Tests

[PhilippImhof]

This issue is meant to keep track of stuff that can / should be done w.r.t. automated testing.

Unit tests

• [x] is every function covered?
• [x] check of no. of arguments for each function
• [x] write specific unit tests for implementation of
  • [x] concat
  • [x] diff
  • [x] fill
  • [x] join
  • [x] len
  • [x] map
  • [x] poly
  • [x] shuffle
  • [x] sort
  • [x] str
  • [x] sublist
  • [x] sum
• [ ] use strings from language file when checking for error messages (consistency)
• [x] use data providers for better diagnostic output
• [ ] regrading

Behat

• [x] switch between easy and expert mode for grading criterion (one part / multiple parts)
  • [x] given simple / expert criterion -> form initialisation correct?
  • [x] valid simple criterions, switch to expert mode -> correct value shown?
  • [x] invalid simple criterions -> what happens?
  • [x] easy criterion, switch to simple mode -> conversion working?
  • [x] set criterion (simple mode), submit -> correctly saved?
• [ ] delete parts (once this is implemented via a button + javascript)
• [x] variable instantiation (number of datasets, which dataset to show, preview)
• [ ] backup/restore for questions including an image
• [x] question usage in a quiz (port mobile tests to browser)
• [ ] backup/restore of a course containing formulas question
• [ ] moving of question between categories, with/without images, also move category to another parent category
