Create more unit tests (at least 2 tests)

[grunch]

We need to work on add more unit tests.

Examples here

I've submitted PR #700 that adds unit tests for utility functions.

Added tests for:

• plural() - 2 test cases
• isFloat() - 2 test cases
• toKebabCase() - 2 test cases

Total: 6 new test cases, all passing ✅

The changes only modify the existing test file with no production code changes, making it a safe addition for improved test coverage.

Update: PR #700 now has all checks passing ✅ and is ready.
