Here are a few comments after the exploratory testing session on MDL-31276.

Invalid grades should not be outputted

As the only the last 3 grades are valid, we should not display the other ones.

Set grade for Bebe Stevens to 125

Set grade for Kyle Broflovski to abcde

Set grade for Timmy Burch to 9999999999999

Set grade for Clyde Donovan to ##

Set grade for Kenny McCormick to 10*30

Set grade for Stan Marsh to 0

Set grade for Jimmy Valmer to 100

Set grade for Butters Stotch to 76

File naming

I don't understand the bit with the time in the file name, it was between 1.30pm and 2.30pm and the files were:

• Grades-Soldier-Assign me-12-20120912_0549-comma_separated.csv
• Grades-Soldier-Assign me-12-20120912_0605-comma_separated.csv

What does 0549 or 0605 stand for?

Also, my +1 for a lowercased file name without special characters such as spaces, etc...

Confusion on when the grades will be updated

I was a bit confused (and still am) on when a grade is actually updated when the overwrite checkbox is unticked. Is it required to update the modified time in the CSV? If yes, that probably needs to be explained somewhere and it did not occur to me that I had to edit this value. If not, then I had some random behaviours and cannot tell when the grade will be updated or not.
