Bowling Game: State Machine: Step 7

We can use the handy Assert::ExpectException, like so:

TEST_METHOD(PinsArgumentIsInRange)
{
    Assert::ExpectException<std::out_of_range>([this]{ game.Roll(-1); }, L"'pins' cannot be negative");
    Assert::ExpectException<std::out_of_range>([this]{ game.Roll(11); }, L"'pins' must be <= 10");
}

Two Asserts in one test: some TDDers feel inordinately strongly that this shouldn’t be done. I’m not one of those, though I usually follow that advice.

When we build and test, the first Assert fires with Assert failed. 'pins' cannot be negative.

Now let’s add just enough code to pass all the tests so far.
