Summary

This PR introduces unit tests for the toSnakeCase and isObject utility functions to ensure their correctness and reliability.

Changes:

1. toSnakeCase Tests:

   • Verifies conversion of space-separated strings to snake case.

   • Tests handling of single words, empty strings, and strings with multiple spaces.

2. isObject Tests:

   • Confirms correct identification of plain objects and arrays as objects.

   • Ensures null, undefined, and primitive values are not falsely identified as objects.

These tests enhance code coverage and help prevent regressions in the utility functions.
