"""
Test Email Script — Service Finder
====================================
Tests the EmailManager by sending a test email using the configured provider.
Reads all settings from .env automatically via the app's Settings class.

Usage:
    # Test with configured provider (Brevo API / SMTP):
    docker compose exec sf_api python3 /app/test_email.py

    # Test with local Mailpit (no real email sent, no TLS needed):
    docker compose exec sf_api /bin/sh -c " \
      SMTP_HOST=sf_mailpit SMTP_PORT=1025 SMTP_USER= SMTP_PASSWORD= \
      EMAIL_PROVIDER=smtp TEST_RECIPIENT=kincses@gmail.com \
      python3 /app/test_email.py"

    # Test with Brevo API directly:
    docker compose exec sf_api /bin/sh -c " \
      EMAIL_PROVIDER=brevo_api TEST_RECIPIENT=kincses@gmail.com \
      python3 /app/test_email.py"

Environment check:
    - EMAIL_PROVIDER=smtp       → uses SMTP
    - EMAIL_PROVIDER=brevo_smtp → uses Brevo SMTP relay
    - EMAIL_PROVIDER=brevo_api  → uses Brevo REST API
