Tests/SetSniffPropertyTest: use named data within data sets

This commit adds the parameter name for each item in the data set in an effort to make it more straight forward to update and add tests as it will be more obvious what each key in the data set signifies.

Includes minor array normalization.
Includes making the data type in the docblock more specific.
