The issue lists many models/tables needing API tests. First, examine the existing test structure in the repository to understand the testing framework (likely PHPUnit) and how API tests are organized. Look for a test directory, possibly `tests/`, and see if there are existing model or API test examples. Then, for each listed model (e.g., Resources, Absences), locate the corresponding model file and its API endpoints. Write tests that cover basic CRUD operations for each, ensuring they run successfully. 'Done' means all checkboxes have passing tests.
