Create a moodle with a large number of students Make 2 feedback activities with lots of feedback, > 1000 responses (including some anon), one in a course and another at the site level Add different types of questions to make sure each type displays properly later in the export In the course feedback Analysis tab, try each of the download formats and make sure they work with feedback data. Check the column names are correct and in the right order, and the data matches the columns Confirm any anon data is correctly redacted. Repeat from a site level feedback instance using analysis tab (look similar but is different url) Repeat with groups mode selected, and confirm the file name show the group, and an extra group column has been added and is correctly populated Test exporting multiple large feedback downloads at the same time, and also browsing the site somewhere else at the same time, the report download should not block other pageviews. In my test box I'm downloading an export with 1000 responses x 12 questions = 193kb file in < 2 seconds and only using peak of 7M of php memory
