Grades import: auto-mapping of grade items and user identifier field

Create a new course and enroll some students in it. Add 1 assignment in the course named "Assignment 1" and 1 new grade item named "Grade item 1" in "Grade administration > Categories and items > Simple view", "Add grade item" button. Export grades to CSV file (Plain text file with comma separator). Import grades from the exported CSV file : go to "Grade administration > Import > CSV file", upload file and click on "Upload grades" button. Assert that the lists from "Identify user by" section contain the following values: Map from = "ID Number" Map to = "ID Number" Assert that the lists from "Grade item mappings" section contain the following values and that the others are set to "Ignore": Assignment: Assignment 1 = "Assignment: Assignment 1" Grade item 1 = "Grade item 1" Manually update the CSV file to add 2 columns with the following header names: "Assignment: Assignment 1 (Feedback)" "Grade item 1 (Feedback)" Import grades from the modified CSV file. Assert that the lists from "Grade item mappings" section contain the following values and that the others are set to "Ignore": Assignment: Assignment 1 = "Assignment: Assignment 1" Assignment: Assignment 1 (Feedback) = "Assignment: Assignment 1 (Feedback)" Grade item 1 = "Grade item 1" Grade item 1 (Feedback) = "Grade item 1 (Feedback)" Manually update the CSV file so that none of the header columns could be mapped (Add a random number at the end would do the trick) Import grades from the CSV file. Assert that the lists from "Identify user by" section contain the following values: Map from = (The first header column name from the CSV file) Map to = "User ID" Assert that the value from all the lists from "Grade item mappings" section are set to "Ignore".
