bowling: add tests for rolling after bonus rolls #1189
Conversation
Currently, there are no tests confirming that a game with bonus rolls for a spare or strike in the 10th frame is complete. This PR adds a case for both spare and strike, attempting to roll an additional ball after the bonus rolls have been completed, expecting an error to be raised upon the roll attempt.

Maybe I am wrong here. But the 2nd ball in the 10th is a spare, which rewards the roller with 1 bonus roll, 2, yielding a score of 12.

You read it correctly. However, perhaps you missed the roll input field? In case there is any confusion, try pairing the rolls into frames.
| Frame No | Ball 1 | Ball 2 |
|---|---|---|
| 1 | 0 | 0 |
| 2 | 0 | 0 |
| 3 | 0 | 0 |
| 4 | 0 | 0 |
| 5 | 0 | 0 |
| 6 | 0 | 0 |
| 7 | 0 | 0 |
| 8 | 0 | 0 |
| 9 | 0 | 0 |
| 10 | 7 | 3 |
| Bonus | 2 (valid) | 2 (from "input": { "roll": 2 }) |

A strike in the 10th rewards the roller with two extra rolls. I count 15 in the 10th.

I have called these bonus rolls, the test description calls them fill balls.

Again, you counted correctly but neglected the roll input field.

Other tests already referred to them as bonus rolls, so I remained consistent the the other tests. Perhaps another PR would be in order to make the description and tests consistent, but that is another issue.

Test Description. |

I believe the cases are correct (if I am wrong, then two people made a same mistake and I made a mistake in https://github.com/petertseng/exercism-problem-specifications/blob/verify/exercises/bowling/verify.rb), the version is incremented appropriately, and this seems like an OK place for these tests.
Anyone observed a submitted implementation that behaves incorrectly under these new tests? So many tests that we had test for being able to score the game at the right time (when the game is complete) and possibly hopefully implementations reached the conclusion of not being able to roll exactly when the game is complete, but perhaps some implementation misses it.

I understand my err. |

For confirmation that these are not currently tested for, the current example solution in the Python track passes all existing tests, but fails these new tests.
