Writing Our Next Tests for Wordz

So, what should we write for our next tests? What would be a useful and small enough step so that we don’t fall into the trap of writing beyond what our tests can support? In this lesson, we’ll continue building out the Wordz application scoring system using TDD. We’ll discuss how we choose to move forward at each step. For the next test, a good choice is to play it safe and move only a small step further.

We’ll add a test for a single correct letter. This will drive out our first piece of genuine application logic.
