+You cannot do too much unit testing for LRR because it almost does not
+have functions or classes.  However, you can do end-to-end testing.
+It is important that you *restore* the database each time before your
+run a test case.  The fixture *restore_database* in ./test/conftest.py
+is used to restore the database. Please check that.  A use case for
+this fixture can be found in the test script
+./test/SeleniumMpiana/test_bug418_yaaqob.py.  You could run this test script
+by typing the following command: `pytest ./SeleniumMpiana/test_bug418_yaaqob.py`

+Sign-Up Automation Test Script
+Overview
+This script automates the sign-up process for a web application using Selenium WebDriver. It tests whether form values are retained correctly if the initial sign-up attempt fails and requires modification of the student ID before resubmission.
+
+Prerequisites
+Python 3
+Selenium library
+Chrome WebDriver
+A running instance of the web application on http://localhost:8080
+
+Configuration
+Web Application URL: Make sure the web application is running at http://localhost:8080. Adjust the URL in the script if necessary.
+
+Update Element Locators: Ensure the IDs used in the script (signup_link, signup_form, full_name, student_id, email, password1, password2, signup_btn) match those in your web application.
+
+Run the script:
+
+Script Logic
+
+Open the Login Page: The script navigates to the login page of the web application.
+Click the "Sign Up" Link: It waits for the "Sign Up" link to appear and clicks it to navigate to the sign-up page.
+Fill Out the Sign-Up Form: It fills out the form fields (Full Name, Student ID, Email, Password).
+Submit the Form: It submits the form and waits for the result.
+Check for Sign-Up Failure: If sign-up fails, it checks if form values are retained.
+Modify Student ID: If the form values are retained, it modifies the student ID and resubmits the form.
+Verify Retained Values: It verifies if other fields retain their values after modifying the student ID.
+Print Retained Values: If the second attempt is successful, it prints the retained form values.
+Close the Browser: The browser is closed at the end of the script execution.
+
+
+
+The script provides the following output:
+
+Sign-Up Successful: Indicates the sign-up was successful on the first attempt.
+Sign-Up Failed: Indicates the sign-up failed on the first attempt and checks for retained values.
+Second Sign-Up Attempt Successful: Indicates the second sign-up attempt was successful and prints the retained values.
+Second Sign-Up Attempt Failed: Indicates the second sign-up attempt also failed, suggesting further investigation is needed.
+Notes
+Form Field IDs: Ensure the IDs used in the script match those in your web application.
+Password Fields: The script intentionally does not print password fields for security reasons.
+Adjust Wait Times: Modify the wait times as needed depending on your application's response times.
+Troubleshooting
+Element Not Found: Verify the element IDs and update them in the script.
+WebDriver Errors: Ensure the Chrome WebDriver is installed and matches your Chrome browser version.
+Connection Errors: Ensure the web application is running and accessible at the specified URL.
