Hey @cedricongjh,

I've submitted a PR to increase the test coverage, but I'm unsure if I've taken the best approach. Could you provide some guidance on how I can ensure better coverage? I feel a bit lost regarding what specific tests or areas would be most beneficial to focus on. Appreciate any feedback or direction you can offer!

hi @sdpunit, as described in the issue #12588, we should first check the codecov for the particular component: https://app.codecov.io/github/TEAMMATES/teammates/blob/master/src%2Fweb%2Fapp%2Fcomponents%2Fadding-question-panel%2Fadding-question-panel.component.ts. Afterwhich, create tests to cover the lines that are currently not being tested.

Do refer to the documentation: https://angular.io/guide/testing-components-scenarios#component-testing-scenarios for the types of tests as well, and refer to other tests that have been written already in the project

Folks, This PR seems to be stalling (no activities for the past 7 days). 🐌 😢
Hope someone can get it to move forward again soon...
