Pull request overview
This PR adds comprehensive unit tests for the emailService.js module using Node.js's native test framework (node:test) and experimental module mocking capabilities. The tests cover the dual-mode behavior of the email service (development vs production), error handling, and parameter handling.
Changes:
- Added unit tests for emailService.js covering dev mode simulation, production mode email sending, HTML content handling, and error scenarios
- Implemented proper mocking of the nodemailer dependency using node:test's mock.module API
- Set up environment variable management to test different configuration scenarios

Missing test coverage: The test should verify that createTransport is called once during module initialization. Since the transporter is created at module load time (emailService.js line 4), not during sendEmail execution, it would be valuable to verify that createTransport was called with the expected configuration. Consider adding an assertion after module import to verify createTransport was called.

Missing test coverage: No tests verify behavior when required parameters (to, subject, text) are missing, null, or empty strings. The sendEmail function doesn't validate these parameters, so it would pass undefined/null values directly to nodemailer. Consider adding tests for these edge cases to document the expected behavior and ensure the function handles them appropriately.
