Insufficient Test Coverage

While some test cases were present—such as verifying that an admin user could log in—overall test coverage was lacking. There were no negative test cases to confirm that non-admin users would be correctly rejected, and many critical parts of the application had no tests at all.

Robust test coverage is essential for catching common bugs, ensuring that a function or flow behaves as expected, and preventing regressions during active development. Expanding test coverage, particularly for core components, would improve the reliability and maintainability of the codebase.
