# Step 5 - Follow

`follow()` finds every "Follow" button in the followers list and clicks it with a one second pause between clicks, so the bot looks less like a machine. Buttons that already say "Following" are skipped.

If a click is intercepted by the "Unfollow?" pop-up (an account that is already followed), Selenium raises `ElementClickInterceptedException`. The bot clicks "Cancel" and carries on with the next button.

## What we gained

- Handling a specific exception on purpose: no bare `except`, and only the case the assignment describes.
- Testing that error path with a fake driver that raises the exception.
- Respecting the service: one second between clicks, and a mock service with a "Reset Share-a-Naan" button for clean re-runs.
