# Parameter :: `--dir`
Edge case tests for the working directory parameter. Tests validate path forwarding, missing-value rejection, and help documentation.
**Source:** [008_dir.md](../../../../docs/cli/param/008_dir.md)
## Test Case Index
| EC-1 | `--dir /some/path` → forwarded to assembled command | Behavioral Divergence |
| EC-2 | `--dir` without value → exit 1 | Missing Value |
| EC-3 | Default → cwd used (no `--dir` in assembled command) | Behavioral Divergence |
| EC-4 | `--dir` with non-existent path → accepted (not validated at this layer) | Permissive |
| EC-5 | `--help` lists `--dir` | Documentation |
| EC-6 | `--dir` + message → both forwarded correctly | Interaction |

- Missing Value: 1 test (EC-2)
- Permissive: 1 test (EC-4)
- Documentation: 1 test (EC-5)
- Interaction: 1 test (EC-6)
**Total:** 6 edge cases
## Test Cases
---
### EC-1: `--dir /some/path` forwarded
- **Given:** clean environment
- **When:** `clr --dry-run --dir /tmp "Fix bug"`
- **Then:** Assembled command contains `--dir /tmp`
- **Exit:** 0
- **Source:** [008_dir.md](../../../../docs/cli/param/008_dir.md)
- **Commands:** run, ask
---
### EC-2: `--dir` without value → exit 1
- **Given:** clean environment
- **When:** `clr --dir`
- **Then:** Exit 1; error about missing `--dir` value
- **Exit:** 1
- **Source:** [008_dir.md](../../../../docs/cli/param/008_dir.md)
- **Commands:** run, ask
---
### EC-3: Default → no `--dir` in assembled command
- **Given:** clean environment
- **When:** `clr --dry-run "Fix bug"`
- **Then:** Assembled command does NOT contain `--dir`
- **Exit:** 0
- **Source:** [008_dir.md](../../../../docs/cli/param/008_dir.md)
- **Commands:** run, ask
---
### EC-4: Non-existent path accepted without validation
- **Given:** clean environment
- **When:** `clr --dry-run --dir /no/such/path "Fix bug"`
- **Then:** Exit 0; assembled command contains `--dir /no/such/path` (no path validation at runner layer)
- **Exit:** 0
- **Source:** [008_dir.md](../../../../docs/cli/param/008_dir.md)
- **Commands:** run, ask
---
### EC-5: `--help` lists `--dir`
- **Given:** clean environment
- **When:** `clr --help`
- **Then:** Stdout contains `--dir`
- **Exit:** 0
- **Source:** [command/04_help.md](../../../../docs/cli/command/04_help.md)
- **Commands:** run, ask
---
### EC-6: `--dir` + message → both forwarded
- **Given:** clean environment
- **When:** `clr --dry-run --dir /workspace "Fix bug"`
- **Then:** Assembled command contains both `--dir /workspace` and the message
- **Exit:** 0
- **Source:** [008_dir.md](../../../../docs/cli/param/008_dir.md)
