EXAMPLE

class Reminder def initialize(name) # name is a string # ... end

def remind_me_to(task) # task is a string # No return value end

def remind() # Throws an exception if no task is set # Otherwise, returns a string reminding the user to do the task end end 3. Create Examples as Tests Make a list of examples of how the class will behave in different situations.

EXAMPLE

1

reminder = Reminder("Kay") reminder.remind_me_to("Walk the dog") reminder.remind() # => "Walk the dog, Kay!"

2

reminder = Reminder("Kay") reminder.remind() # fails with "No task set."

3

reminder = Reminder("Kay") reminder.remind_me_to("") reminder.remind() # => ", Kay!" Encode each example as a test. You can add to the above list as you go.

4. Implement the Behaviour After each test you write, follow the test-driving process of red, green, refactor to implement the behaviour.
