# Workflow Test-Fix Generation Command (/workflow:test-fix-gen)

## Overview

### What It Does

This command creates an independent test-fix workflow session for existing code. It orchestrates a 5-phase process to analyze implementation, generate test requirements, and create executable test generation and fix tasks.

**CRITICAL - Command Scope**:
- **This command ONLY generates task JSON files** (IMPL-001.json, IMPL-002.json)
- **Does NOT execute tests or apply fixes** - all execution happens in separate orchestrator
- **Must call `/workflow:test-cycle-execute`** after this command to actually run tests and fixes
- **Test failure handling happens in test-cycle-execute**, not here

### Dual-Mode Support

**Automatic mode detection** based on input pattern:

| Mode | Input Pattern | Context Source | Use Case |
|------|--------------|----------------|----------|
| **Session Mode** | `WFS-xxx` | Source session summaries | Test validation for completed workflow |
| **Prompt Mode** | Text or file path | Direct codebase analysis | Test generation from description |

**Detection Logic**:
```bash
if [[ "$input" == WFS-* ]]; then
  MODE="session"  # Use test-context-gather
else
  MODE="prompt"   # Use context-gather
fi
```

### Core Principles

- **Dual Input Support**: Accepts session ID (WFS-xxx) or feature description/file path
- **Session Isolation**: Creates independent `WFS-test-[slug]` session
- **Context-First**: Gathers implementation context via appropriate method
- **Format Reuse**: Creates standard `IMPL-*.json` tasks with `meta.type: "test-fix"`
- **Manual First**: Default to manual fixes, use `--use-codex` for automation
- **Automatic Detection**: Input pattern determines execution mode

### Coordinator Role

This command is a **pure planning coordinator**:
- Does NOT analyze code directly
- Does NOT generate tests or documentation
- Does NOT execute tests or apply fixes
- Does NOT handle test failures or iterations
- ONLY coordinates slash commands to generate task JSON files
- Parses outputs to pass data between phases
- Creates independent test workflow session
- **All execution delegated to `/workflow:test-cycle-execute`**

**Task Attachment Model**:
- SlashCommand invocation **expands workflow** by attaching sub-tasks to current TodoWrite
- When a sub-command is invoked (e.g., `/workflow:tools:test-context-gather`), its internal tasks are attached to the orchestrator's TodoWrite
- Orchestrator **executes these attached tasks** sequentially
- After completion, attached tasks are **collapsed** back to high-level phase summary
- This is **task expansion**, not external delegation

**Auto-Continue Mechanism**:
- TodoList tracks current phase status and dynamically manages task attachment/collapse
- When each phase finishes executing, automatically execute next pending phase
- All phases run autonomously without user interaction
- **⚠️ CONTINUOUS EXECUTION** - Do not stop until all phases complete

## Usage

### Command Syntax

```bash
# Basic syntax
/workflow:test-fix-gen [FLAGS] <INPUT>

# Flags (optional)
--use-codex        # Enable Codex automated fixes in IMPL-002
--cli-execute      # Enable CLI execution in IMPL-001

# Input
<INPUT>            # Session ID, description, or file path
```

### Usage Examples

#### Session Mode
```bash
# Test validation for completed implementation
/workflow:test-fix-gen WFS-user-auth-v2

# With automated fixes
/workflow:test-fix-gen --use-codex WFS-api-endpoints

# With CLI execution
/workflow:test-fix-gen --cli-execute --use-codex WFS-payment-flow
```

#### Prompt Mode - Text Description
```bash
# Generate tests from feature description
/workflow:test-fix-gen "Test the user authentication API endpoints in src/auth/api.ts"

# With automated fixes
/workflow:test-fix-gen --use-codex "Test user registration and login flows"
```

#### Prompt Mode - File Reference
```bash
# Generate tests from requirements file
/workflow:test-fix-gen ./docs/api-requirements.md

# With flags
/workflow:test-fix-gen --use-codex --cli-execute ./specs/feature.md
```

### Mode Comparison

| Aspect | Session Mode | Prompt Mode |
|--------|-------------|-------------|
| **Phase 1** | Create `WFS-test-[source]` with `source_session_id` | Create `WFS-test-[slug]` without `source_session_id` |
| **Phase 2** | `/workflow:tools:test-context-gather` | `/workflow:tools:context-gather` |
| **Phase 3-5** | Identical | Identical |
| **Context** | Source session summaries + artifacts | Direct codebase analysis |

