Manual testing Use a non-live site (e.g. localhost) for testing this. Checkout the 'main' branch (don't use this patch yet). Log in as admin Go to Site admin -> General -> Registration Fill out the form and register your site (you will get a 'hub cannot access your site...' warning, but that is ok). Because we are testing locally, we will need to manually confirm this sites registration. Find the registration_hub database table and update the 'confirmed' value to 1 Refresh your registration page and just ensure that the banner is reporting that your site is now registered. Apply this patch and purge your caches. Go to the registration page again. CONFIRM there is no banner stating 'Registration information has been changed'. CONFIRM there is a new select field called 'Organisation type'. Choose an option for 'Organisation type'. Submit the form (you will get a 'hub cannot access your site... warning, but that is ok). Go back to the registration form page. Refresh the page. CONFIRM that the option for 'Organisation type' is still set to what you chose.
