Testing Relationships Between Classes

Quickstart

Clone, then:

$ bundle install
$ rspec
# You should see four pending tests

Instructions

Fill in the four tests in spec/secret_diary_spec.rb.

Don't:

• Change secret_diary.rb
• Add any new files
• Create any new classes

Do:

• Use double — Reference docs here
• Use expect(...).to receive(...) Reference docs here

Check your work

Remove lines 23 (@diary.read) and 28 (@diary.write(new_message)) from lib/secret_diary.rb.

Does SecretDiary still do what it's supposed to do?

Do your tests still pass or do they fail?

If your tests still pass, is there any way to write them which means they will fail if SecretDiary is broken in this way?
