Test Writing: Email to NetID

Created By: Geoffrey Challen

/ Version: 2021.8.0

Write a method called emailToNetID. It should take a String containing an @illinois.edu email like [email protected] and return the NetID, which in this case would be "hello", as a String. You can assume that the passed String will contain a single @ character. And you should assert that the passed String ends with @illinois.edu.

You will want to explore the various String methods to help you with this task, particularly split.

Test Design Challenge

You're challenge is to write tests for this problem described above.

• Provide a method named test that accepts no arguments and does not return a value.
• If the implementation of the class described above is incorrect, your test method should throw an exception.
• If it is correct, do not throw an exception.
• You may want to use Java's assert method