## Execution Flow

### Core Execution Rules

1. **Start Immediately**: First action is TodoWrite, second is Phase 1 session creation
2. **No Preliminary Analysis**: Do not read files before Phase 1
3. **Parse Every Output**: Extract required data from each phase for next phase
4. **Sequential Execution**: Each phase depends on previous phase's output
5. **Complete All Phases**: Do not return until Phase 5 completes
6. **Track Progress**: Update TodoWrite dynamically with task attachment/collapse pattern
7. **Automatic Detection**: Mode auto-detected from input pattern
8. **Parse Flags**: Extract `--use-codex` and `--cli-execute` flags for Phase 4
9. **Task Attachment Model**: SlashCommand invocation **attaches** sub-tasks to current workflow. Orchestrator **executes** these attached tasks itself, then **collapses** them after completion
10. **⚠️ CRITICAL: DO NOT STOP**: Continuous multi-phase workflow. After executing all attached tasks, immediately collapse them and execute next phase

### 5-Phase Execution

#### Phase 1: Create Test Session

**Command**:
- **Session Mode**: `SlashCommand("/workflow:session:start --new \"Test validation for [sourceSessionId]\"")`
- **Prompt Mode**: `SlashCommand("/workflow:session:start --new \"Test generation for: [description]\"")`

**Input**: User argument (session ID, description, or file path)

**Expected Behavior**:
- Creates new session: `WFS-test-[slug]`
- Writes `workflow-session.json` metadata:
  - **Session Mode**: Includes `workflow_type: "test_session"`, `source_session_id: "[sourceId]"`
  - **Prompt Mode**: Includes `workflow_type: "test_session"` only
- Returns new session ID

**Parse Output**:
- Extract: `testSessionId` (pattern: `WFS-test-[slug]`)

**Validation**:
- **Session Mode**: Source session exists with completed IMPL tasks
- **Both Modes**: New test session directory created with metadata

**TodoWrite**: Mark phase 1 completed, phase 2 in_progress

---

#### Phase 2: Gather Test Context

**Command**:
- **Session Mode**: `SlashCommand("/workflow:tools:test-context-gather --session [testSessionId]")`
- **Prompt Mode**: `SlashCommand("/workflow:tools:context-gather --session [testSessionId] \"[task_description]\"")`

**Input**: `testSessionId` from Phase 1

**Expected Behavior**:
- **Session Mode**:
  - Load source session implementation context and summaries
  - Analyze test coverage using MCP tools
  - Identify files requiring tests
- **Prompt Mode**:
  - Analyze codebase based on description
  - Identify relevant files and dependencies
- Detect test framework and conventions
- Generate context package JSON

**Parse Output**:
- Extract: `contextPath` (pattern: `.workflow/[testSessionId]/.process/[test-]context-package.json`)

**Validation**:
- Context package created with coverage analysis
- Test framework detected
- Test conventions documented

**TodoWrite**: Mark phase 2 completed, phase 3 in_progress

---

#### Phase 3: Test Generation Analysis

**Command**: `SlashCommand("/workflow:tools:test-concept-enhanced --session [testSessionId] --context [contextPath]")`

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

**Expected Behavior**:
- Use Gemini to analyze coverage gaps and implementation
- Study existing test patterns and conventions
- Generate **multi-layered test requirements** (L0: Static Analysis, L1: Unit, L2: Integration, L3: E2E)
- Design test generation strategy with quality assurance criteria
- Generate `TEST_ANALYSIS_RESULTS.md` with structured test layers

**Enhanced Test Requirements**:
For each targeted file/function, Gemini MUST generate:
1. **L0: Static Analysis Requirements**:
   - Linting rules to enforce (ESLint, Prettier)
   - Type checking requirements (TypeScript)
   - Anti-pattern detection rules
2. **L1: Unit Test Requirements**:
   - Happy path scenarios (valid inputs → expected outputs)
   - Negative path scenarios (invalid inputs → error handling)
   - Edge cases (null, undefined, 0, empty strings/arrays)
3. **L2: Integration Test Requirements**:
   - Successful component interactions
   - Failure handling scenarios (service unavailable, timeout)
4. **L3: E2E Test Requirements** (if applicable):
   - Key user journeys from start to finish

