# Phase 19 Summary: Tests for Phases 13-18

## At a Glance

**What this phase accomplished:** Wrote comprehensive test coverage for the campaign orchestration module (Phase 13), TUI data layer (Phases 16-17), and Film Noir theme/narrative system (Phase 18). Added 133 new tests across 9 test files.

|------|-------------|
| `tests/test_campaign_discovery.py` | 19 new tests for filesystem campaign discovery |
| `tests/test_campaign_missions.py` | 17 new tests for mission lifecycle (complete, unlock, start) |
| `tests/test_campaign_progress.py` | 12 new tests for progress aggregation across categories |
| `tests/test_campaign_orchestrator.py` | 6 new tests for campaign creation/resumption |
| `tests/test_theme_config.py` | 10 new tests for ThemeConfig, NarrativeConfig, registry |
| `tests/test_command_router.py` | 31 new tests for command parsing, aliases, arguments |
| `tests/test_tui_queries.py` | 17 new tests for query functions (header, status, missions, briefing) |
| `tests/test_theme_prompts.py` | 13 new tests for build_theme_prompt_vars, get_category_display_name |
| `tests/test_campaign_persister.py` | 8 new tests for persist_briefing_data, persist_pipeline_data |

### Key Functions Tested

| Function | Tests | Description |
|----------|------|-------------|
| `discover_campaigns()` | 19 | Filesystem scan returning CampaignInfo with orphan detection |
| `complete_mission()` | 7 | AVAILABLE/IN_PROGRESS → COMPLETED with unlock cascade |
| `unlock_mission()` | 5 | LOCKED → AVAILABLE escape hatch |
| `start_mission()` | 5 | AVAILABLE → IN_PROGRESS transition |
| `get_campaign_progress()` | 12 | Progress aggregation with category breakdown and security counts |
| `create_campaign()` | 4 | Full orchestration with mocked subsystems |
| `resume_campaign()` | 2 | Campaign discovery and selection |
| `CommandRouter.parse()` | 22 | Multi-word aliases, arguments, case-insensitive, property tests |
| `load_actionable_missions()` | 3 | IN_PROGRESS + AVAILABLE ordering |
| `build_theme_prompt_vars()` | 7 | Theme variable generation with fallbacks |

### Behavior Changes

- **Test coverage:** 904 tests → 1037 tests (133 new tests, 14.7% increase)
- **All campaign modules:** discovery, missions, progress, orchestrator, persister now have full test coverage
- **TUI data layer:** All query functions tested with mocked repositories
- **Theme system:** NarrativeConfig, vocab()/alias() helpers, build_theme_prompt_vars() fully tested
- **Command routing:** All 10 commands, multi-word aliases, argument extraction tested

## What Was Built

### 1. Campaign Discovery Tests (19 tests)

Tests for `discover_campaigns()` using real filesystem with tmp_path:

- Empty/missing campaigns directory handling
- Single and multiple campaign discovery
- Sorting by updated_at descending
- Orphaned campaign detection (missing marker, nonexistent repo path)
- Corrupt database handling (invalid SQLite, missing tables)
- Edge cases (empty marker, whitespace marker, null timestamps)

### 2. Mission Lifecycle Tests (17 tests)

Tests for `complete_mission()`, `unlock_mission()`, `start_mission()`:

- Status transitions (AVAILABLE → COMPLETED, LOCKED → AVAILABLE, AVAILABLE → IN_PROGRESS)
- Unlock cascade when all prerequisites met
- No unlock when prerequisites incomplete
- MissionStatusError for invalid transitions
- Error handling for nonexistent missions

### 3. Campaign Progress Tests (12 tests)

Tests for `get_campaign_progress()`:

- Empty campaign (all zeros, all 7 categories present)
- Mixed status computation
- 100% completion
- Percentage calculation
- Categories with no missions still appear
- Security-tagged mission tracking
- CategoryProgress field validation
- ALL_CATEGORIES constant verification

### 4. Campaign Orchestrator Tests (6 tests)

Heavy mocking tests for `create_campaign()` and `resume_campaign()`:

