As you’re a very friendly person, you would like to send a birthday note to all the friends you have. But you have a lot of friends and a bit lazy, it may take some times to write all the notes by hand.
The good news is that computers can do it automatically for you.
Imagine you have a flat file with all your friends :
last_name, first_name, date_of_birth, email
Doe, John, 1982/10/08, john.doe@foobar.com
Ann, Mary, 1975/09/11, mary.ann@foobar.comAnd you want to send them a happy birthday email on their birth date :
Subject: Happy birthday!
Happy birthday, dear <first_name>!How would this software look like ? Try to implement it so you can easily change :
- the way you retrieve the friends data
- the way you send the note
-
Friends born on February, 29th should have their Birthday greeted on February, 28th
-
Send a Birthday Reminder note when it is someone else birthday :
Subject: Birthday Reminder
Dear <first_name>,
Today is <someone_else_first_name> <someone_else_last_name>'s birthday.
Don't forget to send him a message !- Send a single Birthday Reminder note
Subject: Birthday Reminder
Dear <first_name>,
Today is <full_name_1>, <full_name_2> and <full_name_3>'s birthday.
Don't forget to send them a message !This kata is largely inspired by the work of Matteo Vaccari in http://matteo.vaccari.name/blog/archives/154
