feat: Improve testing coverage for the POST and PATCH methods of the resources

[imjoey]

Feature request

Please describe your feature

At present, most test cases in Backend E2E and Unit-test cases are using PUT method for creating and updating the resource, which leads to extremely low testing coverage for creating by POST and updating by PATCH.

Describe the solution you'd like

So it would be much better that if we could add more test cases for the POST and PATCH methods of the resource. Of course, I would say adding missing test cases is heavy work, so let us fix this gradually.
