Either the Moodle Quiz or the Moodle Assignment will work for untimed tests. The quiz activity will allow automatic grading of some question types, as well as feedback. The assignment activity allows both written and audio/video content, either as part of the instructions or the submitted materials. However, with the exception of audio or video under two minutes in length, content needs to be stored outside of the Moodle server (YouTube, Vimeo, Flipgrid, etc.) and linked or embedded.
Pros: Compared with timed evaluations, the untimed option does not put students with slow or intermittent internet at a disadvantage.
Cons: You can ask students to take pictures of written work, but unless they do this using a PDF conversion tool (GeniusScan, Camscan, etc.) it may be hard to work with those uploads