**Parse Output**:
- Verify `.workflow/[testSessionId]/.process/TEST_ANALYSIS_RESULTS.md` created

**Validation**:
- TEST_ANALYSIS_RESULTS.md exists with complete sections:
  - Coverage Assessment
  - Test Framework & Conventions
  - **Multi-Layered Test Plan** (NEW):
    - L0: Static Analysis Plan
    - L1: Unit Test Plan
    - L2: Integration Test Plan
    - L3: E2E Test Plan (if applicable)
  - Test Requirements by File (with layer annotations)
  - Test Generation Strategy
  - Implementation Targets
  - Quality Assurance Criteria (NEW):
    - Minimum coverage thresholds
    - Required test types per function
    - Acceptance criteria for test quality
  - Success Criteria

**TodoWrite**: Mark phase 3 completed, phase 4 in_progress

---

#### Phase 4: Generate Test Tasks

**Command**: `SlashCommand("/workflow:tools:test-task-generate [--use-codex] [--cli-execute] --session [testSessionId]")`

**Input**:
- `testSessionId` from Phase 1
- `--use-codex` flag (if present) - Controls IMPL-002 fix mode
- `--cli-execute` flag (if present) - Controls IMPL-001 generation mode

**Expected Behavior**:
- Parse TEST_ANALYSIS_RESULTS.md from Phase 3 (multi-layered test plan)
- Generate **minimum 3 task JSON files** (expandable based on complexity):
  - **IMPL-001.json**: Test Understanding & Generation (`@code-developer`)
  - **IMPL-001.5-review.json**: Test Quality Gate (`@test-fix-agent`) ← **NEW**
  - **IMPL-002.json**: Test Execution & Fix Cycle (`@test-fix-agent`)
  - **IMPL-003+**: Additional tasks if needed for complex projects
- Generate `IMPL_PLAN.md` with multi-layered test strategy
- Generate `TODO_LIST.md` with task checklist

**Parse Output**:
- Verify `.workflow/[testSessionId]/.task/IMPL-001.json` exists
- Verify `.workflow/[testSessionId]/.task/IMPL-001.5-review.json` exists ← **NEW**
- Verify `.workflow/[testSessionId]/.task/IMPL-002.json` exists
- Verify additional `.task/IMPL-*.json` if applicable
- Verify `IMPL_PLAN.md` and `TODO_LIST.md` created

**TodoWrite**: Mark phase 4 completed, phase 5 in_progress

---

#### Phase 5: Return Summary

**Return to User**:
```
Independent test-fix workflow created successfully!

Input: [original input]
Mode: [Session|Prompt]
Test Session: [testSessionId]

Tasks Created:
- IMPL-001: Test Understanding & Generation (@code-developer)
- IMPL-001.5: Test Quality Gate - Static Analysis & Coverage (@test-fix-agent) ← NEW
- IMPL-002: Test Execution & Fix Cycle (@test-fix-agent)
[- IMPL-003+: Additional tasks if applicable]

Test Strategy: Multi-Layered (L0: Static, L1: Unit, L2: Integration, L3: E2E)
Test Framework: [detected framework]
Test Files to Generate: [count]

- Task list: .workflow/[testSessionId]/TODO_LIST.md

CRITICAL - Next Steps:
1. Review IMPL_PLAN.md (now includes multi-layered test strategy)
2. **MUST execute: /workflow:test-cycle-execute**
   - This command only generated task JSON files
   - Test execution and fix iterations happen in test-cycle-execute
   - Do NOT attempt to run tests or fixes in main workflow
3. IMPL-001.5 will validate test quality before fix cycle begins
```

**TodoWrite**: Mark phase 5 completed

**BOUNDARY NOTE**:
- Command completes here - only task JSON files generated
- All test execution, failure detection, CLI analysis, fix generation happens in `/workflow:test-cycle-execute`
- This command does NOT handle test failures or apply fixes

---

### TodoWrite Pattern

**Core Concept**: Dynamic task attachment and collapse for test-fix-gen workflow with dual-mode support (Session Mode and Prompt Mode).

#### Key Principles

1. **Task Attachment** (when SlashCommand invoked):
   - Sub-command's internal tasks are **attached** to orchestrator's TodoWrite
   - Example: `/workflow:tools:test-context-gather` (Session Mode) or `/workflow:tools:context-gather` (Prompt Mode) attaches 3 sub-tasks (Phase 2.1, 2.2, 2.3)
   - First attached task marked as `in_progress`, others as `pending`
   - Orchestrator **executes** these attached tasks sequentially

2. **Task Collapse** (after sub-tasks complete):
   - Remove detailed sub-tasks from TodoWrite
   - **Collapse** to high-level phase summary
   - Example: Phase 2.1-2.3 collapse to "Gather test coverage context: completed"
   - Maintains clean orchestrator-level view

