I addded some default tests.
I added some examples test cases.
Hi haferjir, I fix the issues mentioned by you.
I updated the description, you are given a date (as a parameter) and you need to return the date that will be 1 Gs from that given date.
Thanks I changed it to be more evident.
I changed slightly the description, (that the string can contain whitespaces and should calculate the scrabble score only of the letters in that string) and also added a couple of test to check for that.
