    The final rule to add to our convert method is words that start with a vowel. 0:00
    These words do not have any letters moved around. 0:06
    They just add the string ay to the end. 0:10
    We can duplicate one of our other tests. 0:14
    And we'll change the name to convertStartingVowelWordToPigLatin(). 0:20
    We'll need a new word that starts with a vowel. 0:29
    How about unit? 0:32
    Our expected results will be unitay, 0:35
    and we run our code. 0:40
    The force test fails as expected. 0:44
    By looking at the results, we can see that the convert 0:46
    method is moving the first letter U to the end of the word. 0:50
    Why don't you give it a try and see if you can make the last test pass. 0:54
    You can approach this in the same way as we did the consonant clusters. 0:59
    This time using the vowels A, E, I, O, and U. 1:03
    Test-driven development can seem overwhelming when you're first getting 1:10
    started with testing. 1:13
    And if you already have an application, it's not really feasible. 1:15
    You don't need to take an all or nothing approach. 1:19
    One test is better than no test. 1:23
    And each method that you test leaves your code better and 1:25
    more documented than it was before. 1:29
    You can add additional tests while you're fixing bugs or adding new features. 1:32
    In the next section, 1:37
    we'll look at how we can use PHP unit to test an existing project. 1:38
