Type @test, press enter. Public void, we'll give the test a name like converts single digit Roman. Now here test first development is going to guide us toward architecting the solution to the problem. We don't have any solution code yet. The test that we write will guide us toward the solution code. So we're looking for a method that returns an integer and our method will have a name like convert. And we'll take an input string, the input string is the Roman numeral that we're trying to convert. So we're looking for solution code that will look something like that.
