Ch 3 Testing for Failures

[dxypher]

You're saying “We’re testing not just for ideal results–the user selects a letter with results–but also for letters with no results.”, but this test is the really the same as the first test. There are results if you pass in 'J'.

I think you should change the letter being passed in to something like 'M' so there are no matching results. Maybe even change the expectation to something like:

expect(Contact.by_letter('K')).to be_empty
