In order to create a testing group, go to the 'Testing groups' app (Catalogue > Profiles > Testing groups)
You can also reach this app directly from the 'Manage profiles' app. After selecting a Profile table, click on 'Testing groups': it will only display the testing groups linked to this database. Therefore, you will not have to go through the 'Select profile DB' step.
A. Adding a testing group
All the existing testing groups from your databases are displayed.
To create a new one, click on the 'Add' button.