3. **Continuous Execution**:
   - After collapse, automatically proceed to next pending phase
   - No user intervention required between phases
   - TodoWrite dynamically reflects current execution state

#### Lifecycle Pattern

```
Initial: [Phase 1: pending] [Phase 2: pending] [Phase 3: pending] [Phase 4: pending] [Phase 5: pending]
         ↓
Phase 2 Invoked (ATTACHED - mode-specific context gathering):
         [Phase 1: completed] [Phase 2.1: in_progress] [Phase 2.2: pending] [Phase 2.3: pending] [Phase 3: pending] [Phase 4: pending] [Phase 5: pending]
         ↓
Phase 2 Completed (COLLAPSED):
         [Phase 1: completed] [Phase 2: completed] [Phase 3: pending] [Phase 4: pending] [Phase 5: pending]
         ↓
Phase 3 Invoked (ATTACHED):
         [Phase 1: completed] [Phase 2: completed] [Phase 3.1: in_progress] [Phase 3.2: pending] [Phase 3.3: pending] [Phase 4: pending] [Phase 5: pending]
         ↓
Phase 3 Completed (COLLAPSED):
         [Phase 1: completed] [Phase 2: completed] [Phase 3: completed] [Phase 4: pending] [Phase 5: pending]
         ↓
[Continue pattern through Phase 4 and Phase 5...]
```

#### Test-Fix-Gen Specific Features

- **Dual-Mode Support**: Automatic mode detection based on input pattern
  - **Session Mode**: Input pattern `WFS-*` → uses `test-context-gather` for cross-session context
  - **Prompt Mode**: Text or file path → uses `context-gather` for direct codebase analysis
- **Phase 2**: Mode-specific context gathering (session summaries vs codebase analysis)
- **Phase 3**: Multi-layered test requirements analysis (L0: Static, L1: Unit, L2: Integration, L3: E2E)
- **Phase 4**: Multi-task generation with quality gate (IMPL-001, IMPL-001.5-review, IMPL-002)
- **Fix Mode Configuration**: `--use-codex` flag controls IMPL-002 fix mode (manual vs automated)

**Benefits**:
- Real-time visibility into attached tasks during execution
- Clean orchestrator-level summary after tasks complete
- Clear mental model: SlashCommand = attach tasks, not delegate work
- Dual-mode support: Both Session Mode and Prompt Mode use same attachment pattern
- Dynamic attachment/collapse maintains clarity

**Note**: Unlike other workflow orchestrators, this file consolidates TodoWrite examples in this section rather than distributing them across Phase descriptions for better dual-mode clarity.

## Task Specifications

Generates minimum 3 tasks (expandable for complex projects):

### IMPL-001: Test Understanding & Generation

**Agent**: `@code-developer`

**Purpose**: Understand source implementation and generate test files following multi-layered test strategy

**Task Configuration**:
- Task ID: `IMPL-001`
- `meta.type: "test-gen"`
- `meta.agent: "@code-developer"`
- `context.requirements`: Understand source implementation and generate tests across all layers (L0-L3)
- `flow_control.target_files`: Test files to create from TEST_ANALYSIS_RESULTS.md section 5

**Execution Flow**:
1. **Understand Phase**:
   - Load TEST_ANALYSIS_RESULTS.md and test context
   - Understand source code implementation patterns
   - Analyze multi-layered test requirements (L0: Static, L1: Unit, L2: Integration, L3: E2E)
   - Identify test scenarios, edge cases, and error paths
2. **Generation Phase**:
   - Generate L1 unit test files following existing patterns
   - Generate L2 integration test files (if applicable)
   - Generate L3 E2E test files (if applicable)
   - Ensure test coverage aligns with multi-layered requirements
   - Include both positive and negative test cases
3. **Verification Phase**:
   - Verify test completeness and correctness
   - Ensure each test has meaningful assertions
   - Check for test anti-patterns (tests without assertions, overly broad mocks)

### IMPL-001.5: Test Quality Gate ← **NEW**

**Agent**: `@test-fix-agent`

**Purpose**: Validate test quality before entering fix cycle - prevent "hollow tests" from becoming the source of truth

**Task Configuration**:
- Task ID: `IMPL-001.5-review`
- `meta.type: "test-quality-review"`
- `meta.agent: "@test-fix-agent"`
- `context.depends_on: ["IMPL-001"]`
- `context.requirements`: Validate generated tests meet quality standards
- `context.quality_config`: Load from `.claude/workflows/test-quality-config.json`

