      Getting some malformed data to test with

      1. Create a new course, and enrol a few users in it.
      2. Create a new assignment activity with submission types set to online text.
      3. As two students, complete the assignment.
      4. As a teacher or admin user, grade the students.
      5. Go to the course's grader report, by clicking Course administration -> Grades.
      6. Navigate to Grade administration -> Export -> Plain text file.
        • Export a CSV file using commas as the separator.
      7. Open the CSV file you generated.
        • Observe that the first line is a header row, with names for each data column.
        • Pick a subsequent row and completely excise a column from it - not just the data value, but the comma after it as well.
        • Save your CSV file as malformed.csv.

    Description

      If the number of columns in any data row don’t match the columns in the header row, there is no diagnostic warning, AND the ability to map from the select box in the “identify user by" section is broken.
