1. Prepare a new instance of the Workshop module 2. In the settings form, check "Use examples" 3. Define a simple assessment form 4. Add one example submission and provide the reference assessment for it 5. Switch the workshop to the submission phase 6. Log in as a student 7. Assess the submission and click "Save and close" 8. TEST: At the page where the reference assessment is compared with the student's assessment, make sure that the header link of the student's assessment leads to a correct page and does not throw error. 9. TEST (advanced): Copy the URL of the page displayed in step 8 (where exacompare.php is opened). Log in back as the teacher who created the workshop and paste that URL to the address bar of the browser. Make sure that now the header links in both reference assessment and the student's assessment lead to correct pages and do not throw error. Note: In workshop, there is no UI yet how the teacher can see student's assessments of example submissions. Hence the trick with manual copy&paste of the URL. However, one day such UI might be added and so we want the page work well already now. Note: The assessment header does not render as a link if it would lead to the same page of if the user does not have permission to see that page. So when the student is comparing their assessment with the reference one, there is no link displayed in the header of the reference assessment.
