Summary

This PR introduces unit tests for the env utility functions to ensure their correctness and reliability. The following tests are included:

• getEnvironment function:

  • Verifies it returns an empty string when process is undefined.

  • Confirms it returns an empty string for non-existent environment variables.

  • Ensures it retrieves the correct value for existing environment variables.

• isDev function:

  • Validates that it returns true when NODE_ENV is set to development.

  • Confirms it returns false when NODE_ENV is set to production.

• isOnServerSide function:

  • Ensures it returns true when window is undefined (indicating server-side execution).

  • Verifies it returns false when window is defined (indicating client-side execution).

The tests utilize vitest for mocking and assertions, and proper cleanup is performed after each test to avoid side effects.
