@cedricongjh I am a student at the Australian National University working with a 4 person team. We are interested in working on open source projects like this one. We are all new to this repository and would love to contribute to this issue. I see that there are certain test cases that need coverage.

Can we be assigned to: AddingQuestionPanelComponent CommentTableComponent

Let me know if these are available. If not please advise on which tests still need coverage. Thank you.
