administration" > "Single view"
2. Select student A and award them a grade of 60 for one grade item and 70 for another.
3. Select student B and award them a grade of 60 for one grade item and 70 for another.
4. Navigate to "Grade administration" > "User report" and view the report for student A. Verify the their total for the category is 70%
5. View the report for student B and verify the total for the category is also 70%
6. Navigate to "Setup" > "Gradebook setup" and edit the grade category.
7. Under "Category total" verify there is no mention of rescaling.
8. Change the maximum grade to 150.

10. Navigate to "Grade administration" > "Single view" and select student A.
11. Check the override box for the grade category and award them a grade of 150.
12. Verify on the user report that student A now has a mark of 100% for the category.

14. Expand the "Category total" section and verify a message is displayed explaining that grades have already been awarded and a decision must be made.

16. Choose to rescale the grades, and update the maximum to be 200
17. View the user report for student A and verify that they still have a mark of 100%
18. View the user report for student B and verify that they still have a mark of 70%
19. Change the max for the category to be 300, this time choosing not to rescale.
20. Check the user report for student A and verify that their mark is still 100% and the rande for the category is still 0-200
21. Check the user for student B and verify that they have a mark of 70% for the category and the range is 0-300
