Bowling Game: Array of Frames: Step 6

After extracting a method called RollMany, the test code looks like this:

TEST_CLASS(BowlingGameTests)
{
    Game game;

    void RollMany(int rolls, int pins)
    {
        for (int i=0; i<rolls; ++i)
            game.Roll(pins);
    }
public:
    TEST_METHOD(AllGutterBallsMeansScoreIs0)
    {
        RollMany(20, 0);
        Assert::AreEqual(0, game.Score());
    }
    TEST_METHOD(AllOnesMeansScoreIs20)
    {
        RollMany(20, 1);
        Assert::AreEqual(20, game.Score());
    }
};

Nothing further to refactor. All combinations of pairs of numbers that don’t add up to 10 will work. Time for another test.

Maybe now would be a good time to validate that pins argument is not out of range. Let’s write such a test now.
