Bowling Game: State Machine: Unique_Ptr: Step 31

Refactoring to a switch statement that looks something like the switch statements in the other methods looks something like this:

    void AddSpare(int pins)
    {
        switch (bonusRolls)
        {
        case Bonus::NoBonusRolls: score += pins;   bonusRolls = Bonus::OneBonusRoll; ++frame; break;
        case Bonus::OneBonusRoll: score += pins*2; bonusRolls = Bonus::OneBonusRoll; ++frame; break;
        }
    }

Now, evidently I’m not smart enough to figure out if I’ll need those addition case statements, so I’ll write tests as if I do and see if they pass.

After writing this test,

    TEST_METHOD(TwoStrikesThenSpareAnd1BonusRollWorks)
    {
        RollMany(2, 10); // 2 strikes
        RollMany(2, 5); // spare
        game.Roll(1);
        RollMany(13, 0);
        Assert::AreEqual(57, game.Score());
    }

I see that it does indeed fail, with Assert failed. Expected:<57> Actual:<47>, meaning we’re missing a case statement.

Go ahead and write the code to pass this last test, too, and then click next.