**Execution Flow**:
1. **L0: Static Analysis**:
   - Run linting on test files (ESLint, Prettier)
   - Check for test anti-patterns:
     - Tests without assertions (`expect()` missing)
     - Empty test bodies (`it('should...', () => {})`)
     - Disabled tests without justification (`it.skip`, `xit`)
   - Verify TypeScript type safety (if applicable)
2. **Coverage Analysis**:
   - Run coverage analysis on generated tests
   - Calculate coverage percentage for target source files
   - Identify uncovered branches and edge cases
3. **Test Quality Metrics**:
   - Verify minimum coverage threshold met (default: 80%)
   - Verify all critical functions have negative test cases
   - Verify integration tests cover key component interactions
4. **Quality Gate Decision**:
   - **PASS**: Coverage ≥ 80%, zero critical anti-patterns → Proceed to IMPL-002
   - **FAIL**: Coverage < 80% OR critical anti-patterns found → Loop back to IMPL-001 with feedback

**Acceptance Criteria**:
- Static analysis: Zero critical issues
- Test coverage: ≥ 80% for target files
- Test completeness: All targeted functions have unit tests
- Negative test coverage: Each public API has at least one error handling test
- Integration coverage: Key component interactions have integration tests (if applicable)

**Failure Handling**:
If quality gate fails:
1. Generate detailed feedback report (`.process/test-quality-report.md`)
2. Update IMPL-001 task with specific improvement requirements
3. Trigger IMPL-001 re-execution with enhanced context
4. Maximum 2 quality gate retries before escalating to user

### IMPL-002: Test Execution & Fix Cycle

**Agent**: `@test-fix-agent`

**Purpose**: Execute initial tests and trigger orchestrator-managed fix cycles

**Note**: This task executes tests and reports results. The test-cycle-execute orchestrator manages all fix iterations, CLI analysis, and fix task generation.

**Task Configuration**:
- Task ID: `IMPL-002`
- `meta.type: "test-fix"`
- `meta.agent: "@test-fix-agent"`
- `meta.use_codex: true|false` (based on `--use-codex` flag)
- `context.depends_on: ["IMPL-001"]`
- `context.requirements`: Execute and fix tests

**Test-Fix Cycle Specification**:
**Note**: This specification describes what test-cycle-execute orchestrator will do. The agent only executes single tasks.
- **Cycle Pattern** (orchestrator-managed): test → gemini_diagnose → manual_fix (or codex) → retest
- **Tools Configuration** (orchestrator-controlled):
  - Gemini for analysis with bug-fix template → surgical fix suggestions
  - Manual fix application (default) OR Codex if `--use-codex` flag (resume mechanism)
- **Exit Conditions** (orchestrator-enforced):
  - Success: All tests pass
  - Failure: Max iterations reached (5)

**Execution Flow**:
1. **Phase 1**: Initial test execution
2. **Phase 2**: Iterative Gemini diagnosis + manual/Codex fixes
3. **Phase 3**: Final validation and certification

### IMPL-003+: Additional Tasks (Optional)

**Scenarios for Multiple Tasks**:
- Large projects requiring per-module test generation
- Separate integration vs unit test tasks
- Specialized test types (performance, security, etc.)

**Agent**: `@code-developer` or specialized agents based on requirements

## Reference

### Error Handling

| Phase | Error Condition | Action |
|-------|----------------|--------|
| 1 | Source session not found (session mode) | Return error with source session ID |
| 1 | No completed IMPL tasks (session mode) | Return error, source incomplete |
| 2 | Context gathering failed | Return error, check source artifacts |
| 3 | Gemini analysis failed | Return error, check context package |
| 4 | Task generation failed | Retry once, then return error with details |

### Best Practices

1. **Before Running**:
   - Ensure implementation is complete (session mode: check summaries exist)
   - Commit all implementation changes
   - Review source code quality

2. **After Running**:
   - Review generated `IMPL_PLAN.md` before execution
   - Check `TEST_ANALYSIS_RESULTS.md` for completeness
   - Verify task dependencies in `TODO_LIST.md`

3. **During Execution**:
   - Monitor iteration logs in `.process/fix-iteration-*`
   - Track progress with `/workflow:status`
   - Review Gemini diagnostic outputs

4. **Mode Selection**:
   - Use **Session Mode** for completed workflow validation
   - Use **Prompt Mode** for ad-hoc test generation
   - Use `--use-codex` for autonomous fix application
   - Use `--cli-execute` for enhanced generation capabilities
