# Phase 3: Test Concept Enhanced (test-concept-enhanced)

Analyze test requirements with Gemini using progressive L0-L3 test layers.

## Objective

- Use Gemini to analyze coverage gaps
- Detect project type and apply appropriate test templates
- Generate multi-layered test requirements (L0-L3)
- Scan for AI code issues

## Core Philosophy

- **Coverage-Driven**: Focus on identified test gaps from context analysis
- **Pattern-Based**: Learn from existing tests and project conventions
- **Gemini-Powered**: Use Gemini for test requirement analysis and strategy design
- **Single-Round Analysis**: Comprehensive test analysis in one execution
- **No Code Generation**: Strategy and planning only, actual test generation happens in task execution

## Core Responsibilities

- Coordinate test analysis workflow using cli-execution-agent
- Validate test-context-package.json prerequisites
- Execute Gemini analysis via agent for test strategy generation
- Validate agent outputs (gemini-test-analysis.md, TEST_ANALYSIS_RESULTS.md)

## Execution

### Step 1.3: Test Generation Analysis

#### Phase 1: Context Preparation

**Command prepares session context and validates prerequisites.**

1. **Session Validation**
   - Load `.workflow/active/{test_session_id}/workflow-session.json`
   - Verify test session type is "test-gen"
   - Extract source session reference

2. **Context Package Validation**
   - Read `test-context-package.json`
   - Validate required sections: metadata, source_context, test_coverage, test_framework
   - Extract coverage gaps and framework details

3. **Strategy Determination**
   - **Simple** (1-3 files): Single Gemini analysis
   - **Medium** (4-6 files): Comprehensive analysis
   - **Complex** (>6 files): Modular analysis approach

#### Phase 2: Test Analysis Execution

**Purpose**: Analyze test coverage gaps and generate comprehensive test strategy.

```javascript
Task(
  subagent_type="cli-execution-agent",
  run_in_background=false,
  description="Analyze test coverage gaps and generate test strategy",
  prompt=`
## TASK OBJECTIVE
Analyze test requirements and generate comprehensive test generation strategy using Gemini CLI

## EXECUTION CONTEXT
Session: {test_session_id}
Source Session: {source_session_id}
Working Dir: .workflow/active/{test_session_id}/.process
Template: ~/.ccw/workflows/cli-templates/prompts/test/test-concept-analysis.txt

## EXECUTION STEPS
1. Execute Gemini analysis:
   ccw cli -p "..." --tool gemini --mode write --rule test-test-concept-analysis --cd .workflow/active/{test_session_id}/.process

2. Generate TEST_ANALYSIS_RESULTS.md:
   Synthesize gemini-test-analysis.md into standardized format for task generation
   Include: coverage assessment, test framework, test requirements, generation strategy, implementation targets

## EXPECTED OUTPUTS
1. gemini-test-analysis.md - Raw Gemini analysis
2. TEST_ANALYSIS_RESULTS.md - Standardized test requirements document

## QUALITY VALIDATION
- Both output files exist and are complete
- All required sections present in TEST_ANALYSIS_RESULTS.md
- Test requirements are actionable and quantified
- Test scenarios cover happy path, errors, edge cases
- Dependencies and mocks clearly identified
`
)
```

**Output Files**:
- `.workflow/active/{test_session_id}/.process/gemini-test-analysis.md`
- `.workflow/active/{test_session_id}/.process/TEST_ANALYSIS_RESULTS.md`

#### Phase 3: Output Validation

- Verify `gemini-test-analysis.md` exists and is complete
- Validate `TEST_ANALYSIS_RESULTS.md` generated by agent
- Check required sections present
- Confirm test requirements are actionable

**Input**:
- `testSessionId` from Phase 1
- `contextPath` from Phase 2

**Expected Behavior**:
- Use Gemini to analyze coverage gaps
- Detect project type and apply appropriate test templates
- Generate **multi-layered test requirements** (L0-L3)
- Scan for AI code issues
- Generate `TEST_ANALYSIS_RESULTS.md`

**Output**: `.workflow/[testSessionId]/.process/TEST_ANALYSIS_RESULTS.md`

**Validation** - TEST_ANALYSIS_RESULTS.md must include:
- Project Type Detection (with confidence)
- Coverage Assessment (current vs target)
- Test Framework & Conventions
- Multi-Layered Test Plan (L0-L3)
- AI Issue Scan Results
- Test Requirements by File (with layer annotations)
- Quality Assurance Criteria
- Success Criteria

## Error Handling

### Validation Errors
| Error | Resolution |
|-------|------------|
| Missing context package | Run test-context-gather first |
| No coverage gaps | Skip test generation, proceed to execution |
| No test framework detected | Configure test framework |
| Invalid source session | Complete implementation first |

### Execution Errors
| Error | Recovery |
|-------|----------|
| Gemini timeout | Reduce scope, analyze by module |
| Output incomplete | Retry with focused analysis |
| No output file | Check directory permissions |

**Fallback Strategy**: Generate basic TEST_ANALYSIS_RESULTS.md from context package if Gemini fails

## Output

- **File**: `.workflow/[testSessionId]/.process/TEST_ANALYSIS_RESULTS.md`
