It's saying exactly what the error is - you're using the user() function and passing it a value Appian does not recognise as a valid User. Note that the value for a User is case sensitive e.g. Arunkh is not the same as arunkh. You can avoid this type of error by passing in the value in your rule input as the correct datatype i.e. set ri!userName as type 'User' and not 'Text'. Appian won't let you pick an invalid User for your unit test.
user type is there as a data type for rule inputs in expression rule?
can you show how to set a rule input of user type?

Select "User" here, instead of "Text" as currently shown in your screenshot.
Can you quickly show ..because i can see user CDT ..iuser is a primitive data type right ?
It shows as CDT but you have to select Thats only
