Bonus: Email Parser Lab

Learning Goals

• Build a class that uses an initialize method
• Practice using an attribute accessor macro to make an attribute available to a class's methods
• Learn about Ruby's String.split method
• Learn about RegEx

Description

You will write a program that, given a string of email addresses, parses that string into an array.

Your class, EmailAddressParser, should take the string of addresses on initialization. Instances should respond to a parse instance method that parses the string into individual email addresses and returns them in an array.

I should be able to do this:

email_addresses = "[email protected], [email protected]"
parser = EmailAddressParser.new(email_addresses)

parser.parse
# => ["[email protected]", "[email protected]"]

Note: Your EmailAddressParser class should handle a list of email addresses that are separated by either spaces or commas. Additionally, the parse method should only return unique addresses.

Instructions

This lab is test-driven, so run the test suite to get started and use the test output to get the program working.

Hints:

In order to get this lab passing, you will need to do some research into the following topics:

• Ruby's String.split method
• RegEx - you'll use this to specify which characters to split the string on
