| 1 | """End-to-end CLI tests for ``muse code test``. |
| 2 | |
| 3 | Coverage: |
| 4 | - ``muse code test --history`` prints history header (no test runs). |
| 5 | - ``muse code test --flaky`` prints "No flaky tests found" when history empty. |
| 6 | - ``muse code test --dry-run`` prints targets without running pytest. |
| 7 | - ``muse code test --dry-run --json`` emits valid JSON. |
| 8 | - ``muse code test --all`` runs full pytest discovery on an explicit file. |
| 9 | - ``muse code test <file>`` runs a specific file. |
| 10 | - ``muse code test --ci`` executes CI gate suite. |
| 11 | - ``muse code test --ci --json`` emits valid JSON CI result. |
| 12 | - ``muse code test --json`` emits valid JSON run result. |
| 13 | - History is persisted to .muse/test_history.msgpack after a run. |
| 14 | - ``--no-save`` does not write history. |
