Looking at the Shared Web Server settings for your account, you are using Basic authentication. Have you provided the Username and Password in SoapUI? (These are taken from the Username and Token found under Atom Management / <your test atom> / Shared Web Server / User Management).
https://test.connect.boomi.com/ws/soap is unique to all the users who are using boomi.
Then how do you differentiate yourself in making a call?
Your credentials should be configured prior to accessing the URL, that is what you should provide in shared web server settings in the user management tab.
Once you create a user specific to the cloud tenant of a specific account, then when you make calls to the URL you need to provide UN and PWD in accessing the WSDL.
With this, you will be able to get authorized and get the content of deployed processes on the cloud instance.
