To verify that a user can register an account (singup) when users are managed locally by Harbor (DB mode).
# References:
User guide
# Environment:
* This test requires that a Harbor instance is running and available.
* Harbor is set to authenticate against a local database. ( auth_mode is set to **db_auth** .) The user data is stored in a local database.
* A linux host with Docker CLI installed (Docker client).
# Test Steps:
1. On the Harbor's home page, click "Sign Up"
2. Enter user information to register a user.
3. Use the username of the newly registered user to log in to the UI.
4. Log out from the UI.
5. Use the email of the newly registered user to log in to the UI.
5. On a Docker client host, use `docker login <harbor_host>` command to verify the user can log in by either the **username** or **email** . (check both)
6. Log out from the UI and register a another new user. Try to provide invalid values of input to see if validation works:
