Review Comment:
   Do these tests need to be added in the middle? Can it be in a new file or at 
the end of the old one?

Review Comment:
   Why not use regex to do the pattern matching and data extraction directly?
   `Basic` is short, and in the worst case we only need to assert the uppercase 
and lowercase format of each letter.
   There doesn't seem to be a significant means from using split.
   
   `[Bb][Aa][Ss][Ii][Cc]\\s(.*)`
   `(?i:basic)\\s(.*)`
