| 2 | |
| 3 | ; This test uses a non-existent backend option to test that backend options are |
| 4 | ; being parsed. While it's more important that the existing options are parsed |
| 5 | ; than that this error is produced, this provides a reliable way to test this |
| 6 | ; scenario independent of any particular backend options that may exist now or |
| 7 | ; in the future. |