- Full orchestration returns ACTIVE campaign
- Progress callback sequence verification
- Non-git directory error
- Existing campaign deletion before recreation
- Empty campaigns returns None
- Most recent ACTIVE campaign selection

### 5. Theme Configuration Tests (10 tests)

Tests for `NarrativeConfig`, `ThemeConfig`, and registry:

- NarrativeConfig frozen dataclass verification
- Film Noir narrative field validation
- vocab() returns themed term with fallback
- alias() returns themed alias with fallback
- get_theme() returns populated ThemeConfig
- get_theme() raises ValueError for unknown theme
- list_themes() returns available themes

### 6. Command Router Tests (31 tests)

Tests for `CommandRouter`:

- Canonical command resolution
- Themed alias resolution (single and multi-word)
- Argument extraction
- Case insensitivity
- Whitespace handling
- Unknown command handling
- Property-based tests (parse always returns 2-tuple)

### 7. TUI Query Tests (17 tests)

Tests for all query functions with mocked repositories:

- load_header_data with all 7 fields
- load_status_data with category breakdown and chains
- load_available_missions filtering
- load_actionable_missions ordering (IN_PROGRESS first)
- load_mission_detail with file_refs and prerequisites
- load_briefing_data with fallback placeholder
- load_in_progress_missions
- load_chain_summaries

### 8. Theme Prompts Tests (13 tests)

Tests for `build_theme_prompt_vars()` and `get_category_display_name()`:

- Film Noir theme returns themed variables
- None parameter returns fallback values
- Four required keys invariant
- Empty narrative fields use fallback
- Title examples formatting
- Category display name lookup

### 9. Campaign Persister Additions (8 tests)

New tests added to existing file:

- persist_briefing_data with modules
- Empty modules handling
- Module ordering preservation
- Analysis structural data merging
- persist_pipeline_data empty result
- Root missions → AVAILABLE
- Missions with prereqs → LOCKED
- Out-of-range module_index warning

---

## Key Decisions

1. **Real filesystem for discovery tests:** Used tmp_path with real SQLite databases instead of mocking — tests actual filesystem scanning logic.

2. **Heavy mocking for orchestrator:** Patched all subsystems (analyze_repository, generate_briefing, run_mission_pipeline) — tests orchestration wiring, not subsystem logic.

3. **Property-based tests for CommandRouter:** Used Hypothesis to verify invariants (always returns 2-tuple, args always contain strings).

4. **All fields asserted:** Every test verifies all fields on returned objects per my-style/testing.md rules.

5. **Line length warnings deferred:** 27 E501 warnings in test files — style-only, tests pass, deferred as acceptable for test code readability.

## Major Logic Flows

### Test Organization

```
Phase 13 (Campaign) → 54 tests (discovery + missions + progress + orchestrator + persister)
Phase 16-17 (TUI) → 48 tests (commands + queries)
Phase 18 (Theme) → 23 tests (theme_config + theme_prompts)
Phase 14-15 (Factory/Validation) → 8 tests (persister additions for Film Noir fallback)
```

### Mock Strategy

```
Discovery: Real tmp_path filesystem (no mocking)
Missions/Progress: MagicMock for db.mission_repo
Orchestrator: patch() for all subsystems
Queries: MagicMock for db.* repos
Theme/Prompts: No mocking (pure logic)
```

## Connection to Previous Phases

- **Phase 13 (Campaign Orchestration):** Tests for discovery.py, missions.py, progress.py, orchestrator.py, persister.py
- **Phase 16 (TUI Layout):** Tests for commands.py, views.py, queries.py
- **Phase 17 (TUI Screens):** Tests for load_in_progress_missions, mission detail
- **Phase 18 (Film Noir Theme):** Tests for NarrativeConfig, vocab()/alias(), build_theme_prompt_vars()

This phase provides confidence that all business logic from Phases 13-18 works correctly. TUI widget rendering is not tested (requires Textual async harness) — validated via UA testing.
