A guest can navigate a course with guest access

This is an exploratory test, so please feel free to try anything you like and not just the test steps!

This test requires a site which allows guest access i.e. the guest login button is set to show and also a course with a variety of activities which has guest access as an enrolment method.

1. Log in as a guest and verify that the home page and links are displayed as expected for a guest.
2. Go to the course and verify that the course page displays as expected for a guest.
3. Go to each activity and verify that it displays as expected for a guest, such as for a forum or a quiz you are prompted to log in with a full user account.
